RMAK
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 agitators and mixers with top, bottom and side entry drive
- Customized solution
- Compact design
- Available with single- and double walled can
- High temperature version possible
- With sliding or roller bearing
Advantages
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, to name just one example. Further options include the scope of delivery regarding shaft, bearing, housing, cooling flanges and measurement technology (speed, temperature monitoring, vibration monitoring).
- Hermetically sealed / leakage-free
- High customizable
- Maintenance-free in trouble-free operation
- FDA compliant materials

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.
Notes
Different variants are available to meet specific requirements:
- Coolable/ heatable bearing arrangements
- Sliding bearings for bottom or side entry drives
- Heating/cooling flange
- Vertical drive with roller bearing (dry running, permanently lubricated)
- High temperature version (+350 °C)
- Sensors for temperature, speed or vibration monitoring
