Included in Hydraulic Fluid Control Kit 236864, which can be ordered separately.
Although the installation shown in Fig. 1 is only a guide
for selecting and installing system components and
accessories, some of the equipment is required, as
noted in the key. For assistance in designing a system
to suit your needs, contact your Graco distributor.
Mount the pump to suit the type of installation planned.
Maximum Working Pressure of Accessories
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, all
accessories added to the reciprocator power sup-
ply side must have at least a 1500 psi (10 MPa,
102 bar) maximum working pressure.
All accessories added to the pump fluid outlet side
must have at least a 7500 psi (51 MPa, 517 bar)
maximum working pressure.
WARNING
Pump Accessories
D
Follower plate (A) ensures a good prime.
Place the plate on the grease and rotate while
pressing firmly to level the material.
D
Pump outlet drain valve (D) helps relieve
fluid pressure in the pump when the pump is
shut off. Install the valve close to the pump
fluid outlet. Order Part No. 111229, valve.
WARNING
Pump Outlet Drain Valve
A pump outlet drain valve (D) is required in your
system. This valve helps relieve pressure in the
displacement pump and hose when shutting down
the system and in case of a clogged outlet hose.
Install the valve close to the pump outlet.
