Liquid Ring Vacuum Pump Working Theory. 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 starts to rotate, the liquid is certainly begins move outward by centrifugal power.
Water band vacuum pump is a common type of liquid ring vacuum pump. Water band can be a rotor with multi-blades eccentrically set up in the pump shell. When it rotates, it Water Vacuum Pump throws liquid into 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 functioning liquid is water, it is called drinking water Ring vacuum pump. There are various kinds of water band vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of 
water ring vacuum pump should be based on your on-site process, the required vacuum degree and the amount of air pumping required.
