A pump powered by a canned motor has a removable stator cartridge. One end of a generally hollow pressure housing is secured to a pump housing. An annular stator cartridge is removably secured in the pressure housing. An annular gap between the inner surface of the pressure housing and the outer surface of the stator cartridge defines a flow path for cooling fluid to permit the stator cartridge to be surrounded by cooling fluid. A rotor is operatively positioned inside the stator cartridge to form an electric motor when the stator cartridge is energized. The output shaft of the rotor is connected to an impeller in the pump housing. The rotor is rotatably supported by bearings. An end cap is removably secured to the other end of the pressure housing. Removal of the end cap permits access to and removal of the stator cartridge without requiting removal of the motor from the pump housing.
