Starting and Adjusting the Pump
1. Be sure the pump air regulator (BE) is closed. Set
the ram air regulator (BB) to about 50 psi (0.35
MPa, 3.5 bar). Set the director valve (BC) to DOWN.
2. Start the pump as explained in the separate pump
instruction manual.
3. Keep the director valve (BC) set to DOWN while the
pump is operating.
Adjusting the Pressure
Different combinations of seal and ram pressure may be
necessary for proper seal and pump operation.
•
If the pump does not prime properly with heavier
fluids, increase air pressure to the ram.
•
If fluid is forced out around the inflatable seal,
decrease pressure to the ram.
•
For diaphragm pump models, adjust DOWN
pressure to the minimum level, to ensure that the
pump inlet balls seat properly.
If seal pressure builds when the seal enters a tapered
portion of the drum, the relieve valve will activate. Turn
the seal bleed-off valve (BL) counterclockwise to open
it.
