Abstract
A fluid pump system comprises an electrical drive unit and a rotary pump comprising a rotatable shaft and a drive element formed from a number of impellers attached to the shaft for causing flow within a process fluid. The electrical drive unit comprises an electrical stator and an electrical rotor attached to the shaft via a coupling, the electrical stator being disposed adjacent to the electrical rotor. The electrical stator is disposed within a first casing and the rotary pump and the electrical rotor are disposed within a second casing. The first casing contains a first fluid and the second casing contains a second fluid.
