Magnetically coupled centrifugal pumps – Always on the safe side
Whether acids or alkalis – MAGSON is the perfect solution for pumping highly aggressive media. To safely operate conventional centrifugal pumps with wear-prone shaft seals requires a high technical and financial effort, especially for highly aggressive or crystallizing media.
The regular maintenance cycles required also reduce the availability of the system.
The advantage of seal-less, magnetically coupled centrifugal pumps: hermetically sealed and maintenance-free
The externally rotating drive magnet transmits the motor power contactless to the inner magnet and thus to the impeller (see diagram below). This means that there is no need for a continuous shaft and consequently no wearing shaft seal towards the motor. Pump chamber and drive are hermetically separated from each other by a can.
Leaks are excluded, the pumps are maintenance-free.

Magnetic Drive Pumps in PP/ETFE (9)
Maximum security
- no shaft seal, therefore hermetically sealed
- best chemical resistance through ETFE (better than PVDF)
- Thermal protection on AC motors prevents damage from motor overload
- Motor change possible with closed system (from BG4)
- Self-priming variant MAS for conveying particularly critical media, for example from double-walled tanks from above
Maximum efficiency
- from BG4 volute housing for best efficiency and particularly low energy consumption
- additional efficiency through optimized liquid flow on the suction side (from size 4)
- competent advice for an optimal design of the MAGSON for your application
- Motors also available with frequency converters for a constantly optimal operating point
Maximum reliability
- robust construction
- Coating inner magnet in PP without glass fiber for higher durability
- special suction-side liquid flow counteracts cavitation (from size 4)
- Axle mount with rinsing to cool the plain bearing (from size 4)
Minimal life cycle costs
- low operating costs due to particularly high efficiency
- maintenance free
- Plain bearing with plastic coating protects the bearing seat from overheating in the event of insufficient lubrication (from size 4)
- low repair costs because the axle mount can be replaced in the housing (from size 4)
- low downtimes and minimal effort when replacing the motor thanks to the back-pullout design (from size 4)
- Less effort for stocking spare parts thanks to the modular system
Maximum flexibility
- ETFE available as a universal material for acids and alkalis
- Loose flanges and thread adapters for flexible connection options (both standard from BG4)
- IEC standard motors for quick availability worldwide
- Three-phase motors with PTC thermistor for frequency converter operation as standard
- short delivery times thanks to the modular system
