2BV series water ring vacuum pumps and compressors

  Download the brochure of 2BV series (pdf)

  Summary:

  2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 % vacuum degree). When the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect the pump. If used as a compressor, its pressure is up to 0.26MPa (absolute pressure). 2BV series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.


  2BV2-Ex, 2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series products.

  2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or the lustration.
  According to the working situation, the material of all the parts where the liquid flows (i.e. pump casing, pump cover, port plate and impeller) are made of various stainless steel as bellow:The impeller,disc,Pump cover,Pump bodyMaterial can be used
  SUS304(0Cr18Ni9)
  SUS316(0Cr17Ni12Mo2)
  SUS316L(00Cr17Ni14Mo2)
    The material of the shaft is 2Cr13 or 0Cr18Ni12Mo2Ti
  The mechanical seals are used the John Crane products and the seals material is optional for FPM or PTFE.

 

  Main features:

  • .The close-coupled design is convenient to install and can save space.
  • .The standard seals are all used the John Crane mechanical seals.
  • .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.
  • .Aluminium 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 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.
  • .The bearings are all used the imported products with brand name of NTN or NSK.
  • .2BV series water ring vacuum pump can achieve flexible sealing parts all of PTFE, which can greatly extend the life of the vacuum pump in harsh conditions

  Notes:

  1. The curve is obtained under the situation that the suction medium is saturation air at 20oC, the operating liquid at 15oC, and the discharge pressure is 1013mbar. The performance tolerance is 10%. 
  2. The flowrate data of the operating liquid indicates the data when the pump connects with the separator that only parts of the liquid are consumed. If the operating liquid doesn’t circulate, the consumed volume is 2 times as the data in the diagram.
 Note: The curve is obtained under the situation that the suction medium is saturation air at 20oC, the operating liquid at 15oC, and the discharge pressure is 1013mbar. The performance tolerance is 10%. The right curves in the diagram indicates the data when the pump connects with an ejector. 
 

 For example:

 ①Design point parameter:
  Suction capacity v=200m3/h
  Suction pressure P1=200mbar

 ②The others parameter is the same as the standard situation. (See Notes)
  Select the nearest curve to the design point1.

 ③ For instance: 111V
 Check the corresponding type according the curve No.
  (Namely the order no.,but only limit to the standard type)
  The pump type is
  2BV5111 (non-explosive) and 2BV6111 (explosive-proof) through checking "111" in the curve.

 ④Water ring vacuum pump water temperature has great influence on its performance and water ring vacuum pump performance curve were measured in 15 ℃ temperature conditions, so in the practical use of water ring vacuum pump coping water ring vacuum pump of the pumping speed is corrected. Correction method please refer to: water temperature of water ring vacuum pump performance.
