Liquid Ring Vacuum Pump Working Basic principle. The vacuum pump consisting an impeller which is situated Water Vacuum Pump 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 is definitely begins move outward by centrifugal force.
Water band vacuum pump is a common type of liquid band vacuum pump. Water band is certainly 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 band concentric with the pump shell. The liquid ring and the rotor blade form a rotating variable capability vacuum pump with periodic quantity change. 
When the working liquid is drinking water, it is called drinking water Ring vacuum pump. There are numerous kinds of water band vacuum pumps with different prices. .Included in this, 2BV is more cost-effective. The sort selection of water ring vacuum pump ought to be based on your on-site procedure, the required vacuum level and the amount of air pumping required.
