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 created in the vacuum pump by using a liquid seal. … When the impeller begins to rotate, the liquid is certainly starts move outward by centrifugal power.
Water ring vacuum pump is a common type of liquid band vacuum pump. Water ring is definitely 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 form a rotating variable capacity vacuum pump with periodic quantity change. When the working liquid 
is water, it is called drinking water Band vacuum pump. There are various kinds of water ring vacuum pumps with different prices. .Water Vacuum Pump Included in this, 2BV is more cost-effective. The type selection of water ring vacuum pump ought to be based on your on-site process, the required vacuum level and the amount of air pumping required.
