DPPV (+125 psi to -23 inHg) pump, 3/8" FBSP gauge adapter,
1m hose, 1/4― FBSPP process conn.
Create pressure or vacuum and calibrate
instrumentation using a pressure gauge or
calibrator attached to the pump (gauge or
calibrator not included)
• 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.
