Water Vacuum Pump 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 using a liquid seal. … When the impeller starts to rotate, the liquid can be starts move outward by centrifugal pressure.
Water band vacuum pump is a common type of liquid ring vacuum pump. Water ring can be 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 band concentric with the pump shell. The liquid ring and the rotor blade form a rotating variable capability vacuum pump with periodic volume change. When the working liquid is drinking water, it is called drinking water Ring vacuum pump. There are several kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The sort selection of water band vacuum pump should be predicated on your on-site process, the required vacuum level and the amount of air pumping required.
