RALSTON DP0V

Pneumatic Hand Pumps (direct acting)
DP0V (100 psi / 7 bar)
The most economical solution for very precise low pressure
calibration using a precision test gauge or pressure calibrator as the reference.
Features:
• Light weight, compact pump generates up to 100 psi (7
bar) with ease
• Large volume fine adjustment piston provides precise
control, even at very low pressures
• Modular design makes field maintenance quick and easy
• Precisely vent pressure with soft seated bleed valve
• Two outlet ports provide connections for both pressure
reference and for device under test thus eliminating a tee
• 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 temperature fluctuations
• Made in U.S.A.
