2BV series stainless steel explosion proof water ring vacuum pump for industry


2BV series vacuum 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.


  • The close-coupled design is convenient to install and can save space.
  • The bearings are all used the imported products with brand name of NTN or NSK
  • The standard seals are all used the John Crane mechanical seals, eliminating leakage, easy maintenance
  • 2BV series products have the cavitation protection port. When they work under the condition near the limited vacuum, the cavitation protect port opens (or connects with the separator)to get rid of the screaming to protect the pump.
  • Aluminum bronze impeller is of high intensity and wearing well. The erosive-proof capacity of the pump can be improved by using it. If the parts where the liquid flows are made of the stainless steel,the pumps can be used under the more rigorous condition.
  • The unique design of the discharge port can protect the pump from the over-pressure to ensure the best efficient performance in the working range of the 2BV vacuum pump.
  • The motors are all adopted Y2 series products. The protection class is IP54 or IP55 (normal is IP44) and the insulation grade is F.(normal is B).
  • 2BVwater ring vacuum pump can achieve all of the PTFE flexible seal, which can greatly extend the working life in more demanding conditions
  • Running smoothly, the noise can be as low as 62 db.
