Overview
The Ralston DPPV is a pneumatic pressure / vacuum hand pump. Ralston describes it as a way to generate either a vacuum or a pressure for calibrating low-pressure or vacuum instrumentation using an external pressure calibrator as the reference.
DPPV-0000 configuration
Per Ralston, the DPPV-0000 pairs the pump with a 1/4" male NPT x male Quick-test process connection (brass, no check valve) and a 3 ft Quick-test 6,900 psi hose with brass ends.
