Single Stage Liquid Ring Vacuum Pump (SK)
Water Ring Single Stage Vacuum Pump (commonly referred to as a water ring pump) is a type of rough vacuum pump that can achieve an ultimate pressure of 4–8 kPa for single-stage models and 2–4 kPa for two-stage models. These pumps are widely used in various technical processes across industries such as petroleum, chemical, machinery, mining, light industry, papermaking, power, metallurgy, medicine, food, and more, as well as in municipal and agricultural sectors. Common applications include vacuum filtration, feeding, degassing, evaporation, concentration, and regeneration.
Due to the isothermal compression process, water ring pumps are capable of handling flammable and explosive gases, as well as gases containing dust or moisture, making them increasingly popular in industrial settings.
**Applications**
These pumps are primarily designed to handle air and other non-water-soluble gases with some degree of corrosiveness and minimal dust content. They are extensively used in vacuum evaporation, concentration, feeding, dehydration, and drying processes within fields such as food processing, textiles, pharmaceuticals, and chemicals. The series features compact designs, high reliability, easy installation, disassembly, and maintenance.
