Principle: Complete drum drainage RE

The closing is carried out by a small lever below the hand wheel. A movable sealing cap locks the pump foot and prevents the entered liquid from flowing back into the drum. With the motor is switched off, the pump tube holding the liquid can be removed and inserted into the next drum.

	Sealing cap is open- the liquid is pumped out
	Sealing cap is closed- prevents a return flow when pump is removed.
