Dry Vacuum Pumps - SIHI Boost Chemical PB-Systems


SIHI Boost - PB-Systems are designed for chemical and pharmaceutical markets where an explosion proof design is required. SIHI Boost is a dry screw vacuum booster, which provides  deep vacuum levels with less power and a smaller footprint. The rotors run five times faster than typical machinery, it is quieter, safer and cleaner. Mechatronically synchronized, contact-free moving parts reduce the need for oil-centric lubrication. In opposite to typically used Roots type booster pumps, SIHI Boost is designed for high discharge pressure which allows direct combination with Liquid Ring Backing pumps, the most robust vacuum pump for harsh process conditions. It is an ideal choice for chemically related processes where there is a high possibility of liquids or solids carry-over. This award winning solution can accommodate corrosive gases and vapors and has superior resistance to heat-accelerated deposition. The basic layout provides the platform for an extensive range of intelligent modules which can be incorporated in order to match dynamic process requirements, simple DCS integration, and remote monitoring. Integrated within the pump is the intelligent drive system that performs ongoing rotor diagnostics, while giving an energy efficient platform for variable speed/pressure control.
