Water Vacuum Pump liquid Ring Vacuum Pump Working 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 using a liquid seal. … When the impeller starts to rotate, the liquid is begins move outward by centrifugal pressure.

Water ring vacuum pump is a common type of liquid band vacuum pump. Water ring is usually a rotor with multi-blades eccentrically installed 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 working liquid is drinking water, it is called water Band vacuum pump. There are numerous kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water ring vacuum pump ought to be based on your on-site procedure, the required vacuum level and the quantity of air pumping required.
