DPPV Datasheet, PDF (1/1 Pages) Ralston Instruments. – Pneumatic Pressure / Vacuum Hand Pumps

Pneumatic Pressure / Vacuum Hand Pumps (direct acting)
DPPV (100 psi / 7 bar) pressure, (-25” Hg / -635 mm Hg) vacuum
The ideal solution for either differential pressure or vacuum calibration
using a precision test gauge or pressure calibrator as the pressure refer-
ence.
Features:
Generate either 100 psi (7 bar) pressure or -25” Hg (-635 mm Hg) vacuum
with the same pump
Unique design allows the user to convert from pressure to vacuum by
simply twisting a knob, even with gloves on
Two outlet ports allow connection to reference pressure gauge or pressure
calibrator as well as device under test, thus eliminating a tee
Large volume fine adjustment piston provides precise control, even at very
low pressures
Precisely vent pressure with soft seated bleed valve
Low volume Quick-test hose, gauge adapter and process connection can
be attached to pump without thread sealant or a wrench
Rugged, all metal construction reduces pressure changes due to tempera-
ture fluctuations
Made in U.S.A.
