Magnetically coupled centrifugal pumps Type RM 2.1

Magnetically coupled centrifugal pumps of building group 2.1 are 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.

Magnetic drive pump - Type RM 2.1

Constructional design

Housing, impeller magnet coating and rear casing can be made of either PPS* 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). *Impeller made of PPS. **Ceramic impeller.
