Advanced Fluid Movement Technology: Gerotor Manufacturing

What is a Gerotor?

A gerotor is a positive displacement device that consists of an inner rotor and an outer rotor. The term "gerotor" is derived from "generated rotor."

Gerotors are unique in that the inner rotor has one less tooth than the outer rotor. As the inner rotor turns within the outer rotor, the space between the gears changes, allowing the device to draw in and expel fluids or gases. This design ensures smooth, pulse-free flow with minimal noise and vibration.

Gerotor Pumps

Gerotor pumps leverage the principles of the gerotor design to transport fluids. They function by using the varying space between the inner and outer rotors to create chambers. As the rotors turn, these chambers grow on the intake side, drawing fluid in, and shrink on the discharge side, pushing fluid out.

The result is a continuous, smooth flow of fluid. Due to their efficiency, gerotor pumps are commonly used in various applications, including automotive oil pumps, hydraulic systems, and fuel transfer systems.
