Type RM 3.1
Magnetically coupled centrifugal pumps of building group 3.1 are self-primingcentrifugal 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 rings and centering shaft are made of 99.7% pure oxide ceramic. The impeller starting ring is made of PTFE graphite. O-ring sealing of the housing is made of FPM or EPDM or FEP (optionally available).

* 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.
