ABSTRACT:
A gear pump is disclosed having an integrated gear cavity and bearing receptacle that includes a fluid path for lubricating the bearings. The preferred embodiment includes a helical gear pump having a manifold with inlet and outlet ports. The integrated gear cavity and bearing receptacle are located in a one piece molded end cap. The bearing receptacle receives a coupled bearing assembly. Together, the coupled bearing assembly and the bearing receptacle define a supply path outside the bearings along the bearing receptacle and a return path through the bearings so that fluid can pass by, and lubricate, the bearing-axle interface.
