Claw Pump
Dry-Running Claw Vacuum Pumps
A claw vacuum pump is oil-free and dry-running: the rotors never touch each other or the casing, and no liquid seal is used. Process gas therefore passes through the machine without contacting oil or sealing water, which matters whenever contamination would ruin the process or the gas must be recovered clean.
Design
- Dry-Running Claw Vacuum Pump — oil-free claw-type vacuum pump for clean and slightly corrosive gas handling. No liquid seal, so the process gas is never contaminated.
Published performance range
Flow is published from 100 m³/h to 1500 m³/h, with an ultimate vacuum of 1 mbar or better (absolute) and motor power from 1.5 kW to 75 kW.
Where dry claw pumps fit
- Processes where oil contamination is unacceptable.
- Gas streams that must be recovered or discharged clean.
- Clean and slightly corrosive gas handling.
- Duty where a liquid seal would add cost or a waste stream.
Frequently asked questions
Is a claw vacuum pump oil-free?
Yes. The claw design is dry-running and oil-free, and it uses no liquid seal, so the process gas is never contaminated.
What vacuum level does it reach?
An ultimate vacuum of 1 mbar or better, in absolute terms, across a published flow range of 100–1500 m³/h.
What motor sizes are available?
Published motor power for the range is 1.5 kW to 75 kW.
