The DPPV pump is a lightweight, compact pump that generates vacuum to -23"Hg (584mm Hg) and pressure to 9 bar (125 psi) with ease. A large volume fine adjustment piston provides precise control, even at the top of its range. The modular design makes field maintenance quick and easy, and you are able to precisely vent pressure with the soft seated bleed valve. Two outlet ports provide connections for both your pressure reference and for the device under test eliminating the need for a tee. The pump features Ralston's popular Quick-test connectors allowing attachment of the hose and process connector (included) to pump without thread sealant or a wrench. Rugged, all metal construction reduces pressure changes due to temperature fluctuations.

The DPPV pump should be used with dry, inert gas or air & an in-line filter to ensure process contaminants are not introduced into the pump during use.
