Pfeiffer Vacuum A Passion for Perfection

2.2.3.1 Single-stage rotary vane vacuum pumps

HenaLine™

HenaLine single-stage, oil-sealed rotary vane vacuum pumps generate a vacuum having volume flow rates of 25 to 1,000 m3 /h at ultimate pressures of up to 0.1 mbar. They can be universally employed in many industrial and research environments. They can either be operated as a stand-alone pump or integrated into pumping stations.

With appropriate accessories, these pumps are also suitable for use under the harshest operating conditions, i.e. at high inlet pressures as well as in cycle-mode operation. Oil mist filters, oil return systems and vacuum safety valves are all integrated as standard equipment. In addition to preventing pollution of the ambient air, they also protect the pump and the system. A gas ballast valve enables pump-down of water vapor and other process vapors.

UnoLine™ Plus

UnoLine Plus pumps can be optimally employed for industrial applications, first and foremost. These rotary vane vacuum pumps have proven track records as both stand-alone and backing pumps for Pfeiffer Vacuum Roots pumps. An ultimate pressure of approximately 6 · 10-2 mbar can be attained. These pumps are water-cooled and extremely insensitive to dust and dirt.

They are equipped with an oil regeneration system. Condensates, contaminants and dust particles can be separated from the operating medium, collected in the vapor separator and drained. The adjustable cooling water controller enables the UnoLine Plus pumps to maintain the required operating temperature. These pumps are equipped with gas ballast in order to pump down vapors.
