RMAK

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.

The RMAK is a custom solution for agitators in refineries and in the chemical, petrochemical, and oil & gas industries. This magnetic coupling is highly customizable and can be designed for high temperature ranges. Further options include the scope of delivery regarding shaft, bearing, housing, cooling flanges and measurement technology.

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.
