Pneumatic Cylinder Hand Pumps – Overview The Pneumatic Cylinder Hand Pumps generate vacuum or a pressure for precisely calibrating low pressure or vacuum instrumentation using an external pressure calibrator. The Pneumatic Cylinder Hand Pumps include the DP0V Pressure Range (0 to 125 psi), DV0V Vacuum Range (0 to -23 inHg), and DPPV Vacuum and Pressure Range (-23inHg to 125 psi). The Pneumatic Cylinder Hand Pumps are an economical solution for the calibration of low-pressure differential transmitters. Simple direct-acting pump action with a fine adjustment piston makes an easy and precise pressure setting. Pneumatic Cylinder Hand Pumps – Features Modular design makes field maintenance quick and easy Two outlet ports provide connections for both pressure reference and the device under test 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 DVOV Lightweight, compact pump generates 23 inHg (584mm Hg)vacuum with ease Large volume fine adjustment piston provides precise control, even at very low vacuums DPPV Generate either 125 psi (8.6 bar) pressure or 23 InHg (584 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 DP0V Lightweight, compact pump generates 125 psi (8.6 bar) pressure with ease Precisely vent pressure with soft seated bleed valve
