The pump housing is closed off with a screwed front cover in order
to avoid the risk of injury.
The motor serves to drive the rotor. Two shoes at the ends of the
rotor serve to press the pump hose against the pump housing.
The rotary movement of the rotors alternately press and relax the
shoes in relation to the pump hose. This serves to suck the media
in and convey it into the metering line.
