SMAK

Merkmale

Magnetic couplings of the SMAK series are used to transfer torque into mixers and agitators. Top drive, bottom drive or lateral drive. Dangerous or precious media remain isolated in the closed vessel.

Vorteile

  • Magnetic coupling for mixers and agitators
  • Hermetically sealed
  • Sterile design
  • Parts in contact with the medium are electro-polished
  • No contamination by buffer media
  • No contact of torque transmitting elements
  • No maintenance necessary
  • Sliding bearing for bottom drives included
  • Speed monitoring optional
  • Weld-in or screw-in flanges available
