Liquid Ring Vacuum Pump Working Principle. The vacuum pump consisting an impeller which is situated eccentric to the Water Vacuum Pump 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 can be starts move outward by centrifugal push.
Water band vacuum pump is a common kind of liquid band vacuum pump. Water ring can be 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 volume change. When the operating liquid is drinking water, it is called water Ring vacuum pump. There are numerous kinds of water band vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The sort selection of water ring vacuum pump ought to be predicated on your on-site process, the required 
vacuum level and the amount of air pumping required.
