Pneumatic Pressure/Vacuum Hand Pumps (direct acting)
The ideal solution for either differenctial pressure or vacuum calibration using a precision test gauge or pressure calibrator as the pressure reference.
Features:
-
Generate either 100psi pressure or -25Hg 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 temperature fluctuations
-
