P R O D U C T I N F O R M A T I O N Multistage canned motor pumps Model series CAM/ CAM-Tandem Contents Description Description 2 General Canned motor pumps are characterised by a compact, Application and insertion 4 integrated unit without mechanical seal. The motor and pump form a unit with the rotor and the impeller fitted Functional principle and materials 5 onto a common shaft. The rotor is guided by two identical, medium-lubricated slide bearings. The stator on the drive Design options 11 motor is separated from the rotor space using a thin stator liner. The rotor cavity itself, along with the hydraulic section Monitoring systems 13 of the pump, create a combined cavity which needs to be filled with pumping medium before commissioning. Characteristics diagramm 14 The heat loss from the motor is carried off by a partial flow between the rotor and the stator. At the same time, the partial flow lubricates both slide bearings in the rotor cavity. Both the can, which is a hermetically sealed component,
