ⓘ Important Notes

1. 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.
2. The performance tolerance is ±10%.
3. 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 it is operating normally, a motor power closer to the shaft power can be selected, which is more energy-efficient.

❓ Frequently Asked Questions

Q What does the model number of the 2BE1 series vacuum pump indicate?

The model number of the 2BE1 series liquid ring vacuum pump identifies both the product series and the impeller size. For example, in 2BE1 252, "252" refers to the specific impeller diameter group, which determines the pump's capacity range, pipe diameter, and applicable power options.

Q Under what standard conditions were the performance parameters in the table measured?

All performance data in the table was obtained with saturated air as the intake medium at 20℃, a working fluid (water) temperature of 15℃, and an exhaust pressure of 1013 mbar. Actual performance may vary if operating conditions differ from these standards.

Q What is the limit vacuum level achievable by the 2BE1 series pumps?

All models in the 2BE1 series listed in this table achieve a limit vacuum level of -0.098 MPa (3300 Pa), making them suitable for applications requiring deep vacuum conditions.

Q What transmission methods are available for the 2BE1 series vacuum pumps?

Two transmission methods are available: Direct connection and V-belt drive. Direct connection offers higher mechanical efficiency and lower maintenance, while V-belt drive provides flexibility in speed adjustment and is commonly used for larger capacity configurations.

Q How should I select the correct motor power for my 2BE1 vacuum pump?

The motor power listed in the table is sufficient for most standard working conditions. If your application involves a higher exhaust port pressure (between 0.02 – 0.05 MPa), you should select a higher motor power. Conversely, if the actual shaft power during normal operation is relatively low, choosing a motor closer to the actual shaft power will result in better energy efficiency.

Q What is the allowable performance tolerance for the 2BE1 series pumps?

The stated performance parameters carry a tolerance of ±10%. This means actual exhaust volume and power consumption may vary slightly from the published values due to manufacturing tolerances and real-world operating conditions.
