Abstract
A gear pump comprises a housing having an inlet and an outlet. A first and second gear each have gear teeth which are in engagement with each other. The first gear is a rotor gear which is journaled within the housing and is drivable. It includes means for driving the first gear in order to move relative to the second gear, such as to pump a fluid from the inlet to the outlet of the housing. The housing includes inner housing parts encasing the gears and a single piece mold around the inner housing parts enclosing the gear pump.
