Operation/Maintenance

Starting and Adjusting the Pump

See the Typical Installation on page 5. Be sure the air regulator (E) and bleed--type master air valve (D) are closed. DO NOT INSTALL THE SPRAY TIP YET!

Connect a suction hose (N) to the pump’s fluid inlet. Hold a metal part of the spray gun (M) firmly to the side of a grounded metal pail and hold the trigger open. Then open the pump’s bleed--type master air valve (D). Now slowly open the air regulator until the pump starts, about 40 psi (0.9 MPa, 2.8 bar).

Cycle the pump slowly until all the air is pushed out and the pump and hoses are fully primed. Release the spray gun trigger and lock the safety latch. The pump should stall against pressure when the trigger is re- leased.

Follow the Pressure Relief Procedure on page 8, then install the spray tip in the gun.

With the pump and lines primed, and with adequate air pressure and volume supplied, the pump will start and stop as the spray gun is opened and closed. In a circulating system, the pump will run continuously and will speed up or slow down as supply demands until the air supply is shut off.

Use an adequately sized air regulator (E) to control the pump speed and the fluid pressure. Always use the lowest air pressure necessary to get the desired results. Higher pressures waste fluid and cause pre- mature wear of the pump packings and spray tip.

WARNING

To reduce the risk of overpressurizing your system, which could result in component rupture and cause serious bodily injury, NEVER exceed the maximum incoming air pressure given on your pump or in the Technical Data on pages 22--23.

Keep the packing nut/wet-cup (2) filled with Graco Throat Seal Liquid (TSL) or compatible solvent, to help prolong the packing life. Adjust the packing nut weekly so it is just tight enough to prevent leakage; do not overtighten. See Fig. 3. Always follow the Pressure Relief Procedure on page 8 before adjusting the packing nut.

Never allow the pump to run dry of the fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. A pump runaway valve (B), which shuts off the air supply to the pump if the pump accelerates beyond the pre--set speed, is available. See the Typical Installation on page 5. If your pump accelerates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, refill the container and prime the pump and the lines with fluid, or flush and leave it filled with a compatible solvent. Be sure to eliminate all air from the fluid system.

Shutdown and Care of the Pump

For overnight shutdown, follow the Pressure Relief Procedure on page 8. Always stop the pump at the bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and damaging the throat packings.
