Liquid Band Vacuum Pump Working Principle. The vacuum pump consisting an impeller which is situated eccentric to the cylinder body(Vacuum pump housing). Vacuum is established in the vacuum pump by using a liquid seal. … When the impeller Water Vacuum Pump starts to rotate, the liquid is starts move outward by centrifugal power.

Water ring vacuum pump is a common type of liquid ring vacuum pump. Water ring is certainly 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 ring concentric with the pump shell. The liquid band and the rotor blade form a rotating variable capacity vacuum pump with periodic quantity change. When the operating liquid is water, it is called drinking water Band vacuum pump. There are plenty of 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 should be predicated on your on-site procedure, the required vacuum degree and the quantity of air pumping required.
