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 utilizing a liquid seal. … When the impeller starts to rotate, the liquid is begins move Water Vacuum Pump outward by centrifugal power.

Water ring vacuum pump is a common kind of liquid band vacuum pump. Water ring is usually 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 band concentric with the pump shell. The liquid ring and the rotor blade type a rotating variable capacity vacuum pump with periodic quantity change. When the functioning liquid is water, it is called drinking water Band vacuum pump. There are various kinds of water ring vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water band vacuum pump should be water vacuum pump201909161443191767050based on your on-site process, the required vacuum level and the amount of air pumping required.
