SIHIdry H-Version (SIHI Dry H Series Dry Vacuum Pump – Industrial PD Systems)

The vacuum system SIHIdry H-version is based upon the dry running twin screw principle. The screw-shaped displacing bodies counter-rotate without contact. The pump inlet is at the top and the outlet at the geodetically lowest position (top-down pumping). In contrast to conventional pumps the both screw spindles are not mechanically but electronically synchronized. This innovative drive conception is the basis for a stepwise development of the vacuum pump to an intelligent vacuum system, which takes on additional functions as the valve-, and pressure control for example. Furthermore the intelligent system offers the possibility to exactly monitor the important process data in order to ensure a maximum of process safety.

To meet the demands of the process industry, Sterling 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 minimise life-cycle costs. The SIHIdry 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, whilst maintaining a simple, cost-effective solution.
