Introduction:
JZJ2B series Roots-Liquid Ring Pump System is a vacuum pumping system containing a roots pump as its main pump, and a 2BV types of liquid ring pump or a system of roots-liquid ring pump as fore pump.

Advantage:
Comparing with common liquid ring vacuum pump,the capacity to remain high pumping speed under high or ultimate vacuum degree becomes its main advantage. Except for normal gas suction, this system can also pump special gas with small amount of vapor or dust. Additionally, this system is free from oil pollution, as well as vapor and dust.
Since the 2BV type of liquid ring pump has been adopted as its fore pump, the JZJ2B series system is more efficient than JZJ2S series (which 2SK type of liquid ring pump has been adopted). And it is compact-designed with no air leakage and high protection level. Besides,our 2BV type is more anti corrosive than 2SK type, because all 2BV impeller are SS304 material.
Another note, the fore pump can be designed as a closed circulation system so to reduce the environment pollution greatly.

Application:
JZJ2B series system has become an ideal choice for vacuum drying or dehydration process, and vacuum degassing process in the field of light textile, food industry, chemistry, pharmacy, etc.

Remark:

1. Above are recommended models as per national standards. Since the suction pressure will be changed as per distinguished working condition, before model selection, the verifying calculation as per actual suction and discharging process, condensation situation of condensable gas, changing time for suction pressure is required. Or referring to the clients current system is also workable.

2. Please refer to instructions of each pump for technical parameter checking.

3. The max suction pressure means the pressure under which the main pump can work. Over this degree, the main pump will be result to overloaded.

4. If a motor, electric joint, anti-explosive for electric cabinet is required, please clear clarify this on PO. And the 2BV2 series on above sheet will be changed to 2BV2-EX series, and 2BV5 series be 2BV6 series.
