Identifying and Resolving Noise Issues in Vacuum Pumps
A vacuum pump running smoothly typically produces a steady humming sound. But what happens when that noise level rises or becomes irregular? Increased noise can signal potential issues that, if ignored, could lead to equipment failure. Here, we’ll explore common causes of loud vacuum pump noises and how to address them effectively.
Bobcat Industrial Air Services in Nashville, TN, is your trusted partner for diagnosing and repairing vacuum pump issues. Our team provides expert solutions to ensure your vacuum systems operate efficiently and reliably.
Normal Operating Sounds
Under standard conditions, vacuum pumps produce a consistent humming noise that shouldn’t interfere with normal conversation. Noise levels typically range between 59 dB and 83 dB, comparable to a household vacuum cleaner or hair dryer.
Certain pumps, like dry vane models, may generate clicking sounds during start-up, which subside as the pump reaches full speed. Similarly, oil-flooded pumps may emit clicks until properly lubricated, while regenerative blowers might roar briefly at start-up before settling into a quieter state.
Common Causes of Increased Noise
When a vacuum pump becomes excessively loud, the underlying cause often lies in mechanical or operational issues, such as:
Backward rotation
Worn or broken vanes
Vacuum or air leaks
Faulty O-rings or gaskets
Metal-to-metal contact in the chamber
Bearing failure or insufficient lubrication
Overheating or poor oil quality
Aging pumps are particularly susceptible to “washboarding,” where the internal surfaces develop corrugated patterns that increase noise and wear on components.
Troubleshooting Vacuum Pump Noises
Step 1: Isolate the Noise
Identify the part of the pump generating the noise. Refer to your maintenance guide for insights into normal operational sounds and how to inspect key components.
Step 2: Inspect and Maintain
Regular checks of the following can help pinpoint issues:
Bearings: Check for wear or overheating.
Vanes: Inspect for breakage, cupping, or sticking.
Filters: Ensure proper airflow by cleaning or replacing clogged filters.
Oil Quality: For lubricated pumps, confirm oil viscosity and replace degraded oil.
Step 3: Address Structural Issues
If washboarding or metal-to-metal contact is identified, professional repair or component replacement may be necessary.
Step 4: Seek Professional Support

Centrifugal Pump Flow Rate: Key Concepts
Centrifugal pumps are essential in industries ranging from water supply and wastewater treatment to oil & gas, chemical processing, and more. One of the most critical performance parameters for these pumps is flow rate, which determines efficiency, capacity, and energy consumption. At Bobcat Industrial Air Services, we help businesses optimize their pump systems by ensuring they meet the right flow rate requirements for maximum performance and longevity.
What is Flow Rate in Centrifugal Pumps?
✔ Definition: Flow rate is the volume of fluid transported per unit of time, typically measured in gallons per minute (GPM) or cubic meters per hour (m³/h). In centrifugal pumps, it represents the amount of liquid discharged over time.
✔ Why is Flow Rate Important?
🔹 Determines the pump’s ability to meet process requirements.
🔹 Affects energy efficiency—incorrect flow rates can increase energy costs.
🔹 Impacts system design—selecting the wrong flow rate may lead to pump failure or inefficiencies.
🔹 Plays a role in preventive maintenance—ensuring pumps function within optimal parameters reduces wear and tear.
Factors That Influence Centrifugal Pump Flow Rate
Understanding the variables that impact flow rate is crucial for selecting and maintaining an efficient pump system:
1. Pump Design & Impeller Characteristics
✔ Impeller size, number of blades, and blade angle determine how much fluid is moved per revolution.
✔ Larger impellers and higher blade angles typically generate higher flow rates.
2. Pump Speed & Impeller Diameter
✔ Pump speed (RPM) is directly related to flow rate—higher speeds usually result in higher discharge rates.
✔ Impeller diameter affects the amount of fluid pushed out per rotation—larger impellers increase flow rate.
3. System Resistance & Head Loss
✔ Resistance from pipes, valves, and fittings creates friction losses that reduce flow rate.
✔ Optimizing piping design and minimizing bends can improve pump efficiency.
4. Fluid Viscosity
✔ High-viscosity fluids require more energy to move, which reduces flow rate.
✔ Selecting the correct pump type and motor power ensures smooth flow for thick or abrasive liquids.
5. Cavitation & NPSH (Net Positive Suction Head)
✔ Cavitation occurs when fluid pressure drops below its vapor pressure, forming bubbles that damage impellers and reduce flow.
✔ Maintaining sufficient NPSH prevents cavitation, ensuring consistent pump operation.
Calculating Centrifugal Pump Flow Rate
To determine a pump’s flow rate, use the basic pump flow rate formula:
Q=π×D2×n×H4×gQ = \frac{\pi \times D^2 \times n \times H}{4 \times g}Q=4×gπ×D2×n×H
Where:
Q = Flow rate (m³/h or GPM)
D = Impeller diameter (meters)
n = Pump speed (RPM)
H = Head (meters)
g = Acceleration due to gravity (9.81 m/s²)
Example Calculation
For a centrifugal pump with:
Impeller diameter (D) = 0.5 meters
Speed (n) = 1500 RPM
Head (H) = 10 meters
Q=π×(0.5)2×1500×104×9.81Q = \frac{\pi \times (0.5)^2 \times 1500 \times 10}{4 \times 9.81}Q=4×9.81π×(0.5)2×1500×10Q=3.14×0.25×1500×1039.24Q = \frac{3.14 \times 0.25 \times 1500 \times 10}{39.24}Q=39.243.14×0.25×1500×10Q≈299.42m3/hQ ≈ 299.42 m³/hQ≈299.42m3/h
This means the pump will discharge approximately 299.42 cubic meters of fluid per hour under these conditions.
Using a Centrifugal Pump Flow Rate Calculator
Flow rate calculators eliminate manual calculations and allow quick adjustments to impeller size, speed, and head values to estimate real-world performance.
✔ How to Use a Flow Rate Calculator:
1️⃣ Enter pump parameters – Impeller diameter, speed, head, and system resistance.
2️⃣ Adjust for fluid properties – Some calculators allow you to input viscosity and density.
3️⃣ Obtain accurate results – The calculator instantly provides flow rate values in GPM or m³/h.
✔ Advantages of Online Calculators:

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.

How to Choose a Vacuum Pump
Selecting the right vacuum pump for your operation is critical to efficiency, cost savings, and minimizing downtime. Whether you're in secondary packaging, thermoforming, CNC routing, printing, composites, or another vacuum-reliant industry, choosing the right pump reduces maintenance costs and energy consumption while maximizing performance.
With so many vacuum pump technologies available, how do you make the best choice? Here’s a comprehensive guide to help you find the right vacuum solution for your needs.
Understanding Your Application’s Vacuum Needs
The first step in selecting a vacuum pump is understanding how and why you need vacuum in your process. The key factors include:
✅ Constant vs. Intermittent Vacuum – Does your process require a continuous vacuum, or does it need periodic suction with cycling on and off?
✅ Process Residues & Contaminants – Are there dust, particulates, or moisture that could enter the pump?
✅ Temperature Sensitivity – Does your operation require handling hot, cold, or fluctuating temperatures?
✅ Material Properties – Are there gases or substances that change state when vacuum is applied?
Each of these factors will determine which vacuum technology is best suited to your application.
Choosing the Right Vacuum Pump Technology

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.

Solving Common Vacuum Pump Problems
Vacuum pumps are critical components in many industrial applications, but they can encounter issues that disrupt operations and lead to costly downtime. At Bobcat Industrial Air Services in Nashville, TN, we understand the importance of keeping your vacuum systems running smoothly. Here, we’ll explore five common problems with vacuum pumps and provide practical solutions to help you maintain efficiency and reliability in your operations.
1. Voltage Mismatches
Improper wiring is a frequent issue that can damage or burn out a vacuum pump motor. Ensure the motor’s wiring matches the incoming voltage by checking the motor tag and wiring diagram. For three-phase motors, verify the rotation direction by bump-starting the unit. Remember, proper wiring and rotation are essential for the pump’s longevity.
2. Breaker Trips
If your pump consistently trips the breaker:
Verify the breaker’s amp rating matches the motor tag specifications.
Inspect the working chamber for metal-to-metal contact, broken vanes, or obstructions.
Regular maintenance and properly rated electrical systems can prevent this issue.
3. Loss of Vacuum or Pressure
Decreased performance often stems from inadequate maintenance:
Filters: Ensure inlet filters are clean and replace them if necessary. A flashlight test can quickly identify clogged filters.
Vanes: Inspect for wear, chips, or cupping. Damaged or sticking vanes reduce efficiency and may require replacement.
Oil Systems: For oil-lubricated pumps, check oil condition and flow. Contaminated or thickened oil can cause vane sticking and reduce lubrication.
4. Oil Misting from the Exhaust
Excessive oil mist can occur when:
The pump operates at less than optimal vacuum levels. Ensure it runs between 20-29”Hg.
Oil separators are saturated and need replacement.
The float chamber or scavenger line is clogged, starving the system of fresh oil. Regular inspections and maintenance resolve these issues.
5. Noisy Operation
Noise, such as chattering or screeching, often indicates:
New or improperly broken-in vanes: Allow the pump to run for 24-48 hours to break in.
Residual debris from previous vanes: Clean the cylinder walls thoroughly before installation.
Wear and tear on older pumps: Inspect for "washboarding" or ripples in the cylinder wall that require replacement to restore performance.
Proactive Maintenance Tips
To avoid downtime and expensive repairs:
Monitor Performance: Increased heat, noise, or vibration often signals issues. Address these early to prevent further damage.
Regular Inspections: Clean filters, measure vanes, and check oil levels routinely.
Secure Connections: Leaks in the system often result from loose plumbing or worn O-rings.
Repair or Replace?
Deciding whether to repair or replace a vacuum pump depends on the extent of the damage and cost-effectiveness:
Rebuild older pumps for backup use while installing a new one for critical operations.
Replace pumps with significant damage if rebuilding is cost-prohibitive.
