Operation
Pressure Relief Procedure
WARNING
To reduce the risk of serious injury, including
splashing fluid in the eyes or on the skin, follow this
procedure whenever you are instructed to relieve
pressure, when you shut off the pump, and before
you check, adjust, clean, move, or repair any
system equipment.
1. Shut off the air to the pump.
2. Open any available outbound fluid valves to relieve
fluid pressure from the pump.
3. If fluid is still in the outbound fluid lines, isolate this
fluid as follows:
a. Close the outbound fluid valves.
b. Slowly remove the fluid connections from the
pump, and have a container ready to catch
any fluid that runs out.
Flush the Pump Before First Use
The pump was tested in water. If water could
contaminate the fluid you are pumping, flush it
thoroughly with a compatible solvent. Follow the
procedure in Starting and Adjusting the Pump.
Starting and Adjusting the Pump
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 the
pump is dropped, the fluid section could rupture.
Always follow the Pressure Relief Procedure
above before you move or lift the pump.
1. Be sure the pump is properly grounded. Read and
follow the instructions in Grounding 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.
3. Place the suction tube (if used) in the fluid to be
pumped.
NOTE: If the 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.
4. Place the end of the outlet hose into an
appropriate container.
5. Close the fluid drain valve.
6. With the air regulator closed, open all bleed-type
master air valves.
7. If the outlet hose has a dispensing device, hold it
open while continuing with step 8.
8. Slowly open the air regulator 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.
If you are flushing, run the pump long enough to
thoroughly clean the pump and hoses, close the
air regulator, and remove the suction hose from
the solvent and place it in the fluid to be pumped.
If you are shutting down the pump, remove the
suction hose from the fluid container, run the pump
until the fluid is forced out of the system, and shut
off the air supply immediately.
If you are going to use the pump, start the pump
again, and place the suction hose in the supply
container.
Pump Shutdown
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 whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure at left.
