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 eccentri-
city 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.
