Operation
Maximum Working Pressures
To reduce the risk of serious injury, including
fluid injection and splashing in the eyes or on the
skin, which may be caused if a component
ruptures:
D For models 239882, 224741, and 224742,
never exceed 1500 psi (10 MPa, 102 bar)
Maximum Hydraulic Pressure to the
reciprocator or Maximum Outlet Pressure from
the displacement pump.
D For model 237653, never exceed 1000 psi
(7 MPa, 69 bar) Maximum Hydraulic Pressure
to the reciprocator or Maximum Outlet Pressure
from the displacement pump.
D Be sure all accessories added to the
reciprocator power supply side or the pump fluid
outlet side have at least a 1500 psi (10 MPa,
102 bar) Maximum Working Pressure for
models 239882, 224741, and 224742; and at
least a 1000 psi (7 MPa, 69 bar) Maximum
Working Pressure for model 237653.
D The maximum working pressure of the
displacement pump is directly proportional to
the pressure at which the reciprocator is
operated. Therefore, if the fluid supplied to the
reciprocator is 1000 psi (7 MPa, 69 bar), the
pump fluid outlet pressure will also be 1000 psi
(7 MPa, 69 bar).
WARNING
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 9.

Models 239882, 224741, and 224742: Tighten
the fittings (1, 5, 58), which are self-sealing and
have replaceable o-rings. If leaking persists,
change the o-rings.
Model 237653: Tighten the fittings (B or K).
These fittings are self sealing and have
replaceable o-rings. If leaking persists, change
the o-rings.
