Design
The pump is designed with a radial fluid inlet (suction nozzle) and a radial fluid
outlet (discharge nozzle) arranged on the same axis. The impeller is rigidly connected
to the motor shaft. 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 handled. The electronic system housing is equipped with a plug-
type connector. Depending on the design the pump set is fitted with high-quality
ceramic bearings or carbon bearings, ensuring smooth running and a long service
life. The integrated continuously variable differential pressure control and electronic
control unit enable an optimum adjustment of the pump to changing operating
conditions and minimise operating costs. The combination of the hydraulic system
with a high-efficiency electric motor makes sure that the input power is converted
into hydraulic energy as efficiently as possible.
Function
The fluid enters the pump via the suction nozzle (12) and is accelerated outward in a
cylindrical flow by the rotating impeller (10). In the flow passage of the pump casing
the kinetic energy of the fluid is converted into pressure. The fluid is pumped to the
discharge nozzle (7), where it leaves the pump. The pump rotor (9) runs in radial
plain bearings (8). The radial plain bearings (8) are supported by the stator (11).
