Liquid Ring Vacuum Pump Working Basic principle. The vacuum pump Water Vacuum Pump consisting an impeller which is located 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 band vacuum pump is a common kind of liquid ring vacuum pump. Water ring can be 
a rotor with multi-blades eccentrically installed in the pump shell. When it rotates, it throws liquid in to the pump and forms a liquid band concentric with the pump shell. The liquid ring and the rotor blade form a rotating variable capability vacuum pump with periodic quantity change. When the operating liquid is drinking water, it is called water Ring vacuum pump. There are many 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 based on your on-site process, the required vacuum level and the amount of air pumping required.
