High speed magnetic suspension vacuum pump operates with an impeller rotating at high speeds, drawing in moist air and compressing it rapidly. In single-stage turbine vacuum pumps, air is compressed by a single impeller and then expelled through a diffuser and volute casing. Multi-stage turbine vacuum pumps utilize multiple impellers to sequentially compress the air, achieving higher vacuum levels. Depending on the level of air intake, different degrees of vacuum can be produced.

High speed magnetic suspension vacuum pump incorporates innovative technologies such as magnetic bearings, high-speed permanent magnet motors, high-frequency vector variable frequency technology, and efficient fluid mechanics. It is an intelligent turbomachinery device that offers energy savings of 30-70% and water savings of 100% compared to conventional equipment. It is extensively used in the paper industry, particularly for energy-saving retrofits in vacuum dewatering processes.
