Pfeiffer Vacuum presents new two-stage rotary vane pump

German manufacturer, Pfeiffer Vacuum, presents the new Pascal 2021 HW – a two-stage rotary vane pump with the highest vapour capacity in its class.

The Pascal 2021 HW is optimally suited for all applications where water vapour is expected, such as low temperature sterilisation and drying. An optimised design and gas ballast system allows large volumes of vapour to be pumped without condensation inside the pump. This prevents accumulation of fluid that would adversely affect the service life of the pump and the oil. 

Thanks to the materials used, the Pascal 2021 HW also resists aggressive chemicals such as hydrogen peroxide. The pump is ready to deliver vapour in just a few minutes due to a customised temperature management and It has a safety device that impedes the ingress of water into functional sections if the steam capacity is inadvertently exceeded.
