How to Use a Vacuum Pump for Robotic Material Handling
Automation is transforming industries ranging from electronics and logistics to packaging, food processing, printing, construction, and beyond. One of the most efficient, precise, and scalable methods for handling materials in these environments is robotic material handling, where automated systems pick, place, and transport materials with minimal human intervention.
While choosing the right industrial robot and software is critical, an often-overlooked factor is selecting the right vacuum pump for the job. Vacuum pumps play a crucial role in automated gripping systems, ensuring secure, efficient, and reliable material movement.
If you’re integrating robotic material handling into your operations, here’s what you need to know about choosing the right vacuum pump for the task.
How Vacuum Pumps Power Robotic Handling
Robotic pick-and-place applications rely on vacuum suction to grip, hold, and move objects. The process generally involves:
1️⃣ A vacuum pump creating suction, which is routed through tubes to an end-of-arm tool (EOAT), such as vacuum cups.
2️⃣ The EOAT grips the object, ensuring a secure hold as the robotic arm moves it to a designated location.
3️⃣ Once the object is placed, the vacuum is released, and the process repeats.
From placing products in boxes to moving heavy industrial components, vacuum-powered robotic handling can handle a wide range of materials and weights with high speed and precision.
Challenges in Robotic Material Handling
While vacuum automation simplifies operations, not all vacuum solutions are created equal. Selecting the wrong type of vacuum pump can result in:
⚠️ Inefficient suction, leading to dropped or misaligned items.
⚠️ Higher energy costs due to inefficient or excessive vacuum use.
⚠️ Increased downtime and maintenance if the pump isn’t suited to the materials being handled.
⚠️ Damage to delicate products if suction strength is too high or inconsistent.
Finding the right balance of power, efficiency, and precision is key to maximizing productivity.
Vacuum Pump Options for Robotic Handling
There are two primary vacuum pump types for robotic material handling:
1️⃣ Venturi Pumps – Use compressed air to create vacuum suction.
Pros: Lower upfront cost.
Cons: Higher energy consumption over time, requiring continuous compressed air.
2️⃣ Mechanical Vacuum Pumps – Generate vacuum using electric motors, offering greater efficiency.
Pros: More energy-efficient and cost-effective in the long run.
Cons: Higher initial investment.
Comparing Vacuum Pump Technologies
Each robotic handling system has unique needs, and different vacuum pumps offer distinct advantages.
1. Hook & Claw Vacuum Pumps
✅ Best for: Heavy objects and dense surfaces with small suction cups.
✅ Advantages:
✔ Medium vacuum, small-to-medium flow rate
✔ Operates efficiently across a range of pressures
✔ Low operating costs & maintenance-free design
💡 Why Choose Hook & Claw?
Becker’s Hook & Claw pumps feature integrated filters that double the standard filter surface area, ensuring longer service intervals. VARIAIR unit versions (VFDs) also provide vacuum on demand, reducing noise levels and improving efficiency.
⚠️ Considerations:
❌ Higher noise levels than other pump types.
❌ Higher initial investment but long-term efficiency gains.
2. Dry Rotary Vane Vacuum Pumps
✅ Best for: Dense objects & heavy lifting with smaller suction cups.
✅ Advantages:
✔ Medium vacuum, small-to-medium flow rate
✔ Lower initial cost compared to Hook & Claw pumps
✔ Easy to maintain and repair onsite
💡 Why Choose Dry Rotary Vane?
Becker oil-free rotary vane pumps have the longest vane life in the industry, reducing maintenance downtime. VARIAIR unit versions enable vacuum on demand, ensuring efficiency.
⚠️ Considerations:
❌ Requires regular maintenance (vane replacements and lubrication).
3. Regenerative Blowers
✅ Best for: Light objects, cardboard handling, and large suction cup tools.
✅ Advantages:
✔ High flow, low-to-medium vacuum
✔ Compact footprint & low exhaust temperatures
✔ Maintenance-free (bearing lifetime > 20,000 hours)
💡 Why Choose Regenerative Blowers?
Becker’s regenerative blowers are compact, efficient, and reliable for lightweight applications. VARIAIR units increase flow rates by up to 70%, providing superior handling for high-speed operations.
⚠️ Considerations:
❌ Limited vacuum range, making them unsuitable for dense or heavy objects.
4. Oil-Lubricated Rotary Vane Vacuum Pumps
✅ Best for: Moist or oily objects and high-altitude operations.
✅ Advantages:
✔ Higher vacuum levels than dry rotary vane pumps
✔ More robust where moisture or oily residues are a concern
✔ Ideal for high-altitude environments
💡 Why Choose Oil-Lubricated Rotary Vane?
Becker’s oil-lubricated pumps are built for moist or high-altitude applications and can be serviced easily. VARIAIR units optimize efficiency and noise levels.
⚠️ Considerations:
❌ Higher maintenance costs (oil changes & exhaust filter replacements).
❌ Oil mist exhaust may not be ideal for all environments.
Choosing the Right Vacuum Pump for Your Robotic System
To select the best vacuum pump, consider:
✔ Product Type – Is it light, heavy, delicate, porous, or oily?
✔ Required Accuracy – Does your operation need precise placement?
✔ Gripping Surface – Is the material textured or smooth?
✔ Speed & Force – How quickly and forcefully does the robot move?
