Sterling SIHI pumps


Sterling SIHI

Delivery program Vacuum pumps

Vacuum technology worldwide

Sterling SIHI - liquid ring vacuum pumps are in usage in their basic function since 1925. The constant exchange of experience with our customers and the continuous development have shaped Sterling SIHI pumps. We are continuously researching with the aim of developing innovations for the future.

In addition to the liquid-ring vacuum pumps liquid ring compressors, gas radiators and dry running vacuum pumps provide an economical and environmentally friendly production of gases.

There are liquid ring vacuum pumps in single-stage and double-stage design with a pumping speed up to 12.000 m3/h. They are used in a range of pressure from 33 up to 1013 mbar, the so-called low vacuum. These pumps can be used as compressor above the atmospheric pressure.

The high reliability even under the toughest conditions is due to the robust construction. Their insensitivity to dirt in the pumped liquid makes them indispensable for the practice.

Our pump range is based on a comprehensive modular system. Many variation possibilities make it possible to realize application-oriented versions of material in a process-optimized way. You can choose between grey iron, spheroidal iron, cast-bronze and stainless steel or titanium.

Where ever you look for competent problem solutions in the transport of gases and vapours, we are the competent partner.
