Pneumatic Pressure/Vacuum Hand Pumps

Generate vacuum or a pressure for calibrating low pressure or vacuum instrumentation using an external pressure calibrator

  • 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
  • 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
  • Made in U.S.A.
