Hydraulic Hand Pumps with Gauge Connection
HPGV (3000 psi / 210 bar), XHGV (5000 psi / 350 bar)
Fast and efficient hydraulic field testing of pressure trans-
mitters, gauges or switches is aided by an integral gauge
adapter which allows the user to quickly attach a preci-
sion test gauge to the pump.
Features:
• Portable, hand operated hydraulic pumps that easily
generate up to 5000 psi (350 bar)
• Fine adjustment piston provides an easy way to fine tune
exact pressure
• Bleed pressure slowly with soft seated vent valve
• Liquid reservoir holds enough fluid for multiple calibra-
tions
• Marine brass construction resists corrosion and abuse
• Quick-disconnect gauge adapter allows changing gauges
without using a wrench
• Low volume Quick-test hose, gauge adapter and process
connection can be attached to pump without thread
sealant or a wrench
• Made in U.S.A.
