Description

The QPM3 gerotor type of low pressure pump is equipped with
electric motor, double bearing shaft and flexible coupling.
The gerotor principle is based on an inner and an outer rotor. The
inner rotor has one less tooth than the outer. The inner rotor has
its centreline positioned at a fixed eccentricity from the centreline
of the outer rotor. As the rotors rotate about their own respective
axes oil is drawn into the enlarging chamber. The process occurs
constantly for each chamber, providing a smooth pumping action.
QPM3 low pressure pump comes as standard with pump flow
10, 20, 40, 60 and 80 l/min.
