Doctor - Model 2BV5 131 -Single Stage Liquid Ring Vacuum Pump

This pump works basing on water ring principle, that is, impeller is installed eccentrically inside of pump body, after the pump start up, working liquid forms liquid ring(which is concentric with pump body ) inside of pump body, impeller passes motor power to liquid ring. Liquid ring pulse periodically between the impeller vanes, while in pulsation, gas is suctioned in through disk suction inlet and discharged from disk exhaust vent.

• Pump casing material:cast iron
• Impeller material:stainless steel 304
• Seal:Viton mechanical seal
• Teflon coating disposal inside pump casing and pump cover

It is widely used in all kinds of plastic extrusion line,medical and pharmaceutical industry(autoclave,sterilizer,capsule filling machine),EPS foam machine,food-related industry,chemical industry(vacuum filtration,vacuum water diversion,vacuum feeding,vacuum evaporation,vacuum concentration,vacuum reflow,vacuum degassing)
