Description
The Ralston DPPV-0000 Pneumatic Pressure and Vacuum Hand Pump with 1/4" Male NPT Process Connection generates vacuum or pressure for calibrating low pressure or vacuum instrumentation using an external pressure calibrator (not included). It enables users to generate either 125 psi (8.6 bar) pressure or 23 InHg (584 mm Hg) vacuum with the same pump. The unique design allows the user to convert from pressure to vacuum by simply twisting a knob, even with gloves on. Two outlet ports provide connection to a reference pressure gauge or pressure calibrator as well as device under test, thus eliminating a tee. The large volume fine adjustment piston provides precise control, even at very low pressures. Users can also precisely vent pressure with the soft seated bleed valve.
