Explanation
- 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.
- The technical indicators of the single pump are detailed in the respective pump parameter tables.
- 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.
- 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
Q1
What does the unit model designation (e.g., JZJ2B30-1) represent?
The unit model designation identifies the configuration of the vacuum pump unit, including the main pump type and the pre-stage pump combination. For example, JZJ2B30-1 indicates a roots-water ring vacuum unit with a ZJP30 main pump paired with a 2BV5110 pre-stage pump, achieving a draw rate of 30 L/S and an absolute vacuum of 267 Pa.
Q2
How should I select the right vacuum pump unit for my application?
Selection should be based on your specific working conditions, including the actual vacuum extraction process, gas release characteristics, condensation of non-volatile gases, and time variations of intake pressure. The table provides recommended standards, but calculations or reference to existing equipment usage are strongly advised before making a final selection.
Q3
What happens if the main pump operates above the maximum intake pressure for an extended period?
Operating the main pump continuously at a pressure higher than the specified maximum intake pressure will cause the main pump to overload. This can lead to increased mechanical wear, higher energy consumption, potential equipment damage, and reduced service life. Always ensure the system operates within the recommended pressure range.
Q4
Can the vacuum pump units be configured for explosion-proof environments?
Yes. If explosion-proof requirements apply to the vacuum pump motor, electrical contact vacuum gauge, pressure transmitter, or electrical control cabinet, this must be specified at the time of order. In such cases, the 2BV5 water ring vacuum pumps listed in the table should be replaced with the corresponding 2BV6 series explosion-proof models.
Q5
Where can I find the detailed technical specifications for individual pumps?
The detailed technical indicators for each individual pump — including performance curves, operating ranges, and mechanical specifications — are provided in the respective pump parameter tables. Please refer to those documents for in-depth technical data on the main pump and pre-stage pump models listed in this unit configuration table.
Q6
What is the difference between single-stage and multi-stage pre-stage pump configurations?
Single-stage configurations use one pre-stage pump (e.g., 2BV5110) paired with the main pump, achieving an absolute vacuum of 267 Pa. Two-stage configurations combine two pre-stage pumps to reach a deeper vacuum of 25 Pa, while three-stage configurations can achieve an absolute vacuum as low as 0.5 Pa. Multi-stage setups are used when extremely high vacuum levels are required in demanding industrial processes.
