| Magnetically coupled
centrifugal pumps of building group
2D are non-self-priming
centrifugal pumps with volute casing. They operate in
horizontal position and are built in monobloc design.
A magnetic coupling connects the pump to the electromotor
and transmits the power of the motor to the impeller.

 Constructional design |
Housing, impeller, impeller magnet coating and rear casing can be made of either glass-fibre reinforced PP plastic or PVDF. Sleeve bearings, starting ring and centering shaft are made of 99.7% pure oxide ceramic. O-ring sealing of the housing is made of FPM, EPDM or FEP (optionally available). The pump is equipped with a non-ventilated motor with two shaft ends. A pump head of size 8/60-30 is mounted to each side of the motor. The pump heads may also be connected in series to increase discharge pressure.

To deliver liquids with a higher relative density, we also offer all our pumps with smaller impeller diameters which, however, reduce delivery rates and heads of the pumps. If in doubt, please consult us. |
| ** |
Maximum system pressure depends on the temperature of the fluid delivered. |
