eMAK

Features

Magnetic couplings (MAK) are a hermetic, low-maintenance sealing solution for pumps, agitators, and aerators. Dangerous or precious media remains isolated in the closed system circuit. In turn, nothing penetrates to contaminate the medium.

  • For standard applications up to 25 bar
  • Available from stock
  • Single-walled can
  • Product-lubricated sliding bearing included (optional)
  • High performing
  • Energy efficient
  • Highly reliable and maintenance-free

Advantages

With the eMAK, there is now a new efficiency standard for magnetic couplings. A special design in combination with a special can as well as high-performance magnets make this magnetic coupling particularly powerful. This means that pumps, for example, can be built much more compactly. The eMAK is specially designed for standard applications up to 25 bar and is available from stock.

  • Hermetically sealed / leakage-free
  • High-strength, corrosion-resistant can made of Inconel®
  • High-performance magnets of Samarium cobalt
  • Maintenance-free in trouble-free operation
  • Product lubricated sliding bearing (optional); no need for a supply system
  • Easy switch to the new eMAK series
  • Available from stock
  • Special configuration tool (online) for easy seal design

Functional description

Power is transmitted contact-free by magnets from the drive shaft to the product-contacting output shaft. Between the two rotating parts is the containment can, the sealing element, which is bolted to the container. It separates the product space from the atmosphere and hermetically seals it statically.
