 OPERATION
AND FUNCTION OF FLUX PUMP TUBESET-- F425.
When emptying a drum or container, the liquid which remains in the
pump tubeset or hose should NOT be allowed to flow back into the drum
or container, but remain under the control of the operator. Therefore,
the pump tubeset--model F425-- is equipped with an integrated back-flow
stop in the lower part of the pump housing, which is operated manually
by turning an adjustable lever 90 degrees to a locked position. As
soon as the drum or container is completely empty and no more liquid
is being discharged, the integrated back-flow stop MUST be closed
with the motor still running. In that way, any back-flow of the liquid
is prevented and ensures that the drum or container is emptied to
its maximum.
ADVANTAGES of Flux pump

- Drums and containers can be emptied
in vertical position up to one (1) pint and in tilted position

at the bottom of the tubeset, the liquid in the pump and transfer
hose cannot flow back into the drum or container.
- When the union nut on the lower
side of the motor is unscrewed, the motor can be removed, then
the inner tube can be pulled out of the outer tube.
- Pump tubeset F425 S in stainless
steel has an outer diameter of ony 1 19/32" over the total effective
immersion length. F425 P outer diameter is 2".
