Liquid Ring Water Vacuum Pump vacuum Pump Working Principle. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump casing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is certainly starts move outward by centrifugal pressure.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water band can be a rotor with multi-blades eccentrically installed in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid ring concentric with the pump shell. The liquid band and the rotor blade form a rotating variable capacity vacuum pump with periodic 
volume change. When the operating liquid is water, it is called water Ring vacuum pump. There are various kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water ring vacuum pump ought to be based on your on-site procedure, the required vacuum degree and the quantity of air pumping required.
