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 created in the vacuum pump by using a liquid seal. … When the impeller begins to rotate, the liquid can be begins move outward by centrifugal power.

Water ring 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 throws liquid into the pump and forms a liquid band concentric with the pump shell. The liquid band and the rotor blade type a rotating variable capacity vacuum pump with periodic quantity Water Vacuum Pump change. When the functioning liquid is drinking water, it is called water Band vacuum pump. There are numerous kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The type selection of water band vacuum pump should be predicated on your on-site process, the required vacuum level and the quantity of air pumping required.
