Two-Stage Rotary Vane Pump Pascal 2021 HW

Pfeiffer Vacuum introduced its Pascal 2021 HW two-stage rotary vane pump featuring an optimized design and gas ballast system that can pump large volumes of vapor without condensation inside the pump.

This prevents accumulation of fluid that would adversely affect the service life of the pump and the oil. It is ideal for applications where water vapor is expected, such as low temperature sterilization and drying.

The compact Pascal 2021 HW two-stage rotary vane pump resists aggressive chemicals such as hydrogen peroxide. Customized temperature management enables the pump to deliver vapor in just a few minutes.

It has a safety device that impedes the ingress of water into functional sections if the steam capacity is inadvertently exceeded. Accessories include an oil mist filter and inlet traps.
