Gerotor Pump Design:

A Gerotor Pump is a type of Positive Displacement Pump with 2 gears sets, one inside the other. As the gears rotate, the diverging teeth create an expanding volume which sucks in fluid. The fluid is then transported in the space in between the gears and expelled as the teeth merge.

Advantages:

Positive displacement, Good suction performance

Application:

Transmissions, hydraulics, fluid transfer.
