UnoLineTM Plus

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.
