Lubricate V-Packings
51. Open Valve Screw (21).
52. Place an appropriate collection container underneath
the Valve Seat.
53. Attach a hand gun to Hydraulic Fitting (17).
54. Pump a high quality NLGI 1 or 2 grease* until the
grease is free of air (product if not rebuilt).
55. Close the Valve Screw.
Bench Test and Operation
WARNING
Do not exceed the lowest pressure rating
of any component in the system.
Never point a control valve at any portion of your
body or another person. Lubricant discharged at
high velocity can penetrate the skin and cause
severe injury. Should any fluid appear to puncture
the skin, get medical care immediately.
Ensure all components are in operable condition.
Replace any suspect parts prior to operation.
Should leakage occur anywhere within the system,
disconnect air to the motor. Personal injury can
occur
Initial Start Up
1. Make sure air pressure at the regulator reads zero.
2. Install air Connector (3) to the inlet of the air motor.
3. Connect Air Coupler (4) to the Connector.
IMPORTANT: The pump must begin to cycle
once the air pressure reaches 15 psi (1 Bar).
4. Slowly supply air pressure [not to exceed 15 psi
(1 Bar)] to the pump's motor.
• The pump assembly should begin to cycle.
* Lubricate the V-Packings once again after 8 hours of
operation. Thereafter, lubricate once every 24 hours of
operation.
Revision (2-04)
Medium-Pressure Material Pump
If the pump assembly does not cycle, loosen the
Packing Screw.
NOTE: The pump may not cycle for addi-
tional reasons. Refer to the Troubleshooting
Chart for details.
Should the pump cycle before 15 psi (1 Bar) is reached,
tighten the Packing Screw.
CAUTION
Do not operate the pump longer than 2 minutes
during the adjustment procedure. Excessive heat
due to friction can change the setting.
5. Continue to adjust the Packing Screw until the pump
begins to cycle at 15 psi (1 Bar).
With air pressure at zero:
6. Connect a product hose to the pump's material outlet.
• Direct the hose into a collection container.
7. Place the pump in the product to be dispensed.
8. Slowly supply air pressure to the pump's motor once
again.
9. Allow the pump to cycle slowly until the product is
free of air.
If the pump assembly does not prime, refer to the
Troubleshooting Chart for details.
10. Inspect Packing Screw (12) for leakage.
Should oil (solution) overflow the torque hole in the
Packing Screw, tighten the Packing Screw clockwise 1/8
turn.
With air pressure at zero:
11. Attach a control valve to the outlet hose of the pump.
• Make sure the nozzle on the control valve is open
and pointed into an appropriate collection container.
12. Slowly supply air pressure to the pump's motor.
13. Allow the pump to cycle slowly until the product is
once again free of air.
14. Set the air pressure to 100 psi (6.9 Bar).
15. Operate the control valve into the container
momentarily.
