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.
