It is hard and complex to analytically derive a formula for the volumetric-displacement of a Gerotor pump. An analytical method on the simple formula for calculating volumetric-displacement of a Gerotor pump is proposed in this work, which is relative easy and based upon using length of rotary teeth. The rotary teeth lengths mean the distances from axis of inner rotor or outer rotor to conatact points between inner and outer rotors. The proposed formula is verified through comparison with volumetric-displacement obtained from numerical CAD calculation.
