How It Works: Dry Claw Vacuum Pump

Denver, NC, August 2020: If you know the principles behind the rotary tooth compressor, then you’re well on your way to understanding the dry claw vacuum pump. While they perform opposite processes, the mechanisms are very similar. Let’s get started.

As the name suggests, these pumps do not require liquid to seal and lubricate the vacuum. This makes them extremely robust and able to withstand harsh operating conditions.

Like the rotary tooth compressor, dry claw pumps use two counter-rotating components to create compression and expansion. The rotors are nestled close to one another without touching, with minimal clearance between the claws.

As they rotate in the housing, the claws draw in air through an inlet. With every new intake, the pump simultaneously compresses another pocket of air. There are two compression cycles with every full rotation of the claws.

Dry claw pumps are ideal for applications that require low maintenance and increased process compatibility. They are suited for harsh environments, such as wastewater treatment plants, and are more efficient than some other types of pumps, including the rotary vane pump.

Because a dry claw pump system can be assembled into a multi-claw system, they can easily meet a facility’s unique requirements.
