Operation and Function of Flux Pump Tubeset F425
When emptying a drum or container, the liquid which remains in the pump tubeset or hose being used with a Flux hand nozzle will always remain under the control of the operator. 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.)
