Operation

WARNING

COMPONENT RUPTURE HAZARD To reduce the risk of overpressurizing your system, which could cause compo- nent rupture and serious injury, never

exceed the specified Maximum Hydraulic Input Pressure to the pump (see the Technical Data on page 15).

To prevent overpressurizing the hydraulic motor or its seals, always shut off the supply line valve (S) first, then shut off the return line valve (E).

Starting and Adjusting the Pump

WARNING

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

NOTE: If the pump is not immersed in fluid, fill the wet-cup (P) 1/3 full with Graco Throat Seal Liquid (TSL) or a compatible solvent, to prevent fluid from drying on the displacement rod and damaging the pump packings. Refer to the Typical Installation on page 7. Check the tightness of the packing nut/wet- cup weekly. Before adjusting, relieve the pressure. The nut should be tight enough to prevent leakage, but no tighter.

Check the hydraulic fluid level, and add fluid as neces- sary to the fill lines, before each use. Turn on the hydraulic power supply. Open the return line shutoff valve (E). Slowly open the hydraulic supply shutoff valve (S). Run the pump slowly until all air is pushed out of the lines and fluid is flowing smoothly. Close the spray gun; the pump will stall. Use the lowest pressure possible to get the desired results. Higher pressures will cause premature tip and pump wear.

NOTE: In a direct supply system, the pump starts and stops automatically when the spray gun is opened and closed. In a circulating system, the pump runs continu- ously, speeding up or slowing down as the spray gun is opened or closed, until the hydraulic power supply is turned off.

CAUTION

Never allow the hydraulic oil temperature to exceed 130_ F (54_ C). The pump seals will wear faster and leaking may occur at higher temperatures.

WARNING

To reduce the risk of overpressurizing the system, always follow these precautions:

Never exceed 1500 psi (10.3 MPa, 103 bar), or

10 gpm (37.8 liter/min) hydraulic input to the motor.

Never exceed 1000 psi (7 MPa, 69 bar) maximum pump outlet pressure.

Check Valve Adjustment

The fluid piston and intake valve are factory set for high-volume pumping of heavy, spray-viscosity fluids. To adjust the check valves, refer to the operation section in the separate displacement pump manual.
