Liquid ring vacuum pump animation. As the shaft turns a liquid ring is created by the centrifugal force generated by the rotating impeller. This force holds the liquid ring against the. Liquid ring vacuum pumps are rotating positive displacement machines providing process vacuum in industrial applications such as chemical electrical power environmental food beverage processing and packaging marine mining oil gas pharmaceutical pulp paper and textiles. It is due to the vacuum pump operate at the vapor pressure region of seal liquid.

To produce vacuum in a two stage liquid ring vacuum pump a multi blade impeller on a shaft is positioned eccentrically in a cylindrical housing that is partially filled with sealing liquid. If the vacuum pump run at the vapor pressure region bubbles will form in the seal liquid. Similar to other pumps a liquid ring vacuum pump lrvp has a bladed impeller attached to a center hub. In liquid ring vacuum pump the cavitation is occurs as a result of vaporization of the seal liquid.

As the bubble move from low pressure region to high pressure region the. Through our ongoing commitment to innovation product research and development nash continues to.
