Liquid Band Vacuum Pump Working Basic principle. The vacuum pump consisting 
an impeller which is located 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 can be begins move outward by centrifugal drive.
Water band vacuum pump is a common type of liquid ring vacuum pump. Water ring is definitely a rotor with multi-blades Water Vacuum Pump eccentrically set up in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid ring concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capacity vacuum pump with periodic volume change. When the operating liquid is water, it is called drinking water Ring vacuum pump. There are plenty of kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water ring vacuum pump should be predicated on your on-site process, the required vacuum degree and the quantity of air pumping required.
