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

The pump 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 the pumping of large volumes of vapour without condensation inside the pump. This prevents accumulation of fluid that would adversely affect the service life of pump and the pump oil. 

The Pascal 2021 HW utilises special materials to 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 system. It has a safety device that impedes the water from entering into functional sections of the pump if the steam capacity is inadvertently exceeded.

With accessories such as oil mist filter and inlet traps, the pump can be adapted to most processes. The compact design of the Pascal 2021 HW permits easier installation into OEM and custom equipment. An oil drain valve simplifies maintenance in confined spaces. The single-phase universal motor allows for operation almost everywhere in the world.

The proven service concept of the Pascal series makes maintenance predictable and ensures a constantly high uptime. The maintenance intervals can be extended by using long-life or inert operating fluids.
