3.0 OPERATION
3.1 Start up and adjustment of transfer pump
1. Ensure that the air control valve is closed then open the bleed-type master air valve.
Connect the quick disconnect coupler to the male fitting.
2. For safety, open the dispensing valve slowly, then drain fluid into a grounded metal
container. Ensure metal-to-metal contact is maintained between the container and the
valve at all times.
3. Adjust the air control valve slowly for just enough pressure to start running the pump.
This is to prime all air within the system. After all the air has been expelled from the
lines, close the dispensing valve. During the priming of the pump, the pump operates
when the dispensing valve is opened and stops when the valve is closed.
4. Turn the air regulator slowly until sufficient flow from the dispensing valve is achieved.
Remember to always run the pump at the lowest possible speed necessary to achieve
what is desired. Never exceed the maximum working pressure of any component in
the system.
5. The pump should not be left to run dry of the fluid being worked upon. When running
empty, the operating speed will rise rapidly, increasing the chance of damage to the
pump and/or components. During operation should the pump be found to run too fast,
stop it immediately and ensure the fluid supply is not too low or the drum is empty. If
air has gone into the system, repeat the priming procedure. Ensure that all air has
been expelled from the lines before beginning operation again. Flush the pump or
leave it filled with a compatible solvent when not in use.
6. Always follow the Pressure Relief Procedure should the pump be put away for any
period of time or during system shut off at the end of the day.
3.2 Shut down procedure
1.
Relieve the air pressure with the air regulator.
2.
Open the air needle valve.
3.
Bleed off residual pressure in the system with the bleed-off master air valve.
4.
Open the drain valve to relieve fluid pressure in the system. Use a container to
collect the fluid drained off.
Be especially careful as the fluid may still be under
pressure
. Hold the metal fluid drain valve against the side of the grounded
container while relieving the pressure.
Note: For long periods of shut-down, flush the pump thoroughly with an
appropriate cleaning fluid to prevent solidified chemical build-up.
