Rotary vane pump
The new Pascal 2021 HW from Pfeiffer Vacuum, Nashua, N.H., boasts a 2-stage rotary vane pump with what is said to be the highest vapor capacity on the market.
Optimally suited for all applications where water vapor is expected, such as low temperature sterilization and drying, the optimized design and gas ballast system 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 pump and the pump oil.
The Pascal 2021 HW utilizes special materials to resist aggressive chemicals such as hydrogen peroxide. Plus, the pump is ready to deliver vapor in just a few minutes due to a customized temperature management system. The safety device impedes water from entering into functional sections of the pump if the steam capacity is inadvertently exceeded.
Additional accessories such as oil mist filter and inlet traps make it so it’s adaptable to most processes.
