Water Vacuum Pump liquid Ring 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 utilizing a liquid seal. … When the impeller begins to rotate, the liquid is usually begins move outward by centrifugal force.
Water ring vacuum pump is a common kind of liquid band vacuum pump. Water band is definitely a rotor with multi-blades eccentrically set up 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 type a rotating variable capacity vacuum pump with periodic quantity change. When the operating liquid is drinking water, it is called water Band vacuum pump. There are several kinds of water band 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 procedure, the required vacuum level and the amount of air pumping required.
