Dry Vacuum Pumps - SIHI Dry Chemicals PD-Systems

SIHI Dry - PD-Systems are designed for chemical and pharmaceutical markets where an explosion proof design is required. The SIHI Dry is a vertically oriented and self-draining vacuum pump with no mechanical shaft seals. 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. Moreover, this method of rotor synchronization permits gearbox-free operation in which to run extremely quietly, and without any lubrication. Eight sizes of SIHI Dry were developed for operation with explosive media, both internally and externally, and offer volumetric flow rates up to 1000 m³/h (589 cfm). Dramatic increases to flow and pressure are available in combination with SIHI Boost.
