Pfeiffer Vacuum Introduces Pascal 2021 HW Two-stage Rotary Vane Pump

Pfeiffer Vacuum’s new Pascal 2021 HW two-stage rotary vane pump, offering the highest vapor capacity in its class, is ideally suited for all applications where water vapor is expected, such as low temperature sterilization and drying.

With an optimized design and gas ballast system, the Pascal 2021 HW unit pumps large volumes of vapor without condensation inside the pump, in turn, preventing accumulation of fluid that would adversely affect the service life of the pump and the oil. Thanks to materials used, the pump also resists aggressive chemicals such as hydrogen peroxide. Additionally, it is ready to deliver vapor in just a few minutes due to a customized temperature management. The pump also has a safety device that impedes the ingress of water into functional sections if the steam capacity is inadvertently exceeded.

With accessories such as an oil mist filter and inlet traps, the pump can be adapted to most processes. With its compactness, the Pascal 2021 HW is also ideal for installation into equipment. An oil drain valve simplifies the 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 availability. Using different operating fluids allow maintenance intervals to be extended.
