The pump is designed with a radial fluid inlet and a radial outlet arranged on the
same axis. The impeller is rigidly connected to the motor shaft.
The motor housing is equipped with a terminal box. Mechanical sealing is not
required as the rotating assembly is completely isolated from the stator winding. The
rotating assembly is lubricated and cooled by the fluid pumped. The advanced
lubricating system and precision-balanced impeller ensure smooth running and a
long service life.
The fluid enters the pump via the suction nozzle and is accelerated outward in a
cylindrical flow by the rotating impeller, which is driven by the motor shaft. In the
flow passage of the pump casing the kinetic energy of the fluid is converted into
pressure energy. The fluid is pumped to the discharge nozzle, where it leaves the
pump.
