SIHI Dry® Dry Vacuum Pumps

To meet the demands of the process industry, Flowserve-SIHI offers completely dry running vacuum pumps. Dry running vacuum pumps are used increasingly throughout industry where there is a growing demand for uncontaminated vacuum, free from oil or service liquid, a requirement for low operating pressures, a flexibility required from batch processes, concern about storage and disposal costs of service liquids and the pressure to minimize life-cycle costs. The SIHI Dry vacuum pump is a vertical twin-screw machine that is completely dry running and has no mechanical shaft seals. Moreover, the hermetically sealed unit has been developed specifically to meet these demands, while maintaining a simple, cost-effective solution.

SIHI Dry® Chemicals PD 

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.

SIHI Dry® Industrial CD

CD-Systems are designed for a broad range of industrial applications where an encapsulated, integrated pumps system design is required. Vertically oriented, and self-draining, makes the SIHI Dry ideal for industrial process where there is a high possibility of solids being carried over into the pump. Stand alone capacity ranges from 100 up to 1500 m³/h (60 up to 900 cfm), and can be increased dramatically by combining with SIHI  Boost. 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. Continual torque monitoring is another feature of the SIHI Dry design, whereby speed can be automatically adjusted in which to accommodate solids carry-over.
