Function:
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 centre-line positioned at a fixed eccentricity from the centre-line 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.

A small selection of part numbers have been included however for more options and information please download the QPM3 brochure or contact your local Parker sales office.
