1HP7 - Hand Pump
50 bar (725 psi)
Description
This hand pump has been
designed to be used on
machines which require
emergency release of
brakes or for pilot supply
for emergency lowering of
access platforms. It can also
be utilized in the lubrication
circuits.
Operation
Depressing the plunger will
force oil out through a check
valve and into the system.
The plunger will then retract
drawing oil into the chamber
through a second check valve.
Features
Built in pressure and suction
checks. Self contained cartridge
element. Low leakage ball and
seat design. Minimal effort
required for plunger movement.
