Abstract

The pump includes gerotor-type pumping means (142, 144), Fig. 2, driven by an electric motor (20) lodged therewith in a common casing (12), the armature shaft of the motor having a portion (64) adjacent a liquid outlet (250), which portion is supported by a self-aligning bearing bush (340) Fig. 10, or (340a), Fig. 10A. Rotation of the bush with the shaft portion is prevented by means e.g. a slot (348a) in the bush loosely engaging with a fixed key (348b), interconnecting the bush and material circumjacent a bore (344) accommodating the bush. A shoulder may be formed on the bush, Fig. 10A.
