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 established in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is certainly begins move outward by centrifugal push.
Water band 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 band concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capacity vacuum pump with periodic volume change. When the functioning liquid is drinking water, it is called water Band vacuum pump. There are plenty of kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The sort selection of water band vacuum pump 
ought to be based on your on-site procedure, the required vacuum degree and the amount of air pumping required.
