SIHI Dry Vacuum Pumps

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, whilst maintaining a simple, cost-effective solution.

Technical Data

• Suction volume flow: up to 1,000 m³/h
• Suction pressure: < 0.001 up to 1013 mbar
• Product Series Chemical Execution: M / H
• Product Series Industrial Execution: V / S

Design

SIHIdry 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.
