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

Water ring vacuum pump is a common type of liquid ring vacuum pump. Water band is usually 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 ring concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capability vacuum pump with periodic quantity change. When the functioning liquid is water, it is called water Band vacuum pump. There are numerous 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 should be based on your on-site procedure, the required vacuum level and the amount of air pumping required.
