Magnetically coupled

In contrast to the standard pump, these products have a frictionless magnetic coupling. Oil leakage from a wear-prone conventional shaft seal is ruled out in these models

Applications

  • Installation in analyzers
  • Installation in flywheels
  • Gas technology

Customer value

  • Space-saving and ideal for systems integration
  • High pumping speeds with small dimensions
  • Low ultimate pressure
  • Low-maintenance, no oil leaks from the shaft feedthrough
  • Low operating costs, not necessary to replace shaft seals

Duo 1.6 M

  • Extremely low noise, ideal for laboratory applications
  • Easy integration thanks to the UL and IEC 61010 certification of the entire pump
