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.
