ABSTRACT:
A submersible centrifugal pump is disclosed. It includes a housing with a linear stack of axially mounted pumping units therein. Each unit is constructed as a module with at least a first and a second impeller mounted to a central shaft. A diffuser forms an outer casing which is provided for each impeller. A thrust bearing, lubricated and cooled by the fluid being pumped is supported from and to the outer casing and is arranged to receive axial force from the upstream impellers in each modular unit. A plurality of impellers and diffusers can form a single modular unit.
