Important 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 pumps?
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
What are the standard test conditions for the performance parameters in the table?
The listed performance data is measured using saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. Actual performance may vary under different operating conditions.
Q
What transmission methods are available for the 2BE1 vacuum pump series?
The 2BE1 series supports two transmission methods: Direct connection and V-belt drive. The choice depends on the specific model, required pump speed, and application requirements.
Q
How should I select the correct motor power for my 2BE1 vacuum pump?
The standard motor power listed covers most working conditions. If the exhaust port pressure is high (0.02–0.05 MPa), you should increase the motor power accordingly. Conversely, if the pump's shaft power is relatively low during normal operation, selecting a motor closer to the actual shaft power will improve energy efficiency.
Q
What is the maximum exhaust volume available across the 2BE1 series?
The maximum exhaust volume ranges from 5.8 m³/min (2BE1 103, 11 KW) up to 123 m³/min (2BE1 403, 200 KW), providing a wide selection to match varying process demands.
Q
What pipe connection sizes are used across the 2BE1 vacuum pump range?
Intake and exhaust pipe diameters vary by model: DN65 (2BE1 103), DN100 (2BE1 153), DN125 (2BE1 202/203), DN150 (2BE1 252/253), DN200 (2BE1 303/353), and DN300 (2BE1 403). Selecting the correct pipe size ensures optimal flow and system efficiency.
