Maximum Working Pressure of Accessories

To reduce the risk of serious injury including fluid injec- tion 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 600 psi (4.1 MPa, 41 bar) maximum working pressure.

All accessories added to the pump fluid outlet side must have at least 7500 psi (51 MPa, 517 bar) maxi- mum working pressure.

Pump Accessories

NOTE: The reference letters in the following descrip- tions, refer to the reference letters used in FIG. 2, page 6.

Follower Plate (A): Place follower plate on grease and rotate while pressing firmly to level material. Order part number 247700 for 60# and 90# automatic lube pump modules; 247701 for 120# refinery reservoir; or 247702 for 400# refinery reservoir.

Pump Outlet Drain Valve (D): Helps relieve fluid pres- sure in pump when pump is shut off. Install valve close to pump fluid outlet. Order valve, Part No. 111229.

A pump outlet drain (D) is required in your system. This valve helps relieve pressure in the displacement pump and hose when shutting down system and in case of a clogged outlet hose. Install valve close to pump outlet.

Hydraulic Power Supply

See FIG. 2. page 6.

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 600 psi (4.1 MPa, 41 bar). See description below.

The hydraulic power supply system (U) must have a pressure reducing valve and a pressure-compensated flow control. A flow control valve (Q) 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 (R) and minimum 3/4 inch return line (F) on the reciprocator. Contact your Graco representative for line sizing.

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 (W) teed into the hydraulic return line (F). Limit supply pressure to a maximum 600 psi (4.1 MPa, 41 bar).

Accumulator (P): Reduces hammering effect caused by the motor when it reverses direction.

Fluid-filled Pressure Gauge (M), Part No. 112567: Monitors hydraulic pressure to the reciprocator during startup. See FIG. 2. Use the gauge for initial adjustment of the reciprocator. It can be removed after adjustment.

NOTE: Pressure gauge (M), pressure reducing valve

(N)and a flow control valve (Q) are included in the Hydraulic Fluid Control Kit 247538 or 247705, which can be ordered separately.
