2BV water ring vacuum pump is a kind of water ring vacuum pump. As a new generation energy-saving product, 2BV water ring vacuum pump will completely replace SK, 2SK series water ring vacuum pump and W, WY, WL series reciprocating vacuum pump with excellent performance and many advantages.

2BV water ring vacuum pump is suitable for removing gas and water vapor. The suction pressure reaches 33 mbar absolute pressure (97% vacuum degree), When the vacuum pump works for a long time when the suction pressure is lower than 80mbar, the cavitation maintenance pipe should be connected to stop the maintenance of the pump. If equipped with an atmospheric jet pump, the suction pressure can reach 10mbar. The jet pump can be directly installed on the vacuum pump. When used as a tightening machine, the maximum pressure is 0.26mpa (absolute pressure). Uniform corrosion resistance design, bronze impeller improves the pump corrosion resistance, stainless steel material is more suitable for more demanding applications.

2、 Features and structure description of 2BV water ring vacuum pump:

1. Pump coaxial direct connection design saves space and is easy to install.

2. The mechanical seal is used as the standard configuration, which eliminates the leakage and is easy to maintain.

3. The operation is stable and the noise can be as low as 62 dB.

4. The unique flexible exhaust port design will not produce over compression, which ensures that 2BV has the best efficiency within its performance range.

5. All 2BV series water ring vacuum pumps are equipped with cavitation protection pipe interface. If the pump works under the limit pressure, opening the cavitation protection pipe interface (or connecting with the separator) can eliminate the cavitation sound and protect the pump under the maximum suction effect.

6. Our factory recasts all models of 2BV series water ring vacuum pump, and all blank parts are made of precision casting (stainless steel and common materials).

7. All parts are precision processed by CNC lathe, and the mechanical seal is imported John Crane or Dalian Bergman to ensure the accuracy.

8. All imported bearings are NTN or NSK.

9. The company decided to further improve the management and quality control ability of 2BV series products on the basis of comprehensive technical improvement. Within three years, this series of products will strive to become a famous brand product in Shanghai.

10. 2BV series water ring vacuum pump can be combined with ZJ series Roots pump to form jzj2b roots unit. The limit vacuum can be up to 5pa. It can also be combined with separator and heat exchanger to form 2BV closed cycle unit. One is open and one is standby, and the other is multi open and multi standby, which improves the safety and reliability of the system.

2bv-f series water ring vacuum pump / compressor is mainly used to remove explosive gas and work in various flammable and explosive environments. Its performance parameters are the same as those of 2bv-b and 2bv-e series.
