ⓘ Important Notes & 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 (FAQ)

Q What does the unit model designation (e.g., JZJ2B300-2) mean in the JZJ2B vacuum unit series?

A The model designation encodes key configuration information: the number following the hyphen indicates the number of pump stages and configuration type, while the number before the hyphen represents the nominal pumping speed (draw rate) in L/S. For example, JZJ2B300-2 features a ZJP300 main pump with a 2BV5161 pre-stage pump and a draw rate of 300 L/S.

Q How should I select the correct JZJ2B vacuum unit model for my application?

A Selection should be based on your actual process requirements, including the vacuum extraction process, gas release characteristics, condensation of non-volatile gases, and time-varying intake pressure. The table provides recommended standards, but calculations or reference to existing equipment usage should always be performed to match your specific working conditions.

Q What is the achievable absolute vacuum level for the JZJ2B series units?

A The JZJ2B series offers three absolute vacuum levels depending on configuration: 267 Pa for single-stage pre-pump units, 25 Pa for two-stage pre-pump units, and 0.5 Pa for three-stage pre-pump units. Higher-stage configurations achieve deeper vacuum levels suitable for more demanding industrial processes.

Q What happens if the main pump operates above its maximum intake pressure for an extended period?

A Operating the main pump continuously at a pressure higher than its rated maximum intake pressure will cause the main pump to overload. This can lead to increased energy consumption, accelerated wear, overheating, and potential mechanical failure. It is critical to ensure the system operates within the specified pressure range during sustained operation.

Q Can the JZJ2B vacuum units be configured for explosion-proof environments?

A 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 ordering. In such cases, the 2BV5 water ring vacuum pump listed in the standard configuration table should be replaced with the corresponding 2BV6 explosion-proof series.

Q What is the difference between the 2BV5 and 2BE1 pre-stage pump series used in these units?

A Both are water ring vacuum pumps used as pre-stage (backing) pumps in the JZJ2B units. The 2BV5 series is typically used for smaller to medium draw-rate configurations, while the 2BE1 series is applied in higher-capacity units requiring larger pumping volumes. For explosion-proof applications, the 2BV5 series should be replaced with the 2BV6 series as specified by the manufacturer.
