ⓘ Explanation

1 The series in the table represents the recommended standards. Due to the varying working conditions in actual production applications, the gas intake and pressure will undergo many changes. Therefore, during the selection process, calculations or reference to the usage of existing equipment should be conducted based on the actual vacuum extraction process, gas release process, condensation of non-volatile gases, time variations of the intake pressure, etc.
2 The technical indicators of the single pump are detailed in the respective pump parameter tables.
3 The maximum intake pressure refers to the highest pressure that the main pump can start at. If it operates for a long time at a pressure higher than this, it will cause the main pump to overload.
4 If the vacuum pump motor, electrical contact vacuum gauge/pressure transmitter, and electrical control cabinet need to be explosion-proof, please specify during the order. The 2BV5 water ring vacuum pump in the table should be correspondingly changed to the 2BV6 series.

❓ Frequently Asked Questions

Q What does the unit model designation (e.g., JZJ2B300-2) indicate?

A The unit model code identifies the specific configuration of the vacuum pump system, including the main pump series, draw rate capacity, and the number or type of pre-stage pumps used. Each model is matched to a recommended combination of main pump and pre-stage pump to achieve the specified absolute vacuum level and total power.

Q How should I select the right vacuum pump unit for my application?

A Selection should be based on your actual vacuum extraction process, gas release characteristics, condensation of non-volatile gases, and the time variation of intake pressure. The table provides recommended standards, but actual working conditions may vary significantly — calculations or reference to existing similar equipment is strongly advised before making a final selection.

Q What is the maximum intake pressure, and why does it matter?

A The maximum intake pressure is the highest pressure at which the main pump can be safely started. Operating the pump continuously above this pressure threshold will cause the main pump motor to overload, potentially leading to equipment damage or failure. Always ensure the system pressure is within the specified range during startup and continuous operation.

Q When should I choose the 2BV6 series instead of the 2BV5 water ring vacuum pump?

A If your application requires explosion-proof equipment — including an explosion-proof vacuum pump motor, electrical contact vacuum gauge, pressure transmitter, or electrical control cabinet — you must specify this requirement at the time of order. In such cases, all 2BV5 water ring vacuum pumps listed in the table should be replaced with the corresponding 2BV6 explosion-proof series.

Q Where can I find the detailed technical parameters for individual pumps in the system?

A The technical indicators and detailed specifications for each individual pump (such as the ZJP series main pumps and 2BV/2BE series pre-stage pumps) are provided in their respective pump parameter tables. Please refer to those dedicated parameter sheets for flow rate curves, motor ratings, flange dimensions, and other technical data.

Q Can the vacuum pump units in this table be customized for special working conditions?

A Yes. The models listed represent recommended standard configurations. For applications with special gas compositions, unusual pressure ranges, high-temperature environments, or hazardous area classifications (requiring explosion-proof components), customized configurations are available. Please consult with the manufacturer and provide detailed process parameters to ensure the most appropriate unit is specified for your requirements.
