The pump output is delivered through the impellers and diffusers arranged one behind the other to the pressure nozzle and in this way an increase in pressure is achieved depending on the number of stages. The partial flow for cooling the motor and lubricating the slide bearings is tapped off on pressure side after the last impeller and after flowing through the motor is lead out again through the hollow shaft between the stages. Since, as a result, no heated part of the delivery flows back to the suction side considerably more stable NPSH values are produced in the part load range. Aggregates of multistage design can therefore be used for considerably smaller pumping capacities, than pumps of single-stage design.
