Two-Stage Rotary Vane Pump
Pascal 2021 HW is suited for applications where water vapor is expected such as low temperature sterilization and drying. The two-stage rotary vane pump has a gas-ballast system that allows the pumping of 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 pump oil. It utilizes special materials to resist aggressive chemicals such as hydrogen peroxide. The pump is ready to deliver vapor in just a few minutes due to a customized 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.
