The SIHIdry meets the need for a robust, intelligent and reliable vacuum pump offering outstanding liquid and particle carry-over capabilities while precisely matching duty conditions with a totally controled temperature profile:

- Two vertical non-contacting screws rotate in opposite directions, transporting the gas from the top inlet to the bottom outlet of the casing.
- The shaft are supported by bearings which are at atmospheric pressure and not exposed to vacuum.
- The two electronically synchronised motors are located within the pump ensuring that no mechanical shaft seals or gears are needed.

The benefits of this design include:
- capable of handling particle and liquid carry-over, - no consumption and no disposal of operating fluid or lubricant, - up to 20,000 hours running time between maintenance checks, - minimum maintenance required, - fail safe operation under adverse process conditions, - low operating costs, - no need for flame arresters for Zone 1 and Zone 2 applications
