The pump is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing. The bearings are lubricatd by the pumped liquid.
In order to avoid problems in connection with disposal, great importance has been attached to using as few different materials as possible. The pump is characterized by:
3 speed motor.
Ceramic radial bearings.
Carbon axial bearing.
Stainless steel rotor can, bearing plate and rotor cladding.
Aluminium alloy stator housing.
Cast iron pump housing.
Stator with built-in thermal switch.
The motor is a 3-phase motor.
The pump is supplied with a standard module in the terminal box. The standard module is to be connected to the mains supply via external contactor.
