Liquid Ring 
Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is situated eccentric to the cylinder body(Vacuum pump housing). Vacuum is established in the vacuum pump by utilizing a liquid seal. … When the impeller starts to rotate, the liquid is certainly begins move outward by centrifugal drive.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water ring is usually 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 type a rotating variable capacity vacuum pump with periodic quantity change. When the functioning liquid is drinking water, it is called water Band vacuum pump. There are numerous kinds of water band vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water ring vacuum pump should be Water Vacuum Pump predicated on your on-site procedure, the required vacuum degree and the amount of air pumping required.
