Priming Piston Lower Cleaning

15. Stand the pump upright, placing the cylinder

(101) into the base (102). Reattach the clamp
to hold the base (102) to the cylinder (101).
Replace the pin (125).

16. Turn the pump on its side. Use a rubber mallet

to tap the displacement rod so the piston rod
extends well out of the cylinder.

17. Hold the displacement rod (105) with a wrench.

Screw on the guide (119) and use another
wrench to tighten.

18. Install the valve plate (120) and the priming piston

(121). Hand tighten the priming piston nut (122).

19. Hold the displacement rod (105) with a wrench.

Use another wrench to tighten the priming piston
nut (122).

1.

Set the displacement pump in place. Align the
air motor and set it on top of the displacement
pump. Attach the clamp. Replace the pin.

2.

Hold the motor shaft up with one hand. With your
other hand, put the coupling nut (5) on the rod.

3.

Put the coupling collars (5) into the coupling nut
so large flanges point upward.

4.

Gently let the motor shaft drop onto the rod.
Use a spanner wrench to tighten the coupling
nut securely. A Graco spanner wrench tool (p/n
112887) is available.

5.

Connect the remaining air and fluid hoses and
the ground wire.

6.

Circulate the sanitizing solution through the pump
and the system prior to use.
