Liquid Band Water Vacuum Pump Vacuum Pump Working Theory. 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 using a liquid seal. … When the impeller begins to rotate, the liquid is certainly starts move outward by centrifugal pressure.

Water ring vacuum pump is a common kind of liquid ring vacuum pump. Water band is definitely 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 type a rotating variable capability vacuum pump with periodic volume change. When the working liquid is water, it is called water Ring vacuum pump. There are plenty of kinds of water ring vacuum pumps with different prices. .Among them, 2BV is more cost-effective. The type selection of water band vacuum pump ought to be based on your on-site process, the required vacuum degree and the quantity of air pumping required.
