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 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 limit vacuum level of -0.098 MPa (3300 Pa) mean for the 2BE1 series vacuum pump?
The limit vacuum level of -0.098 MPa (3300 Pa) represents the lowest absolute pressure the pump can achieve under ideal operating conditions. This means the pump can evacuate a system to near-vacuum, making it suitable for demanding industrial applications such as paper pulp processing, chemical degassing, and power plant condenser evacuation.
Q
What is the difference between V-belt and direct connection transmission methods in the 2BE1 series?
Direct connection (coupling drive) offers higher transmission efficiency, lower maintenance, and is preferred for continuous high-load operations. V-belt drive allows flexible speed adjustment and acts as a protective buffer against shock loads, making it suitable for applications where pump speed needs to be tuned or where motor and pump shaft alignment is more variable.
Q
Why does the same pump model (e.g., 2BE1 252) have multiple power and speed options?
Different power and speed configurations for the same model allow users to select the most suitable operating point based on their required exhaust volume and system pressure conditions. Higher motor power and speed deliver greater exhaust capacity, while lower configurations offer energy savings when full capacity is not required.
Q
Under what test conditions were the performance parameters in the table measured?
All performance parameters were measured using saturated air as the intake medium at an inlet temperature of 20℃, a working fluid (seal 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
When should I consider increasing the motor power beyond the standard specification?
If your application requires the exhaust port to operate at elevated back pressure — typically between 0.02 MPa and 0.05 MPa above atmospheric — the pump requires more shaft power than under standard conditions. In such cases, you should select a motor with higher power than listed in the standard table to prevent motor overload and ensure reliable long-term operation.
Q
How do I select the right pipe diameter for my 2BE1 vacuum pump installation?
The intake and exhaust pipe diameters listed in the table (ranging from DN65 to DN300) correspond to the nominal connection size of each pump model. You should match the piping to the pump's specified diameter to avoid excessive flow resistance or pressure losses. For larger models such as the 2BE1 403, a DN300 pipe is required to handle the significantly higher exhaust volumes of up to 123 m³/min.
