China Suppliers Screw Water Ring Vacuum Pump Unit - Factory Direct Boosting Solution for Enhanced Vacuum Performance

Introducing our high-performance Screw Water Ring Vacuum Pump Unit, designed for optimal efficiency and reliability. This vacuum unit features a robust Screw pump as the main pumping mechanism, complemented by 2BV or 2BE water ring pumps functioning as pre-stage pumps. The water ring pump plays a crucial role in creating the necessary pre-vacuum for the Screw pump, which acts as a powerful booster. By adding additional stages of Screw pumps, the ultimate vacuum achievement can be enhanced by an impressive order of magnitude. As a leading manufacturer based in China, we pride ourselves on delivering top-quality vacuum solutions. Partner with us, your trusted suppliers and factory, to elevate your industrial processes with our advanced vacuum technologies

ⓘ 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 How do I select the correct JZJ2B vacuum unit model for my application?

A Selection should be based on your actual vacuum extraction process requirements, including gas intake volume, working pressure range, gas release characteristics, and condensation of non-volatile gases. It is recommended to perform detailed calculations or reference existing equipment usage rather than relying solely on the standard table values.

Q What does the "Absolute Vacuum (Pa)" column represent in the specification table?

A The absolute vacuum value (in Pascals) indicates the ultimate vacuum level that the unit can achieve under standard operating conditions. Units in the table are grouped by their achievable absolute vacuum: 267 Pa, 25 Pa, and 0.5 Pa, representing different levels of vacuum performance.

Q What happens if the main pump operates continuously above its maximum intake pressure?

A Operating the main pump continuously at a pressure higher than its maximum rated intake pressure will cause the pump motor to overload. This can lead to overheating, accelerated wear, and potential equipment failure. Always ensure the system pressure remains within the specified operating range during continuous 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. Additionally, the 2BV5 water ring vacuum pump listed in the table must be replaced with the corresponding 2BV6 explosion-proof series.

Q Where can I find detailed technical parameters for individual pumps used in these units?

A The technical indicators for each individual pump component — including the ZJP, ZJ, 2BV5, 2BV6, and 2BE1 series — are provided in their respective pump parameter tables. Please refer to the corresponding product datasheets or contact our technical team for detailed specifications.

Q What is the difference between single-stage and multi-stage pre-pump configurations in the JZJ2B series?

A Single-stage pre-pump configurations (e.g., JZJ2B30-1) use one pre-stage pump paired with the main pump, achieving an absolute vacuum of 267 Pa. Multi-stage configurations (e.g., JZJ2B70-2.1.1 with two pre-stage pumps) achieve significantly deeper vacuum levels down to 0.5 Pa, making them suitable for more demanding industrial vacuum applications.
