ABSTRACT:
A pump drive apparatus comprises a housing (1) that accommodates a shaft (2) and a pump impeller (3). Both rotate around the same axis (4). The impeller rotates against the housing on at least one bearing (5). There is an eccentric journal (6) on the end of the shaft inside the impeller. The journal rotates in an orbital journal bearing (7). The orbital journal bearing moves in a circle within an eccentric bearing 14 on the impeller, driving the impeller. The orbital bearing tightly encloses the journal. A flexible component (9) prevents the orbital bearing from rotating in, and seals it off from, the housing.
