water ring vacuum pump

water ring vacuum pumps is a type of liquid ring vacuum pump that uses water (or another liquid) as the sealant to create a vacuum. The working principle involves a rotating impeller inside a cylindrical casing that is partially filled with water. As the impeller spins, the centrifugal force pushes the water outwards, creating a water ring that seals against the casing. This action traps and compresses air (or other gases) between the impeller blades and the water ring, eventually expelling it through the discharge port.
