ABSTRACT:
A submersible centrifugal pump (10) includes a casing (11) which houses a motor (13) and a pump assembly (14). A shaft (12) which carries the impeller (37) portion of the pump assembly (14) is driven by the motor (13) to draw fluid, in which the pump (10) is immersed, into the casing (11) in one embodiment through inlet ports (38) to be transferred to the pump assembly (14) and thereby pumped to a remote location. The shaft (12) has an axial bore (40) therein which is open at the bottom (41) to receive fluid. That fluid moves upwardly within the shaft (12) and passes out through radial bores (43) to join with the fluid received from the inlet ports (38). As such, internal fluid positioned in a chamber (23) is cooled by the fluid passing through the shaft (12) and that internal fluid in turn maintains the components in the casing (11) cool. In another embodiment, a submersible centrifugal pump (50) has inlet ports (51) formed near the top of its discharge bowl (15). The inlet fluid travels in axial passageways (52) to the inlet side of the pump assembly (14).
