Magnetic driven pumps for hermetically sealed processes
Seal-less pumps for critical media
Magnetic driven pumps combine conventional pump hydraulics with a permanent-magnet drive system and a three-phase motor. The contactless and slip-free torque transmission is achieved via the attractive and repulsive forces between permanent magnets in the two coupling halves. Between them lies the gap ring, which hermetically seals off the product chamber from the surrounding environment.
The hermetic seal is ensured by a single-acting safety casing. Magnetic driven pumps are used in particular for toxic, strong-smelling or otherwise hazardous fluids, as the fluid remains safely shielded from the surroundings by the gap pot.
Advantages
Hermetically sealed
The isolation chamber reliably separates the process medium from the surrounding environment and ensures maximum process safety.
low-wear power transmission
The permanent-magnet coupling transmits torque without contact and without slippage. This reduces wear and maintenance requirements and ensures reliable operation.
Suitable for critical media
Ideal for aggressive, toxic, explosive or highly volatile fluids.
Flexible system integration
Design in accordance with EN 22858, ISO 2858 and ISO 5199, together with the use of standard motors available on the market, enables easy integration into existing systems and system designs.
