Magnetically coupled centrifugal pumps of building group 1 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 are made of either glass-fibre reinforced PP plastic or PVDF or stainless steel. 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 or EPDM or FEP (optionally available).
The pump is available in:
PP, PVDF, stainless steel
Pump sizes 2/20 | 3/30 | 5/35

* 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.
