📋 Notes
- The performance parameters listed in the table were obtained under the conditions of saturated air as the intake medium at 20℃, working fluid temperature at 15℃, and exhaust pressure at 1013 mbar.
- The performance tolerance is ±10%.
- The selected motor power can operate under most working conditions. If the exhaust port pressure is high (0.02 – 0.05 MPa), the motor power should be increased accordingly; if the shaft power of the 2BE1 vacuum pump is relatively low when operating normally, a motor power closer to the shaft power can be selected, which is more energy-efficient.
❓ Frequently Asked Questions
Q What is the limit vacuum level achievable by the 2BE1 series liquid ring vacuum pump?
A All models in the 2BE1 series can achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for demanding industrial vacuum applications.
Q Under what conditions were the performance parameters in the table measured?
A The listed parameters were measured using saturated air as the intake medium at 20℃, with a working fluid temperature of 15℃ and an exhaust pressure of 1013 mbar. A performance tolerance of ±10% applies.
Q What transmission methods are available for the 2BE1 vacuum pump series?
A The 2BE1 series supports two transmission methods: Direct connection and V-belt drive. Smaller models (103–203) typically use direct connection, while larger models offer both options depending on required speed and power.
Q How should I select the appropriate motor power for my application?
A The standard motor power listed covers most operating conditions. If the exhaust port pressure is elevated (0.02–0.05 MPa), you should select a higher motor power. Conversely, if actual shaft power is lower than rated during normal operation, choosing a motor closer to the actual shaft power improves energy efficiency.
Q Which 2BE1 model is suitable for high-volume exhaust applications?
A For high-volume exhaust requirements, the 2BE1 403 model is the top choice, offering a maximum exhaust volume of up to 123 m³/min with a motor power of 200 KW and a DN300 pipe diameter.
Q What pipe diameter does the 2BE1 103 model use, and how does it compare to larger models?
A The 2BE1 103 uses a DN65 intake and exhaust pipe diameter. As models scale up, pipe diameters increase accordingly — from DN100 and DN125 for mid-range models, up to DN300 for the 2BE1 403 — reflecting the increased flow capacity of each model.
