Roots-Liquid Ring Vacuum system is composed of Roots Vacuum Pump as the main pump, 2BV Water Ring Vacuum Pump or Roots-Liquid Ring Vacuum system as the front pump. It not only can be used to remove ordinary gases, but also can suck gas containing water and a small amount of dust. Compared with the general mechanical vacuum pump, it has the advantages of no fear of oil pollution, no fear of water gas and dust, and compared with the general liquid ring vacuum pump, it has the advantages of high limit vacuum and pumping speed in higher vacuum conditions.
Roots Liquid Ring Vacuum system features:
1. Roots Vacuum system adopts 2BV type liquid ring vacuum pump with high efficiency and energy saving as the front pump, so Roots liquid ring vacuum system has high efficiency, compact structure, no leakage (2BV series is mechanical seal standard design, different from 2SK type Liquid Ring Vacuum pump packing seal), corrosion resistance (2BV series uses aluminum bronze impeller). The advantages of high protection level.
2. The working fluid of the front-stage pump of Roots Liquid Ring Vacuum system is mostly water. Organic solvents (methanol, ethanol, xylene, acetone and other organic solvents) or other liquids can be used. The use of the front-stage pump as a closed-circuit circulating system greatly reduces the pollution to the environment and greatly improves the recovery of organic solvents. The ultimate vacuum degree is determined by the saturated vapor pressure of the working fluid.

Roots Liquid Ring Vacuum system notes:
1. Understand the composition of the gas being pumped, whether there is condensable vapor in the gas, whether there is particulate dust, whether there is corrosiveness and so on. When selecting a vacuum pump, it is necessary to know the composition of the gas and select the corresponding pump for the selected gas. If the gas contains steam, particles, and corrosive gases, it should be considered to install auxiliary equipment in the pump inlet pipeline, such as condensers, dust collectors, etc.
2. The working pressure of Roots vacuum system should meet the limit vacuum and working pressure requirements of vacuum equipment.
3. Correctly select the working point of Roots vacuum system. The normal working range of Roots vacuum unit is the maximum suction pressure to the limit pressure of 5.
4. Under its working pressure, the vacuum system should be able to discharge all the gas produced in the process of vacuum equipment.
5, choose suitable unit configuration according to actual working conditions.
