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.
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.
The pump is available in:
Fluid temperature range:

* 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.
