ABSTRACT:
An eccentric worm pump has a tubular stator extending along a main axis and having an intake side and an output side, an eccentric worm fitting in the stator and centered on a rotor axis offset from the main axis, an intake housing forming an intake compartment opening into the intake side, a connecting shaft extending along the main axis from the rotor through the intake compartment, and a drive shaft extending along the main axis from the connecting shaft out of the intake compartment. The rotor, connecting shaft, and drive shaft are unitarily formed of plastic. A seal housing mounted on the intake housing seals around the drive shaft. A drive connected to the drive shaft rotates the drive shaft, connecting shaft, and rotor about the axis to draw fluid through the stator from the intake side to the output side thereof.
