Liquid Band Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is situated eccentric to the cylinder body(Vacuum pump casing). Vacuum is created in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid is begins move outward by centrifugal force.
Water ring vacuum pump is a common type of liquid ring vacuum pump. Water band can be a rotor with multi-blades eccentrically installed 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 band and the rotor blade form a rotating variable capability vacuum pump with periodic 
volume change. When the functioning liquid is drinking water, it is called water Ring vacuum pump. There are numerous kinds of water band vacuum pumps with different prices. .Water Vacuum Pump Included in this, 2BV is more cost-effective. The sort selection of water band vacuum pump ought to be predicated on your on-site process, the required vacuum level and the amount of air pumping required.
