Liquid ring vacuum pumps operate by supplying a liquid that is centrifuged on the pump walls. This results in a liquid ring that maintains the pump’s airtightness.
Liquid ring vacuum pumps have many advantages that may be useful if you work in industries such as distilleries, petroleum refineries, power plants, mines, sugar factories, etc. These vacuum pumps are not very sensitive to the passage of liquids, small solid particles or vapors. Additionally, their isothermal compression is ideal for explosive and heat-sensitive products, which ensures a high level of safety. Liquid ring vacuum pumps can also be used for vacuum filtration, moisture extraction, removal of water from pulp during paper processing, mineral recovery and ash handling.
With a maximum flow rate of 30,000 m³/h, these powerful pumps allow you to decrease and increase pressure. Nevertheless, we advise you to pay attention to the saturated vapor pressure of the liquid ring. The minimum pressure of the vacuum pump must not be lower than the saturation pressure of the liquid ring, otherwise the liquid ring may vaporize. This will compromise your vacuum pump’s airtightness.
