Performance Parameter 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 numbers in the 2BE1 series (such as 2BE1 103, 2BE1 252, 2BE1 403) represent different pump sizes and performance tiers. Higher model numbers generally correspond to larger impeller diameters, greater exhaust volumes, and higher motor power ratings, allowing users to select the appropriate unit based on their specific process requirements.

Q What is the limit vacuum level that the 2BE1 series pumps can achieve?

All models in the 2BE1 series share a common limit vacuum level of -0.098 MPa (3300 Pa). This consistent performance across the range makes the series suitable for a wide variety of industrial vacuum applications requiring stable, deep vacuum conditions.

Q What are the differences between V-belt and direct connection transmission methods?

V-belt transmission allows for flexible speed adjustment and provides some vibration dampening between the motor and pump, making it suitable for variable-speed operating conditions. Direct connection (coupling) offers a more compact layout, higher transmission efficiency, and lower maintenance requirements. The appropriate method depends on the required pump speed, installation space, and operational environment.

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

The listed performance parameters were measured using saturated air as the intake medium at 20℃, a working fluid (water) temperature of 15℃, and an exhaust pressure of 1013 mbar (standard atmospheric pressure). A performance tolerance of ±10% applies to all listed values.

Q How should I select the correct motor power for my application?

The motor power listed in the table is suitable for most standard operating conditions. If your application involves a high exhaust port pressure (0.02–0.05 MPa), you should select a motor with higher power than listed. Conversely, if the pump's shaft power is measurably lower than the motor rating during normal operation, selecting a motor closer to the actual shaft power will improve energy efficiency and reduce operating costs.

Q What intake and exhaust pipe diameter should I use for my selected pump model?

Each pump model specifies a standard pipe diameter for its intake and exhaust connections — ranging from DN65 for the 2BE1 103 up to DN300 for the 2BE1 403. It is important to match your piping system to the specified diameter to ensure optimal flow rates, minimize pressure losses, and maintain the pump's rated performance.
