Functional description

5.1  Drive unit

The metering pump is an oscillating diaphragm pump, the stroke length of

which can be adjusted. An electric motor drives the pump.

5.2  Liquid End

The heart of the liquid end is a highly resistant piston (4) made from

coated stainless steel. The suction valve (1) closes as soon as the piston

(4) is moved in to the dosing head and the feed chemical flows through the

discharge valve (3) out of the dosing head. As soon as the piston moves in

the opposite direction, the discharge valve (3) closes due to the negative

pressure in the dosing head and fresh feed chemical flows through the

suction valve (1) into the dosing head.
Use the flushing collar (6) to flush the sealing surface of the piston.
