Installation Instructions
Pump Accessories
Pump Outlet Drain Valve (D)
: helps relieve fluid pres-
sure in pump when pump is shut off. Install valve close
to pump fluid outlet.
Pump Outlet Adapter (CC):
pump is supplied with an
adapter to female 1/2 NPT. To connect directly to pump,
remove the adapter and use a medium 3/16-16 UN
medium pressure, coned and threaded connection.
Hydraulic Power Supply
See Typical Installation, page 4.
The hydraulic power supply (V) must have a pressure
reducing valve and a pressure-compensated flow con-
trol.
A flow control valve (R) is required to limit the incoming
flow to the reciprocator to a
maximum of 3 gpm (11 lpm)
.
Hydraulic Lines
Shut-off Valves (H, L):
installed on the hydraulic supply
and return lines. Order Part No. 108537 and 112578.
Drain Line:
Monitor the weepage of hydraulic fluid or
lubricant. If it seems excessive or increases suddenly,
the reciprocator/pump seals may need to be changed.
Hoses:
Use a minimum 1/2 inch supply line (S) and
minimum 3/4 inch return line (F) on the reciprocator.
Contact your Graco representative for details of line siz-
ing.
Pressure Reducing Valve (N):
circulates excess
hydraulic fluid pressure back to the hydraulic power sup-
ply. Install this valve (N) in the hydraulic supply line with
a drain hose (A) teed into the hydraulic return line (F).
Limit supply pressure to a maximum 900 psi (6.2 MPa,
62.1 bar)).
Accumulator (P):
reduces hammering effect caused by
the reciprocator when it reverses direction.
Fluid-filled Pressure Gauge (M), Part No. 112567:
monitors hydraulic pressure to the reciprocator during
startup. See F
. 1. Use the gauge for initial adjustment
of the reciprocator. It can be removed after adjustment.
Mount pump securely so it cannot move around
during operation. Failure to do so could result in per-
sonal injury and/or equipment damage.
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 component ruptures, all
accessories added to the reciprocator power supply
side must have at least 900 psi (6.2 MPa, 62.1 bar))
maximum working pressure.
All accessories added to the pump fluid outlet side
must have at least 10,000 psi (69 MPa, 689 bar)
maximum working pressure.
Limit Fluid Flow to Reciprocator
To reduce the risk of overpressurizing the hydraulic
reciprocator which could cause a rupture and serious
injury, including fluid injection, a hydraulic system
must have a means to limit the incoming fluid flow to
the reciprocator to a maximum of 3 gpm (11 lpm) and
900 psi (6.2 MPa, 62.1 bar).
