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 established in the vacuum pump by utilizing a liquid seal. … When the impeller begins to rotate, the liquid can be begins move outward by centrifugal pressure.

Water band vacuum pump is a common kind of liquid band vacuum pump. Water ring is 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 ring concentric with the pump shell. The liquid band and the rotor blade form a rotating variable capability vacuum pump with periodic quantity change. When the working liquid is water, it is called water Band vacuum pump. There are plenty of kinds of water band vacuum pumps with different prices. .Among them, 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 amount of air pumping required.
