Liquid ring vacuum pump, with a maximum vacuum of 33 hPa, gas volume ranging from 240 to 26,000 cubic meters per hour, packing or mechanical seal. It can suck flammable and explosive gases. Widely used in industries such as papermaking, chemical engineering, petrochemicals, light industry, pharmaceuticals, food, metallurgy, building materials, mine washing, mineral processing, and fertilizers.

Small liquid ring vacuum pump, with coaxial design of the motor and pump, mechanical seal, compact in size, with a maximum vacuum of 33 hPa, and a gas volume range of 27 to 500 m3/h. Typical applications: vacuum filtration, vacuum distillation, vacuum packaging, food drying, vacuum water extraction, medical suction, etc.

Large liquid ring vacuum pump, with a gas volume of 4200 to 62400 m3/h, a maximum vacuum of 160 hPa, top exhaust or side exhaust. Widely used in industries such as chemical engineering, papermaking, coal washing, mineral processing, petrochemicals, light industry, metallurgy, building materials, stone machinery, fertilizer, etc. for large air extraction rate conditions.

This two-stage liquid ring vacuum pump has an air volume range of 145 to 2500 m³/h. It can achieve a larger suction volume within a higher vacuum range. It is particularly suitable for vacuum drying, evaporation, distillation, concentration, filtration, dehydration, and degassing processes.

The application of water ring pumps in the chemical industry over the years has enabled us to accumulate rich experience in the use of special materials. This includes the application of stainless steel for flow components, the successful use of special parts coated with Ni, Cr, polymer spraying, and all titanium materials. Under conditions where the circulating medium contains strong acids, strong bases, flammable and explosive substances, toxic and harmful substances, our products can ensure smoother operation, more reliable performance, and longer lifespan.

The SZ series water ring vacuum pumps and compressors are modified versions of products imported from the former Soviet Union in the 1960s and 1970s. Previously, they were mainly used in vacuum water intake projects for large water pumps.

Two-stage liquid ring vacuum pump, compact structure and convenient maintenance; It is widely applied in the fields of machinery, petrochemicals, pharmaceuticals, food, sugar industry and electronics.
