Rotary Vane Pumps

Oil Leaks are Now a Thing of the Past!

DuoLine rotary vane pumps cover all applications in the low and medium vacuum range of up to 10-3 mbar. These pumps offer reliable operation even for such critical industrial applications as drying processes, metallurgical processes or resin potting and casting systems – either as a standalone pump or as a backing pump in our CombiLine or turbopumping stations.

Thanks to their innovative drive concept, these pumps are hermetically sealed, making them clean and environmentally compatible. Because our magnetically coupled rotary vane pumps do not have radial shaft seals, there is no oil leak.

The use of a magnetic coupling minimizes maintenance requirements and leads to considerable cost savings per pump and maintenance interval.
A Complete Line of Single-Stage Rotary Vane Pumps for Low and Medium Vacuum Applications.

We now offer you a complete new line of new single-stage rotary vane pumps for all low and medium vacuum applications. These pumps offer pumping speeds of between 25 and 1,000 m3/h. Oil mist separator, oil return and safety valves are integrated as standard equipment in this line of pumps.

Their reliability, performance and compact size round out the outstanding features of the HenaLine pumps. Moreover, the principle of operation of the HenaLine pumps assures low operating temperatures.

The HenaLine innovation – Safe. Reliable. Powerful.
A New Generation of Two-Stage Rotary Vane Pumps!

Pfeiffer Vacuum is committed to innovation. It was in this spirit that we developed the new PentaLine rotary vane pumps for your applications in the low- and medium-vacuum range of down to 10-3 mbar.

The optimized drive system that is used in these pumps affords you cost-effectiveness that is convincing and environmentally friendly. The approximate 50 % reduction in power consumption compared to ordinary rotary vane pumps makes for significantly lower operating costs.

Space-saving and hermetically sealed – the innovative PentaLine is super clean and requires only little maintenance. Both man and machine benefit equally from these New Generation rotary vane pumps. As a further innovation, they incorporate a motor concept that makes them easy to deploy anywhere in the world. The PentaLine pumps run extremely quiet and with a minimum of vibration.
A Rugged Rotary Vane Pump. For Harshest Industrial Use.

The UnoLine Plus is an optimum solution for industrial applications. This rotary vane pump has a proven track record as both a stand-alone pump and as a backing pump for Pfeiffer Vacuum Roots pumps.

This is a water-cooled pump that is extremely resistant to dust and dirt. It is equipped with an oil regeneration system. This enables condensate, dirt and dust particles to be removed from the operating fluid, collected in the vapour separator and then drained. The adjustable cooling water regulating valve keeps the UnoLine Plus at the required operating temperature. The pumps are equipped with a gas ballast system for pumping off vapours.

The Workhorse for Industrial Vacuum Applications.
