Liquid Band Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is located 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 can be begins move outward by centrifugal power.
Water ring vacuum pump is a common type of liquid ring vacuum pump. Water ring is definitely 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 band and the rotor blade type a rotating variable capacity vacuum pump with periodic quantity change. When the working liquid is drinking water, it is called drinking water Band vacuum pump. There are plenty of kinds of water band vacuum pumps with Water Vacuum Pump different prices. .Included in this, 2BV is more cost-effective. The sort selection of water ring vacuum pump ought to be predicated on your on-site procedure, the required vacuum degree and the quantity of air pumping required.
