Operation
MAXIMUM WORKING PRESSURES
To reduce the risk of serious injury, including
fluid and splashing in the eyes or on the skin,
which may be caused if a component
ruptures:
Never exceed 1500 psi (10 MPa, 102 bar) Maxi-
mum Hydraulic Pressure to the reciprocator.
Never exceed 7500 psi (51 MPa, 517 bar) Maxi-
mum Outlet Pressure from the displacement pump.
Be sure all accessories added to the reciprocator
power supply side have at least a 1500 psi
(10 MPa, 102 bar) Maximum Working Pressure.
Accessories added to the pump fluid outlet side
should have at least a 7500 psi (51 MPa, 517 bar)
Maximum Working Pressure.
The working pressure of the displacement pump
has a 5:1 ratio to the pressure at which the recipro-
cator is operated. Therefore, if the fluid supplied to
the reciprocator is 1000 psi (7 MPa, 69 bar), the
pump fluid outlet pressure will be 5 times the hy-
draulic pressure, or 5000 psi (34 MPa, 345 bar).
WARNING
If the Pump Leaks at the Fluid Fittings
Tighten the fittings (1, 5, 58), which are self-sealing
and have replaceable o-rings. If leaking persists,
change the o-rings.

Shutdown
Relieve the pressure whenever you shut down.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
