What to Do if Your Vacuum Pump is Making a Loud Noise

Your vacuum pump may have been running smoothly for some time, all the while producing a continuous humming sound. But what does it mean when the noise level rises? Should you be concerned?

In this post, we examine the many possible reasons for loud noises or a rattling sound coming from a vacuum pump – and what to do to fix it.

NORMAL VACUUM PUMP SOUNDS

A normal vacuum pump will have a continuous humming sound during regular operation. The sound is measured at a standard of one meter (3ft) away from the pump. At this distance, you should be able to have a normal conversation.

At Becker, the noise level of typical pumps ranges from roughly 59db-83db @ 60Hz, depending on the product. This is comparable to a vacuum cleaner or hair dryer from one meter away. The volume may vary with the pressure level.

CLICKING SOUNDS

When using a soft starter or VFD/Phase converter with soft start programming, it is normal to hear a “clicking” sound as the pump starts. For a dry vane pump, the clicking sound should decrease or go away once the pump reaches full speed.

Some of the same clicking can be heard in oil-flooded pumps until oil properly lubricates the vanes as it cycles.

Becker SV Series single-stage regenerative blowers will start up accompanied by the roaring of air flow, which then settles down to a quiet sound in the contact-free environment.

REASONS FOR LOUD NOISE FROM A PUMP

Loud sounds coming from vacuum pump operations can be caused by a wide variety of issues, including:

Backward rotation
Washboarding of the housing
Poor bearing grease quality
Vane stuck in rotor slot
Broken vanes
Vacuum/Compressed air leak
Faulty O-ring around vacuum/pressure valve

Faulty gasket
Metal-to-metal contact within the working chamber
Faulty valve
Coupling disc failure
Cooling fan failure
Faulty bearing
Delaminated vanes (on lubricated pumps)

Worn vanes or damaged internal components can cause an increase in sound. After a new set of vanes is installed, allow for a break-in period of 24-48 hours when the sound level is high. Once the new vanes are seated properly, the noise will fall back to normal conditions.

Temperature issues are the leading cause of mechanical failures that can increase the sound levels.

Poor oil conditions for lubricated pumps cause the pump to work harder, which increases noise.

In general, the older the pump, the louder it becomes. After 9-10 years, the housing can become washboarded, or corrugated. This washboarding effect causes the vanes to chatter, significantly increasing sound levels.

IDENTIFY THE CAUSE

To pinpoint the cause, try to isolate the noise to a specific part of the pump. Working through the points in your pump’s maintenance guide can help determine where the sound originates, or if the sound is due to a gap in following the maintenance schedule.

Becker’s comprehensive guides outline how and when to perform maintenance tasks and show examples of damaged components. So, for example, check the vanes, filters, grease, and oil.

If the issue is deeper than just the standard maintenance points or the cause of increased noise cannot be isolated, the next step would be to call Becker’s Service Support experts.

DIAGNOSE AND FIX THE PROBLEM

Follow these steps to diagnose and potentially fix the vacuum pump noise.

For new installs, check the pump motor wiring and confirm the correct rotation. Make sure that all connections are sealed and tight.

For existing pumps, check maintenance points (bearings, oil, vane condition, etc.) and inspect housing/end shields, looking for signs of washboarding and/or signs of overheating. Inspect valve O-rings.

Washboarding is caused by age and excessive heat and typically requires repair. Metal-to-metal contact requiring replacement of any of the four major working chamber components requires professional Becker repair.

Becker allows our customers to diagnose and service their equipment more than most companies. This enables the user to be more independent when changing oil, vanes, and filters, or even inspecting the working chamber for signs of failing parts like housings, end shields, or bearings. The extent of customer repair is up to the expertise of the user. Becker’s repair team is always available when needed.

PREVENTATIVE MAINTENANCE: AVOID FUTURE NOISE ISSUES

Preventive maintenance is the best cure for almost all loud pump noise issues. Regularly inspecting/changing filters/vanes and other maintenance touchpoints will catch these problems before they become bigger, especially when it comes to noise. Rotation, and checking the bearings, filters, and vanes on schedule can all be done by the customer.

Each model has a recommended guideline for preventive maintenance. Each guide includes:

Maintenance intervals for each task
Tips to improve lifetime and performance
Part numbers for maintenance kits and disposables, such as filters

Download the specific maintenance guide for your pump or reach out to your Becker contact for maintenance interval information. And when in doubt, remember: Maintenance, maintenance, maintenance!

FULL-SERVICE PUMP REPAIRS

When it comes to deciding whether to replace or repair a pump, it is very difficult to determine by noise alone. An inspection of the pump is the best way to tell, and the answer will entirely depend on the cost of the repair/overhaul versus the price of a new replacement pump.

Becker not only offers a full-service center with factory-trained technicians ready to get you back up and running, but our mobile fleet is available to help with your maintenance needs and keep you running between rebuilds.

Centrifugal Pump Flow Rate: Key Concepts

Flow rate is a crucial parameter when it comes to understanding and operating centrifugal pumps effectively. Centrifugal pumps are widely used in various industries to transport fluids by converting rotational energy into hydrodynamic energy. They find applications in processes such as water supply, wastewater treatment, oil and gas, chemical processing, and more. To comprehend the principles behind centrifugal pump flow rate, it is important to explore its definition and significance within this context.

A. Definition of Flow Rate: Flow rate refers to the volume of fluid passing through a system per unit of time. In the context of centrifugal pumps, it represents the amount of fluid being discharged by the pump in a given time period. Flow rate is typically measured in units such as gallons per minute (GPM) or cubic meters per hour (m³/h).

B. Significance of Flow Rate in Centrifugal Pumps: Understanding flow rate is essential for several reasons. Firstly, it determines the pump’s capacity to deliver the required amount of fluid to the intended destination. Secondly, flow rate affects the pump’s efficiency, as variations from the design point can lead to inefficiencies and increased energy consumption. Additionally, flow rate plays a crucial role in system design, selection of the appropriate pump, and maintenance of the system’s operational parameters.

Factors Affecting Centrifugal Pump Flow Rate

A. Pump Design and Impeller Characteristics:
The design of the pump, particularly the impeller, significantly influences the flow rate. Impeller design parameters such as the number of blades, blade angle, and impeller diameter impact the pump’s performance and its ability to generate the desired flow rate.

B. Pump Speed and Impeller Diameter: The rotational speed of the pump, measured in revolutions per minute (RPM), and the impeller diameter are directly related to the flow rate. Higher pump speeds and larger impeller diameters generally result in higher flow rates, assuming other factors remain constant.

C. System Resistance and Head Loss: The resistance offered by the system, including pipes, valves, fittings, and other components, creates a head loss. Increased system resistance leads to a decrease in the flow rate. Understanding the system’s hydraulic characteristics and minimizing head losses are crucial for achieving the desired flow rate.

D. Viscosity of the Fluid: The viscosity of the fluid being pumped affects the flow rate. Higher viscosity fluids require more power to achieve the desired flow rate due to increased friction losses. Pump selection and system design must consider the fluid’s viscosity to ensure optimal performance.

E. Cavitation and NPSH: Cavitation occurs when the pressure at the impeller inlet drops below the vapor pressure of the fluid, causing the formation of vapor bubbles. This phenomenon can adversely affect the flow rate and pump performance. Net Positive Suction Head (NPSH) is a critical parameter that ensures the prevention of cavitation. Insufficient NPSH can result in decreased flow rates and damage to the pump.

Centrifugal Pump Flow Rate Formula

A. Understanding the Basic Formula: The flow rate (Q) of a centrifugal pump can be calculated using the pump calculation formula: Q = (π * D^2 * n * H) / (4 * g), where D represents the impeller diameter, n represents the pump speed (RPM), H represents the head, and g represents the acceleration due to gravity.

B. Components of the Pump Calculation Formula:

Q: Flow Rate, measured in the desired units (GPM, m³/h, etc.), represents the fluid volume delivered by the pump per unit of time.

D: Impeller Diameter, measured in the same units as the pump dimensions represents the size of the impeller, which affects the pump’s ability to generate flow.

n: Pump Speed (RPM), represents the rotational speed of the pump, which influences the flow rate.

H: Head, measured in units of length (feet, meters, etc.), represents the energy imparted to the fluid by the pump, determining its ability to overcome system resistance and achieve the desired flow rate.

g: Acceleration due to gravity, a constant value used to convert the units of the formula to match the desired flow rate units.

C. Example Calculation using the Formula: Let’s consider an example to illustrate the calculation of flow rate using the formula.

Suppose we have a centrifugal pump with an impeller diameter (D) of 0.5 meters, operating at a speed (n) of 1500 RPM, and generating a head (H) of 10 meters.

Assuming the acceleration due to gravity (g) is 9.81 m/s², the calculation would be as follows: Q = (π * 0.5^2 * 1500 * 10) / (4 * 9.81) Q = (3.14 * 0.25 * 1500 * 10) / (4 * 9.81) Q = 11775 / 39.24 Q ≈ 299.42 m³/h

Using a Centrifugal Pump Flow Rate Calculator

A. Overview of Flow Rate Calculators: Flow rate calculators provide a convenient way to determine the flow rate of a centrifugal pump without manual calculations. These tools utilize the flow rate formula and allow users to input the relevant parameters to obtain accurate results quickly.

B. Online Resources and Tools: Various online resources and engineering websites offer flow rate calculators specifically designed for centrifugal pumps. These calculators often provide additional functionalities, such as unit conversions and the ability to compare different pump configurations.

C. Step-by-Step Guide to Using a Calculator:

Input Parameters: Start by entering the required parameters into the calculator, such as impeller diameter, pump speed, head, and gravitational acceleration. Some calculators may also prompt you to specify the fluid properties or select predefined fluid types.

Obtaining the Flow Rate Result: After inputting the necessary parameters, click the calculate button or similar option provided by the calculator. The tool will process the inputs using the flow rate formula and provide the resulting flow rate value in the desired units.

D. Advantages and Limitations of Flow Rate Calculators: Flow rate calculators offer several advantages, including speed, convenience, and accuracy in obtaining flow rate values. They eliminate the need for manual calculations, reducing the potential for human error. However, it’s important to note that calculators rely on the accuracy of the input parameters, and users should ensure the data provided is reliable for precise results.

Practical Applications and Considerations

A. Selecting the Appropriate Pump for Desired Flow Rate: Understanding the flow rate requirements is essential when selecting a centrifugal pump. By considering factors such as system resistance, head, fluid properties, and desired flow rate, engineers can choose a pump that can meet the specified operational needs efficiently.

B. System Design and Optimization: Proper system design plays a significant role in achieving the desired flow rate. Factors such as pipe sizing, minimizing bends and fittings, and selecting appropriate valves contribute to reducing system resistance and optimizing flow rate performance.

C. Maintenance and Troubleshooting: Regular maintenance of centrifugal pumps is vital for ensuring optimal flow rate. Monitoring impeller condition, checking for blockages, maintaining proper lubrication, and addressing performance deviations are crucial for maintaining desired flow rates and extending the pump’s lifespan.

D. Real-world Examples and Case Studies: Real-world examples and case studies can provide practical insights into centrifugal pump flow rate applications. These may include scenarios where flow rate requirements were met successfully, challenges encountered and resolved, and the impact of flow rate on overall system performance.

Conclusion:

Understanding the centrifugal pump flow rate is crucial for efficient pump operation and system design. Engineers and operators can ensure optimal pump performance by grasping the key concepts, factors influencing flow rate, the flow rate formula, and utilizing flow rate calculators. Selecting the appropriate pump, considering system design and optimization, and implementing proper maintenance practices are essential for achieving and maintaining desired flow rates. By delving deeper into the subject and exploring real-world examples, individuals can further enhance their understanding of centrifugal pump flow rate and its significance in various applications.

Quality vs. Upfront Cost: Comparing Vacuum Pumps

It’s common for purchasing managers to choose a vacuum pump at or near the lowest price available. However, the quality of the pump significantly impacts the cost and performance of the pump over its lifespan.

In this article, we dive into the many factors affecting the lifetime cost of high-quality pumps versus cheaper pumps and show why price points can be deceiving and should not be the sole deciding factor in choosing a pump.

THE EFFECT OF QUALITY ON PERFORMANCE & LONGEVITY

The quality of a vacuum pump can impact its longevity, with lower-quality pumps demonstrating a shorter lifespan than higher-quality products. High-quality pumps and parts ensure reliability and durability as well as consistent performance.

Suppliers of high-quality pumps usually provide consultation with a specialist who will help determine the optimal solution for the application. For achieving the best results from your purchase, it’s crucial to make the right pump and accessory choices – an important step that is often overlooked.

In addition, suppliers of higher-quality products typically offer spare parts and after-sales services, which may not be available for low-budget solutions.

FOCUS ON TOTAL COST OF OWNERSHIP

One useful tool for making informed decisions that consider both quality and cost-effectiveness when selecting vacuum pumps is the “total cost of ownership”, or TCO.

To evaluate the quality factor against up-front costs, it’s helpful to calculate and compare the TCO of competing pumps for the first two and five years of operation. You may discover that replacing a pump every two or three years versus every eight or ten years, even if lower in cost, will ultimately cost more as the years go by.

WATCH FOR HIDDEN COSTS

By solely considering just a few factors, such as the upfront price of a vacuum pump, certain hidden costs that contribute to the TCO may be overlooked.

Calculating the TCO requires breaking down the factors that affect the lifetime costs of a pump, some of which may not be obvious or easily defined. These may include:

Lifespan of the pump
Maintenance intervals & cost of labor and consumables
Cost for part replacements
Energy efficiency
Easy availability of parts and services
Opportunity cost of machine downtime

IMPACT OF QUALITY ON MAINTENANCE REQUIREMENTS (AND MAINTENANCE COSTS)

Selecting the lowest-price vacuum pump option not only sacrifices quality but can also lead to a higher TCO through higher maintenance and energy costs.

For example, a lower-quality pump may be less efficient, requiring more energy for the same amount of vacuum produced. A less-well-built pump may lose efficiency due to leaking oil or worn parts, adding more repair and replacement costs.

A lower-quality, low-cost vacuum pump may require extra maintenance to keep the pump going for the same amount of time. To find out maintenance intervals, as well as the required maintenance tasks and consumables, it’s important to read the manufacturer’s instructions. Consider also that a lower-cost pump may tend to break down more easily, adding even more costs.

LONG-TERM BENEFITS

We’ve seen that the total financial investment in a specific vacuum pump can be estimated using TCO. And typically, machine downtime is the real cost driver.

A vacuum pump is often part of a larger machine so a broken pump can cause expensive and inconvenient downtime for the entire machine. A provider that is located near your plant that can supply fast service and delivery of the exact parts required can keep your operation running smoothly without interruptions.

The long-term benefits of choosing a higher-quality vacuum pump boil down to a simple formula:

Less Downtime = More Peace of Mind

By prioritizing quality and reliability when selecting a vacuum pump, and comparing the projected TCO of competing pumps, purchasing managers can strike a balance between upfront budget considerations and a vacuum pump’s long-term value and quality.

5 Common Problems With Vacuum Pumps

With so many types and brands of industrial vacuum pumps on the market today, a wide range of issues can arise that can negatively impact your business.

In this post, we examine the five most common problem areas and how to resolve them – whether repairing or replacing the pumps is necessary, or if less drastic solutions will work.

1. UNMATCHED VOLTAGE

A common issue encountered by users of all types of vacuum pumps is failing to ensure proper wiring of the motor to match the incoming voltage. This can damage or burn up the motor.

The motor wiring is determined by the incoming power supply. Once the incoming power is verified, the voltage ratings can be found on the motor tag (not to be confused with the pump tag).

Depending on the motor, the wiring can be set for multiple voltages. Three phase motors typically have two configurations: high voltage or low voltage. The correct configuration for these settings can be found inside the motor box cover or on the motor tag. If not present, contact Becker Support to obtain this information.

Rotation of the unit is crucial. This can be checked after the wiring has been installed and confirmed for the proper voltage by “bump starting” the unit and watching the fan for rotation.

Arrows to indicate proper rotation direction can be found on the outside protective cover or the motor flange. In a 3-phase setting, the direction of rotation can be changed by swapping two of the incoming leads. When bump starting any unit be sure the inlet and outlet of the pump are open to ambient air to allow the pump to rotate without restriction.

2. TRIPPING THE BREAKER

If a unit is continuously tripping a breaker so that the pump won’t turn on, further troubleshooting is required.

Start by checking that the breaker is rated for the proper values compared to the ones on the motor tag. For example, if a 20 amp breaker is installed but the motor is rated for 25 amps the breaker will overload and trip. Adjust the breaker for proper range and support.

If the pump has been in operation for some time and tripping is a new occurrence, first lockout/tagout the pump/motor to cut power to the motor.

Next, open the pump and inspect the working chamber for potential metal-to-metal contact, broken vanes, or other obstructions that are generating more resistance and causing a spike in amp draw.

Note: This step will vary depending on the pump type, if unsure how to access the working chamber for your specific model please contact Becker Support.

3. LOSS OF VACUUM/PRESSURE

A loss in vacuum or pressure can often be attributed to lack of pump maintenance. If the inlet filters are not periodically cleaned and/or replaced, the pump can starve of proper airflow, resulting in performance loss and potential failure.

To quickly check that your filters are clean and clear, hold a flashlight on the outside of the filter and look to see how much, if any, visible light shines through. If little to no light is visible after blowing the filter out, it’s time to change the filter. Additional technical options to determine a fliter’s health are available—contact Becker Support for more information.

A loss in pump performance can also be caused by sticking or worn vanes. To check this, start by removing and measuring the vanes to determine if they have worn past their minimum height tolerance. Inspect each vane for chips, breaks, abnormal wear, and cupping.

The maintenance sticker attached to the top of your vacuum pump will show the minimum specs for the vanes specific to your model.

Cupping can be found when laying all the vanes on top of one another and observing the end view. If visible light or “bowing” can be seen between the vanes, one or more may be beginning to cup. This can weaken the vanes so much that eventually, they break, resulting in a seized pump.

Vane cupping is only caused from overheating—please consult Becker’s Service Team for corrective actions immediately.

Another potential cause for loss in pump performance is sticking vanes that will not drop from the rotor. Contamination from the application or over-greasing can cause the vanes to stick. In an oil-lubricated pump, the vanes will stick if the oil becomes too thick. Lack of proper oil flow will cause lubricated vanes to delaminate and swell so that they stick in the rotor slots.

Cleaning out thick oil or running flushing oil through the pump can help to free up vanes and improve oil flow. In dry vane pumps, buildup of carbon vane dust in the rotor slots can cause vanes to stick. Compressed air and 220 grit sandpaper can be used to gently remove vane dust from the rotor slot.

4. OIL MISTING FROM THE EXHAUST

Misting oil from the exhaust port while the unit is running could be caused by several contributing factors.

First, Becker’s oil-lubricated pumps are best run at the deepest vacuum level they can reach. If your oil-lubricated pump is running at less than 20”Hg, there will be an increase in exhaust pressure as more ambient air is present in the pump. This will cause more oil to leave the pump. Ensure all connections are tight and not leaking on the inlet portion of the pump/application. Measure the vacuum level at the inlet of the pump and aim for a vacuum level of 20-29”Hg.

Second, an inspection of the oil separators should be done. Over time, oil will accumulate in the separators and they can become saturated. These filters collect oil particles from the exhaust air stream. If they become saturated, they cannot collect oil and it will be blown out of the exhaust port instead. The oil separator should be changed regularly, just like a normal air filter.

Third, check the float chamber. All oil-lubricated models will have a small “scavenger line” connecting the float chamber to either the inlet or B-side end shield. This chamber is located just below the oil separators in the exhaust of the pump.

If this line and/or the chamber becomes clogged or contaminated it will starve the working chamber of fresh oil to properly lubricate the vanes, and the float chamber to overfill with oil. The exhaust pressure traveling across this float chamber will cause oil to mist from the exhaust or just simply leak oil from the exhaust port/cover.

5. CHATTERING/SCREECHING SOUNDS

A question about noise often arises when customers initially install their pumps, especially dry vane pumps.

On initial startup, it is common to hear a “clicking” sound when the vanes drop out of their rotor slots due to centrifugal force and contact with the cylinder walls, especially at lower speeds. In most cases this is normal.

Additionally, when new vanes are installed or a freshly rebuilt unit is run for the first time, a very high-pitched screeching sound is sometimes generated. This noise is due to the vanes breaking in. Allow the pump to run for 24-48 hours. If the noise continues, please consult the Becker Service Team.

To help reduce or mitigate the noise issue when rebuilding a pump or even exchanging vanes for a new set, be sure to clean and clear out all vane debris from the previous set. Using a clean rag, brake cleaner, and compressed air, thoroughly clean the cylinder walls. If the vanes are trying to mesh to a contaminated/dirty cylinder the noise will take longer to go away and may never stop.

If the pump has been in operation for some time and you notice a new noise or an increase in noise or clicking while in operation, it’s time to check the filters, bearings, and vanes.

With older pumps, the cylinder wall will need to be inspected for “washboarding” – look for ripples or waves along the wall that form from extended use. Washboarding will cause the vanes to skip as they scrape across the cylinder walls, increasing heat and noise and a loss of vane life. Once washboarding begins the only fix is replacing the cylinder.

TIPS FOR PREVENTING VACUUM PUMP PROBLEMS

These five common problems with vacuum pumps can significantly impact the efficiency and reliability of your industrial processes. Any of these issues will undoubtedly disrupt the process with downtime that could be costly.

Here are some tips for how to get ahead of disruptions in your operations:

IDENTIFY POTENTIAL PROBLEMS QUICKLY

An increase in the running temperature of the pump can often indicate an issue that should be checked. The heat could be due to metal contact within the working chamber, broken vanes, wash boarding, bearing failures, oil viscosity, etc.

An increase in noise or vibration, or an increase in amps, should not be ignored. Contact the Service Center for further troubleshooting assistance.

The two most common causes of failure across any type of vacuum/pressure pump are ingestion of contaminants from the application and running the unit for too long on a clogged or restricted filter.

PERFORM PREVENTATIVE MAINTENANCE

Another main cause are gaps in the preventative maintenance schedule based on use and application. Follow the manufacturer’s recommendations, but recognize that these must be tailored to your specific needs to ensure you get the most out of your pump for years to come.

Periodically checking the filters, measuring the vanes, checking oil level and condition, and installing the proper external accessories to help protect the pump will all aid in extending its life.

Leaks in vacuum pumps or vacuum systems often can be attributed to a lack of tight and secure connections within the plumbing of the system.

Also, some specific Becker Pump models (KVT, DVT, KDT) have an O ring located around the collar of the vacuum relief valves that over time can dry rot, causing a leak directly at the valve. Your contact at Becker can assist you with the recommended guidelines as well as provide maintenance kit part numbers and pricing for your specific Becker model.

DECIDING BETWEEN REPAIR AND REPLACEMENT

Some customers will opt to have their old model rebuilt to use as a backup and put a new pump into operation. Due to extensive damage, some may be scrapped or sent back as is and a new one purchased because the cost of a new pump is less than rebuilding the old one.

Tips for Custom Vacuum Pump Design

For many applications, a custom vacuum pump design is the best way to get a fit-for-purpose solution that improves efficiency and doesn’t compromise on features. However, the customization is only worthwhile if it meets your specific needs.

Half of a successful design comes from working with an expert pump supplier, and the other half comes from your active participation in the design process. This style of partnership minimizes wasted time and money and maximizes the value of the final unit.

The process begins with your reason for seeking a unique solution.

Why get a custom vacuum pump design?

There are numerous reasons for customizing a vacuum pump. Whatever the specifics, behind every custom design, there should be an overarching business goal. Half of a successful design comes from working with an expert pump supplier, and the other half comes from your active participation in the design process.

Here are some common motivations for engaging a custom pump supplier.

One size doesn’t fit all

Using standard parts with specialized processes makes it nearly impossible to realize the highest efficiency and functionality. When it comes to a proprietary technique or advanced process, vacuum pump components that aren’t fit-for-purpose may limit performance.

Customization lets you realize the ideal design to support superior results.

Adapt to customer demands

As technology advances, customers are demanding better performance. It’s possible to lose business to a more agile competitor if your product doesn’t exceed expectations.

A tailored approach solves complex or situation-specific requirements. For example, this CNC manufacturer partnered with Becker Pumps, creating a custom vacuum pump design as a “drop-in” solution.

Seize a competitive advantage

Using the same components as the competition makes it difficult to differentiate your products in a crowded marketplace.

Developing a fit-for-purpose, custom vacuum pump design with advanced features and capabilities helps you fulfill opportunities where others cannot, making you the vendor of choice for select applications.

Examples of Custom Vacuum Pump Design

Healthcare – central medical/surgical vacuum systems, mobile vacuum systems.

Manufacturing – forming shaped plastics, additive manufacturing.

Material handling – holding, lifting, and moving products, pick and place.

Packaging – primary, secondary, tertiary.

Woodworking – wood drying and veneering, creating suction to aid with CNC work

Typical components involved in custom design:

Motor starters
External inlet filters
Check valves
Gauges
Sound abatement
Receiver tanks
Air/water (liquid) separators

Three Tips for a Successful Custom Design

Working with a vacuum pump supplier to create a custom unit is a team effort. It involves thorough consideration of the factors that go into a successful product while balancing reliability, functionality, cost, and efficiency.

Here are a few tips for developing a custom vacuum pump design.

1. Confirm performance specifics

Verifying the vacuum pump’s specifics up-front sets the stage for success. As the requester of a custom unit, you’ll want to convey your unique specifications to the supplier. This includes performance details, such as the unit’s capacity and the type of environment the pump will encounter.

Identifying the gas or vapor coming back to the pump is critical, as certain units can tolerate vapor in their chamber better than others. With particulates, like dust or wood chips, the supplier may need to consider an external filter to protect the pump from damage.

2. Know the physical limitations of your process

A custom-built unit should solve problems, not create them. Describing how you want the vacuum pump to contribute to your process will help the supplier design a unit that fits seamlessly into your existing operations.

Consider this; a lengthy pipe run leading to the vacuum pump may call for an external check valve, or space constraints may require modifications to the pump’s cover. Addressing operational realities during the design stage is far easier than making changes later.

3. Choose a supplier with a great reputation

Successful vacuum pump design has a lot to do with choosing the right pump supplier. The best suppliers have a wealth of industry experience and will listen closely and work together with you to develop a tailored design.

Ask for examples of the supplier’s previous work and talk to them about meeting your goals for the custom design. If they’re serious about custom work, they’ll be able to explain their process in detail.

Acid Pumps: Types, Benefits & Uses

Acid pumps are essential components in a variety of industrial processes and applications, where they play a crucial role in moving corrosive liquids and liquids with abrasive solids. In this comprehensive guide, we’ll cover everything you need to know about acid pumps, including how they work, their different types, and their benefits and limitations.

What are Acid Pumps?

Acid pumps are pumps designed to handle corrosive and abrasive liquids that would damage or destroy regular pumps. These pumps are made of materials that can withstand the harsh chemical environment, such as stainless steel, duplex steels, and often plastic based polymers. The materials used in the construction of acid pumps depend on the type of liquid being pumped and the concentration of the corrosive material.

How do Acid Pumps Work?

When referring to industrial acid pumps, their working mechanism depends on the specific type of pump used. Here are two common types and their operating principles:

1. Air-operated double diaphragm (AODD) pumps:

These pumps have two flexible diaphragms separated by a chamber filled with the acidic liquid.
Compressed air pushes one diaphragm forward, drawing liquid into the chamber on the other side.
When the first diaphragm reaches its limit, the air pressure switches, pushing the second diaphragm forward and expelling the liquid.
This cycle repeats, creating a pulsing flow of the acidic liquid.
Since the diaphragms don’t contact the liquid directly, they eliminate the risk of leaks and contamination.

2. Centrifugal pumps:

These pumps use a rotating impeller to create centrifugal force, flinging the liquid outwards.
The liquid exits the pump through a discharge nozzle due to the pressure generated.
Centrifugal pumps can handle high flow rates but may not be suitable for highly viscous acids or those containing solids.
Depending on the acid’s specific properties, special materials like stainless steel or lined casings are used to prevent corrosion.

Additional factors influencing acid pump operation:

Flow rate and pressure requirements: These determine the pump size and type needed.
Liquid viscosity and abrasiveness: Certain pumps are better suited for specific viscosities and abrasive solids.
Temperature of the acid: Some pumps have limitations on the temperature they can handle.
Safety features: Explosion-proof models may be necessary for hazardous environments.

It’s important to choose the right acid pump based on your specific needs and the properties of the liquid you’re handling. Consulting with a pump expert can ensure you get the most suitable and reliable pump for your application.

Types of Acid Pumps

The specific type of acid pump you need depends on several factors, including the type of acid, flow rate, pressure requirements, viscosity, and abrasiveness. Here are some common types of acid pumps:

1. Centrifugal Pumps:

Operation: Uses a rotating impeller to create centrifugal force, flinging the liquid outwards and generating pressure.
Suitable for: Low to medium viscosity acids, high flow rates.
Limitations: Not ideal for highly viscous acids, abrasive solids, or shear-sensitive liquids.
Material: Special materials like stainless steel or lined casings are used to prevent corrosion.

2. Air-operated Diaphragm (AODD) Pumps:

Suitable for: Highly viscous acids, abrasive solids, shear-sensitive liquids, self-priming applications.
Limitations: Pulsating flow, lower flow rates compared to centrifugal pumps.

3. Gear Pumps:

Operation: Two intermeshing gears create suction and pressure to move the liquid.
Suitable for: High viscosity acids, shear-sensitive liquids, precise metering.
Limitations: Lower flow rates, higher cost compared to other types.

4. Peristaltic Pumps:

Operation: Uses a roller to squeeze a flexible tube, creating suction and pushing liquid forward.
Suitable for: Shear-sensitive liquids, slurries, metering applications.
Limitations: Lower flow rates, limited pressure head.

5. Magnetic Drive Pumps:

Operation: Uses a magnetic coupling to rotate the impeller, eliminating the need for a shaft seal that could leak.
Suitable for: Hazardous or toxic acids, volatile liquids, environments with strict leak prevention requirements.
Limitations: Higher cost compared to other types.

6. Metering Pumps:

Operation: Designed for precise delivery of small volumes of liquids.
Suitable for: Dosing applications, chemical feed, laboratory use.
Limitations: Lower flow rates, higher cost compared to other types.

Additional factors to consider:

Temperature of the acid: Some pumps have limitations on the temperature they can handle.

How to Choose a Vacuum Pump

Choosing the right vacuum pump can ensure that your operations will be the most cost and energy-efficient, with the least maintenance and minimal downtime.

In this article, the experts at Becker offer their advice on how to make the optimal selection for your application – whether it be secondary packaging, thermoforming, composites, CNC routing, printing, or any other industry that relies on vacuum pumps.

The key factors to consider when selecting a vacuum pump will depend on the specifics of the application. For example, the type of vacuum technology needed will hinge on whether you require constant or intermittent vacuum.

Other application parameters affecting the choice will include temperature, moisture, particulates, or process residues. Also, consider if there are certain contaminants and/or materials present that could affect the vacuum or change when vacuum is applied.

Once these application parameters are nailed down, the main factors that will determine the specific make and model vacuum pump to choose are:

Required vacuum level
Volume flow (cfm)
Piping/setup

Lastly, take into account your willingness to provide maintenance/service at the recommended intervals. The amount of time and investment required for these activities depends on the make and model of the pump.

Generally speaking, filtration and the right ambient conditions keep the pump healthy.

CONSEQUENCES OF CHOOSING THE WRONG VACUUM PUMP

When choosing the best vacuum pump for a specific application it’s crucial to apply the right amount of vacuum. For instance, a food product could start boiling if the vacuum level is too high. This can lead to a damaged product and additionally, the vapor may damage the pump.

In other instances, e.g. vacuum fixing or pick and place operations, too low a vacuum level can result in a risk for machine operators and machines due to a lack of clamping force.

The wrong pump choice may influence the process outcome, energy efficiency, service intervals, and many other aspects critical to your operation. Because of these factors, anything could happen – from an explosion or fire, to not working properly or the product/process being affected negatively.

VACUUM LEVELS

Vacuum pressure levels are generally classified as rough, medium, or high vacuum. Different companies and experts talk about vacuum levels differently and use different measurement units, so it’s important to clarify. Vacuum pressure can be measured in units of Torr, millibar, microns, or inches of mercury, Pascals (Pa), psi, etc.

So, for instance, a rough vacuum theoretically goes up to 1 millibar or roughly 29.8 inches of mercury. At Becker, we don’t use these terms scientifically, so when we say rough vacuum, we’re typically referring to about 15-20” of mercury or less.

There is a caveat to this. Most vacuum pump manufacturers, ourselves included, say we offer “full vacuum” pumps or to 29.99” of mercury. However, it’s rare for most industrial applications to require that level of vacuum. Most customers who say “I need full vacuum” don’t actually need it, and most companies like Becker will use the term “full vacuum” to mean something above 29” and then further qualify on a per-application basis.

VACUUM VS. FLOW

A vacuum occurs in any place where the gas pressure is lower than the Earth’s atmospheric pressure, which is approximately 14.7 psi (pounds per square inch). To create a vacuum, there must be a flow of gas or liquid from one location to another. Molecules of gas are constantly moving, putting pressure on the surrounding surfaces. As molecules are pumped away from an area, the pressure drops, and a vacuum is created.

Sometimes customers need a high flow but only a low vacuum level. For instance, a fan moves air at a high rate of flow but doesn’t create a vacuum (or only a very nominal vacuum). Other times a customer may need a really high vacuum level. The higher the vacuum, the lower the flow.

In “real” terms this makes sense. A vacuum has to pull molecules from somewhere which causes a corresponding reaction. To get high levels of vacuum, eventually, the flow will have to decrease as you’re pulling from less available volume.

GENERAL RECOMMENDATIONS FOR BECKER PUMPS

Rough vacuum – less than 15” of mercury. With less than 15” customers will also typically need higher flows. We’d recommend a regenerative blower.

Medium vacuum – 15” to 26” of mercury. We recommend dry rotary vane lines.

High vacuum – 26” to 29.92” of mercury. We recommend lubricated vane or claw pumps.

Fine or ultra vacuum – 29.92” of mercury and up. Screw pumps, and other lubricated pumps.

FINAL ADVICE ON CHOOSING A VACUUM PUMP

Finally, specific features or technologies can enhance the functionality and versatility of the vacuum pump you select. These may include filtration, the correct oil (in lubricated pumps), and gas ballast valves.

Remember, in the case of vacuum pumps, bigger is not always better! An oversized pump is only sometimes beneficial. Focusing on the volume flow and pressure level is more important than the installed motor – a larger motor is often a waste of money.

Becker Pumps is a leading manufacturer of vacuum pumps for a wide range of industries and applications. We have the knowledge and expertise to help you make the right pump selection for your specific needs.

5 Common Problems With Vacuum Pumps

With so many types and brands of industrial vacuum pumps on the market today, a wide range of issues can arise that can negatively impact your business.

In this post, we examine the five most common problem areas and how to resolve them – whether repairing or replacing the pumps is necessary, or if less drastic solutions will work.

1. UNMATCHED VOLTAGE

A common issue encountered by users of all types of vacuum pumps is failing to ensure proper wiring of the motor to match the incoming voltage. This can damage or burn up the motor.

The motor wiring is determined by the incoming power supply. Once the incoming power is verified, the voltage ratings can be found on the motor tag (not to be confused with the pump tag).

Rotation of the unit is crucial. This can be checked after the wiring has been installed and confirmed for the proper voltage by “bump starting” the unit and watching the fan for rotation.

2. TRIPPING THE BREAKER

If a unit is continuously tripping a breaker so that the pump won’t turn on, further troubleshooting is required.

If the pump has been in operation for some time and tripping is a new occurrence, first lockout/tagout the pump/motor to cut power to the motor.

Next, open the pump and inspect the working chamber for potential metal-to-metal contact, broken vanes, or other obstructions that are generating more resistance and causing a spike in amp draw.

Note: This step will vary depending on the pump type, if unsure how to access the working chamber for your specific model please contact Becker Support.

3. LOSS OF VACUUM/PRESSURE

The maintenance sticker attached to the top of your vacuum pump will show the minimum specs for the vanes specific to your model.

Vane cupping is only caused from overheating—please consult Becker’s Service Team for corrective actions immediately.

4. OIL MISTING FROM THE EXHAUST

Misting oil from the exhaust port while the unit is running could be caused by several contributing factors.

5. CHATTERING/SCREECHING SOUNDS

A question about noise often arises when customers initially install their pumps, especially dry vane pumps.

If the pump has been in operation for some time and you notice a new noise or an increase in noise or clicking while in operation, it’s time to check the filters, bearings, and vanes.

TIPS FOR PREVENTING VACUUM PUMP PROBLEMS

Here are some tips for how to get ahead of disruptions in your operations:

IDENTIFY POTENTIAL PROBLEMS QUICKLY

An increase in noise or vibration, or an increase in amps, should not be ignored. Contact the Service Center for further troubleshooting assistance.

The two most common causes of failure across any type of vacuum/pressure pump are ingestion of contaminants from the application and running the unit for too long on a clogged or restricted filter.

PERFORM PREVENTATIVE MAINTENANCE

Periodically checking the filters, measuring the vanes, checking oil level and condition, and installing the proper external accessories to help protect the pump will all aid in extending its life.

Leaks in vacuum pumps or vacuum systems often can be attributed to a lack of tight and secure connections within the plumbing of the system.
