Omschrijving Duo-Series Rotary Vane Pumps

Pfeiffer Vacuum rotary vane pumps have been the most popular pumps for generating low and medium vacuum for many years now. They are sturdy and have a long life, whether they are used as backing pumps to generate the backing pressure called for by turbopumps, or as a single standalone pump. Rotary vane pumps belong to the family of displacement pumps and convey a virtually steady low-pulsation suction volume flow, irrespective of the type of gas used. They work on the principle of an eccentrically supported rotor revolving in a housing, and have two or more movable vanes. Every Pfeiffer Vacuum rotary vane pump is oil-lubricated. Special vacuum oils, also known as operating fluids, are responsible for insulating and lubricating components, resulting in very low final pressures. The oil lubrication also ensures an extremely long lifetime, even in continuous operation.

 

A choice of versions provides the right variant for every application
Pfeiffer Vacuum rotary vane pumps cover an extremely wide range of pumping speeds from 1.25 to 1,600 m3/h (60 Hz to 1,920 m3/h). Two different types of pump are available to choose from: single-stage and two-stage rotary vane pumps. Two-stage pumps are ideally suited for processes in the medium vacuum range. Single-stage models are the pump of choice when the working pressure is mainly in the low vacuum range.
