Canned Motor Pump
The canned pump is a centrifugal pump, close coupled to a canned Motor in such a way that there is no dynamic shaft seal, no couplings and no ball bearings. The motor is cooled by the pumped liquid and sleeve type bearings are lubricated by the same liquid. This eliminates the need for external lubrication.
The Stator of the driving motor, which is usually three phase squirrel cage induction motor, which is hermetically contained in a stator containment that consist of an external frame tube, out board & inboard end plates and the cylinder liner.
The Rotor which is welded on the shaft, is also encapsulated with a non magnetic liner. Both stator can and the rotor can are seal welded at both ends, and does not allow any part of the motor to be exposed to external environment or internal pumped liquid.
