Pfeiffer Vacuum DUO 11 M Rotary Vane Pump, Magnetically Coupled
This Pfeiffer Vacuum DUO 11 M rotary vane pump is new and comes complete.
The two-stage rotary vane vacuum pumps of the Pfeiffer Vacuum DUO series are designed and manufactured to meet the demanding requirements of a wide range of industrial and scientific applications. They are available in standard, magnetically coupled, and corrosion-resistant versions. Unlike the standard pump, the magnetically coupled pumps feature a frictionless magnetic coupling, eliminating oil leaks caused by a wear-prone conventional shaft seal. Thanks to their simple and highly reliable design, the two-stage rotary vane vacuum pumps of the Pfeiffer DUO series offer high performance with high pump stability, are compact, and achieve a maximum vacuum pressure of up to 10⁻³ Torr.
Magnetically Coupled Series – Unlike the standard pump, these products feature a frictionless magnetic coupling. Oil leakage through a conventional shaft seal, which is prone to wear, is impossible with these models.
