Liquid Band Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is situated eccentric to the cylinder body(Vacuum pump casing). Vacuum is created in the vacuum pump by using a liquid seal. … When the impeller begins to rotate, the liquid is definitely begins move outward by centrifugal power.
Water band vacuum pump is a common kind 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 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 quantity change. When the working liquid is water, it is called water Band vacuum pump. There are several kinds of water band vacuum pumps with different Water Vacuum Pump prices. .Among them, 2BV is more cost-effective. The sort selection of water band vacuum pump ought to be predicated on your on-site procedure, the required vacuum level and the amount of air pumping required.
