4 Stator 8 Plug-type connector for power supply
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 pump rotor (5). 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 lubricating system ensures smooth running and a
long service life.
Function The fluid enters the pump via the suction nozzle and is accelerated outward in a
cylindrical flow by the rotating impeller. In the flow passage of the pump casing (7)
the kinetic energy of the fluid is converted into pressure. The fluid is pumped to the
discharge nozzle, where it leaves the pump.

WARNING
Hot surface
Risk of burns
▷Never touch a pump set when it is in operation.
WARNING
Impermissible loads acting on the pump nozzles
Risk of burns by hot fluids escaping!
▷Do not use the pump as an anchorage point for the piping.
▷Anchor the pipes in close proximity to the pump and connect them without
transmitting any stresses or strains.
▷Take appropriate measures to compensate for thermal expansion of the piping.
CAUTION
Contamination/dirt in the piping
Damage to the pump!
▷Flush the piping prior to commissioning or replacing the pump. Remove any
foreign matter.
NOTE
Installing check and shut-off elements in the system is recommended, depending on
the type of plant and pump. However, such elements must not obstruct proper
drainage or hinder disassembly of the pump.
