SIHI Boost Screw Booster Chemical PB A Vacuum Pumps have been developed for the requirements of booster pumps in fine vacuum pressure range in hazardous areas. Offering high compression ratio allows significantly lower backing pump capacity. Deep process pressures can be realised with almost every backing pump technology, like liquid ring, screws and claw vacuum pumps. This pump offers the following unique features: - Handling of gases and condensable vapours - Optimized for process applications - Capable of handling solid carry over - Entirely oil free operation - Simple to maintain - Highly reliable - Low noise and vibration - Condition monitoring options adaptable. Applications: - Processing of gases and condensable vapours, capable of handling particles.
