MMB-L SERIES
The MMB-L series is a range of magnetically coupled centrifugal pumps in thermoplastic. The series is suitable for applications where traditional pumps with shaft seals may cause issues, and increased safety with a 100% leak-proof pump is desired. The magnetically coupled design, where the motor power is transmitted to the impeller using a magnet, eliminates the risk of leaks due to worn or faulty shaft seals. The pump casing is constructed with extra thickness to achieve additional strength and operational reliability.
Material Combinations
With pump casing in PP or PVDF and gaskets in EPDM-FPM-FEP or FFKM, the MMB-L series is highly suitable for pumping strong acids and bases. The series is usually supplied with partially open impellers, but can also be provided with closed impellers for clean or hot fluids.
Accessories and Additional Equipment
• Drain connection
• Self-priming tank

Technical structure and benefits
- Pump housing in extra-strong PP or PVDF, machined for size 65-125 and 65-160. Models 25-125, 32-125, 40-130, 40-160, and 50-160 have precision-cast pump housings
- Impeller in PP or PVDF; partially open impeller for particle-laden media and closed impeller for clean media. Axially balanced impeller with blades on the back
- Rotor in PP or PVDF with a central hole for lubrication of the rear bushing and for balancing the impeller. Fully encapsulated magnets in thermoplastic for maximum protection
- Guide bushing in PTFE CG (SiC on request), rotates with the rotor
- External magnetic core rotates with the motor and transfers torque to the rotor. Loose flanges in glass fiber reinforced PP, reinforced with a metal core
- Loose flanges in glass fiber reinforced PP, around a steel core
- Robust intermediate flange in G25 and base mounting
- Static guide bushings in SiC (Al2O3 on request)
- Three-phase asynchronous motor according to IEC (NEMA on request)
