Canned motor pump
The canned motor pump is a centrifugal pump designated according to the nature of its drive. It is a sealless pump which is made of a highly corrosion-resistantmaterial and is absolutely maintenance-free.
See Fig. 1 Canned motor
Permanently excited synchronous motors (see EC motor) are particularly efficient drives for canned motor pumps. The use of permanent magnets in the rotor allows losses (excitation losses) to be minimised. Leckage is contained in the flameproof enclosure of the motor.
