SK-0.15 Direct Water Ring Vacuum Pump


The SK series water ring vacuum pumps and compressors are designed for pumping or compressing air and other non-corrosive, non-water-soluble, and particle-free gases to create vacuum or pressure within a closed system. These pumps are widely used in industries such as machinery, petrochemicals, pharmaceuticals, food processing, sugar production, and electronics. Due to the isothermal compression process during operation, they are safer when handling explosive gases, making them more versatile in various applications.

Note: The performance values listed are based on standard conditions: 1) water temperature at 15°C; 2) ambient air temperature at 20°C; 3) relative humidity of 70%.

As shown in the diagram, the impeller is installed eccentrically inside the pump casing. When the pump starts, a certain amount of water is injected into the pump. As the impeller rotates, the water is thrown outward by centrifugal force, forming a rotating water ring along the inner wall of the casing. During the first half of the rotation, the space between the impeller blades expands, creating a low-pressure area that draws in gas from the inlet. In the second half of the rotation, this space decreases, and the compressed gas is discharged when the pressure exceeds atmospheric pressure. This cycle continues, allowing the pump to continuously draw in and expel gas.

During prolonged operation, the water inside the pump heats up, and some of it is expelled along with the gas. To maintain efficiency and prevent overheating, a continuous supply of cold water is necessary to cool and replenish the water used in the process.
