Operation
Starting and Adjusting the Pump
All Systems
1.
Be sure the pump is properly grounded. Read and
follow FIRE AND EXPLOSION HAZARD, on page 4.
2.
Check all fittings to be sure they are tight. Be sure to
use a compatible liquid thread sealant on all male
threads. Tighten the fluid inlet and outlet fittings
securely.
NOTE: If the fluid inlet pressure to the pump is more than
25 percent of the outlet working pressure, the ball check
valves will not close fast enough, resulting in inefficient
pump operation.
NOTE: If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses. Close the air
regulator. Remove the suction tube from the solvent and
place it in the fluid to be pumped.
Waste Oil Receiver Evacuation Systems, or General
Fluid Transfer Applications (see Fig. 2)
1.
Close the pump air regulator (C) and all bleed-type
master air valves (B, E).
2.
Connect the pump suction hose (G) to the pump fluid
inlet. Attach a fluid quick coupler (H) to the other end
of the hose, then connect the coupler to the outlet
fitting of the waste oil receiver (M).
3.
Place the end of the fluid hose (L) into an appropriate
container.
4.
Close the fluid drain valve (J). Open the fluid shutoff
valve (K).
5.
Connect the air side quick coupler (D) to the pump air
inlet fitting.
6.
Open all bleed-type master air valves (B, E).
7.
Slowly increase air with the air regulator (C) until the
pump starts to cycle. Allow the pump to cycle slowly
until all air is pushed out of the lines and the pump is
primed.
8.
Adjust the air regulator. Do not use higher air pressure
than necessary for the pump to provide good suction.
Increasing the pump cycle rate does not necessarily
improve suction.
Gear Oil Evacuation Systems (see Fig. 3)
1.
Close the pump air regulator (C) and all bleed-type
master air valves (B, E).
2.
Attach an appropriate wand (S) to the suction hose
(P). Place the wand in the differential or fluid to be
pumped.
3.
Place the end of the fluid hose (L) into an appropriate
container.
4.
Close the fluid drain valve (J). Open the fluid shutoff
valve (K).
5.
Connect the air side quick coupler (D) to the pump air
inlet fitting.
6.
Open all bleed-type master air valves (B, E).
7.
Set the air regulator (C) to about 50 psi (3.5 bar).
8.
Pull the control valve handle (R) down to start the
pump.
9.
Adjust the air regulator. Allow the pump to cycle
slowly until all air is pushed out of the lines and the
pump is primed. Do not use higher air pressure than
necessary for the pump to provide good suction.
Increasing the pump cycle rate does not necessarily
improve suction.
10. Push the control valve handle (R) up when finished.
Place the wand (S) in the holder on the control valve.
NOTE: Be sure the control valve handle (R) is closed
when evacuation is completed. Failure to close it may
prevent other service bays from developing full suction.
Pump Shutdown (All Systems)
At the end of the work shift and before checking, adjusting,
cleaning, or repairing the system, relieve the pressure.
WARNING
To reduce the risk of serious injury, splashing in the eyes
or on the skin, and toxic fluid spills, never move or lift a
pump under pressure. If dropped, the fluid section may
rupture. Always follow the Pressure Relief Procedure
on page 11 before moving or lifting 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 11.
