Liquid Band Vacuum Pump Working Theory. 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 utilizing a liquid seal. … When the impeller starts to rotate, the liquid can be starts move outward by centrifugal pressure.
Water ring vacuum pump is a common type of liquid ring vacuum pump. Water band is a rotor with multi-blades eccentrically installed in the pump shell. When it rotates, it throws liquid into the pump and forms a liquid band concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capacity vacuum pump with periodic quantity change. When the working liquid is water, it is called 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 band vacuum pump ought to be predicated on your on-site procedure, the required vacuum Water Vacuum Pump degree and the amount of air pumping required.
