RM BG 2D | RM BG 3

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.

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.
