They are widely used in paper-making, chemical, petrification, light industry, pharmacy, instruments, metallurgy, construction, electronical appliance, coal-cleaning, mineral concentration, fertilizer, etc.
2BE liquid ring vacuum pump is single stage pump with simple structure. It’s easy maintenance, reliable,efficient and energy-saving operation . They can run under tough working conditions with large drainage discharge and changing load impact. 2BE vacuum pumps adopt unique polytetrafluoroethylene valve plates (former liquid ring pumps use ball valves) for their exhausting systems. Each valve plate is covered on vents in outer side of a port plate and fixed by a stainless steel baffle at its other side. Curvature of the valve plate changes with inlet pressure so that pumping medium can be discharged when it reaches the inlet pressure. Such structure avoids over-compression in a vacuum system and automatically adjusts exhausting area to lower power consumption, thus a best operating efficiency can be obtained.
The key parts of 2BE series liquid ring vacuum pumps, such as distribution plate, impeller and pump shaft are simplified in structure with performance improved, thus it’s very energy-saving.
Dynamic balance problem is radically solved because during impeller welding, blades are formed by one-step stamping with rational molded lines and all wheel hubs are processed. The impeller and pump shaft combined by shrinkage interference fit perform reliably and smoothly. Blades of the impeller will obtain good ductility after the impeller is welded and processed by overall heat treatment, thus impact resistance and flexure resistance of the blades are fundamentally guaranteed the application under tough working condition with changing load impact.
The 2BE pumps are equiped with gas-water separators itself, Many position has the exhausting hole. It is very easy to connect with the vacuum system. What’s more, the pump cover with inspeciton window which can regulate the gland packing of the shaft to adjust the impeller and distributoring plate. All vacuum pumps will be subjected to strict inspections and tests in our testing center so as to guarantee their excellent, reliable and long lasting performances.

2BV series Liquid ring vacuum pump
2BV series Liquid ring vacuum pump Image

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). If the transformer oil is used as the operating liquid, these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i.e. 99 % vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When the liquid ring vacuum pumps work under the condition near the ultmost vacuum for a long time, it is necessary to couple with the cavitation protection pipe in order to get rid of the screaming so as to protect the pump. When the 2BV pumps are used as compressor, it should check the discharge pressure and select suitable motor power because the motor power will be increasing along with the exhausting pressure.
Main Features:
1. The direct connection of the motor and pump with the same shaft saves space and convenient installation
2. Adopting mechanical seal as standard configuration,which can eliminate leakage and make the maintenance convenient.
3. operate steadily and the noise low to 62 dB
4. All the components are processed precisely by the CNC lathe, and the mechanical seal adopts international famous brand such as John Crane or Bergman to ensure the precision.
5. Take NTN or NSK international famous brand bearing.
6. 2BV series liquid ring pump can be combined with ZJ series Roots vacuum pump to make roots and liquid ring vacuum system. The ultimate vacuum can be 5pa. The 2BV liquid ring vacuum pump also can be coupled with separator and heat exchanger to make closed circulation unit, which improved the safety and reliability by one pump working, one pump backup.
