Air Over Hydraulic Pumps

Single or Double Acting

The PAWS PW-40 hydraulic pump is a single or double acting air driven unit that produces a range of 800-4,000 psi depending on the amount of air pressure delivered. Ideal for hydraulic clamping in CNC shop environments, the PAWS PWHP-40 provides excellent output flow and pressure to efficiently clamp and unclamp workholding fixtures.

Pumps come standard with air regulator, muffler, oil level sight gage, and pressure gage. Many options can be added to the pumps such as directional valves for M-code activated clamping and electric switches for monitoring system pressure.
