Liquid Ring Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is situated eccentric to the cylinder body(Vacuum pump casing). Vacuum is created in the vacuum pump by using a liquid seal. … When the impeller begins to rotate, the liquid can be starts move outward by centrifugal power.

Water band vacuum pump is a common kind of liquid band vacuum pump. Water ring is definitely a rotor with multi-blades eccentrically set up in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid band concentric with the pump shell. The liquid ring and the rotor blade form a rotating variable capacity vacuum pump with periodic quantity change. When the working liquid is water, it is called water Band vacuum pump. There are several kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type selection of water ring vacuum pump ought to be based on your on-site process, the required vacuum level and the Water Vacuum Pump amount of air pumping required.
