JZJQ2B2500-2.2.1 Series Roots Water Ring Vacuum Unit

　　Summary:

　　JZJ2B Roots series water ring unit is consists of ZJ type roots pump as the main pump,2BV/2BE1 series of water ring pump or Roots--water ring unit as a fore pump pumping unit. It can be used to pumping gas in addition to, can also aspirate containing water, compared to organic solvent or a small amount of dust gas. And general mechanical vacuum pump, not afraid of oil pollution, not afraid of water, gas and dust, and compared with the general water ring vacuum pump, with vacuum high and pump speed characteristics under high vacuum condition.

　　Due to the adoption of the high efficiency and energy saving of 2BV series water ring pump before the class, so JZJ2B series vacuum unit than jzj2s series with high efficiency, compact structure, no leakage (2BV pump mechanical seal design, different to 2SK series packing seal) resistance to corrosion (2BV adopts stainless steel or aluminum bronze impeller）protection grade higher merit.

　　Roots vacuum pump using the company's own R & D ZJ Roots series vacuum pump，our company will pump cavity and the bearing cavity sealing was improved after the ZJ Roots series vacuum pump in the pumping process of a large number of water vapor and various solvents oil pump is not easy to be emulsified.

　　Roots water ring vacuum unit of pump working fluid with water, can also be used in organic solvents (methanol, alcohol, xylene, acetone and other organic solvent ) or other liquid, using pre - pump as a closed circulation system，can greatly reduce the pollution to the environment, and greatly improve the recovery of the organic solvent. The limit vacuum degree by the working fluid saturated vapor pressure.
