Liquid Ring Vacuum Pump Working Theory. The vacuum pump consisting an impeller which is located eccentric to the cylinder body(Vacuum pump housing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller starts to rotate, the liquid is usually begins move outward by Water Vacuum Pump centrifugal push.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water ring is certainly a rotor with multi-blades eccentrically set up in the pump shell. When it rotates, it throws liquid in to the pump and forms a liquid ring concentric with the pump shell. The liquid band and the rotor blade type a rotating variable capacity vacuum pump with periodic quantity change. When the functioning liquid is water, it is called water Ring vacuum pump. There 
are numerous kinds of water band vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type selection of water band vacuum pump should be predicated on your on-site process, the required vacuum degree and the quantity of air pumping required.
