Hermetic - Model CN -Single Stage Canned Motor Pump

Canned motor pumps are characterised by a compact, integrated unit without mechanical seal. The motor and  pump form a unit with the rotor and the impeller fitted onto a common shaft. The rotor is guided by two identical, liquid-lubricated slide bearings. The stator winding of the motor is separated from the rotor chamber by means of a thin stator liner. The partial flow for cooling the motor and lubricating the slide bearings will be deverted at the periphery of the impeller and, after having passed through the motor, is recirculated through the hollow shaft to the suction side of the impeller. This design is suitable for the delivery of uncritical liquids at low vapour pressures.
