Centrifugal Pump | Renner RM 3 Centrifugal Pump | Flux Renner Pumps

Renner, Magnetically, Coupled, Centrifugal, Pumps, Type, RM 3, Flux PumpsMagnetically coupled centrifugal pumps of building group 3 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 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).

  • For aggressive and neutral liquids

  • For short-term and continuous operation

The pump is available in:

  • PP, PVDF, stainless steel

  • Pump sizes 10/120 | 12/150 | 14/180 | 16/200 | 20/200 | 23/200


  • 230/400V three-phase motor, 370 to 1500 watts, 50 Hz, insulation class F, protection class IP 55 motor speed 2,900min-1
    – Other voltages and frequencies are available on request. –
