Product Characteristics

High efficiency and low energy consumption

The flexible exhaust design, single-stage impeller structure, and imported technology enable the 2BE water ring vacuum pump to save 20% energy when in use.

Long service life

The designed service life is 20 years. Different materials of 2BE water ring vacuum pumps can be selected based on the pumping medium, such as carbon steel, stainless steel 304, 316L, 904L, 2205, 2507, etc.

Equipped with explosion-proof motors

Equipped with explosion-proof motors, capable of extracting explosive gases, and working in various flammable and explosive environments.

Long-lasting

As the core component of the non-rotating water ring vacuum pump, the impellers are all made of ductile iron QT400 or welded steel plates, fully ensuring the stability of the 2BE water ring vacuum pump impellers under various harsh working conditions. The pump body is also all made of welded steel plates, significantly increasing the service life of the 2BE vacuum pump.

📋 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

🔹 What is the limit vacuum level of the 2BE1 series liquid ring vacuum pump?

The limit vacuum level for the entire 2BE1 series is -0.098 MPa (approximately 3300 Pa). This high vacuum performance applies to all models listed in the specification table, from the 2BE1 103 up to the 2BE1 403.

🔹 Under what conditions were the performance parameters measured?

All performance parameters in the table were obtained with saturated air as the intake medium at 20℃, a working fluid temperature of 15℃, and an exhaust pressure of 1013 mbar. Results in real operating environments may vary by up to ±10%.

🔹 What transmission methods are available for the 2BE1 vacuum pump?

The 2BE1 series supports two transmission methods: direct connection and V-belt drive. Smaller models such as the 2BE1 103 and 2BE1 153 use direct connection, while larger models often offer both options depending on required pump speed and power configuration.

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

The motor powers listed in the table are suitable for most standard operating conditions. If the exhaust port pressure is elevated (0.02–0.05 MPa), you should select a higher motor power. Conversely, if the pump's shaft power is significantly lower than rated during normal operation, choosing a motor closer to the actual shaft power will improve energy efficiency.

🔹 What pipe diameter should I use for the 2BE1 403 model?

The 2BE1 403 requires DN300 intake and exhaust pipe diameters. This is the largest pipe size in the 2BE1 series, reflecting the pump's higher capacity range of 95–123 m³/min and power options of 132–200 kW.

🔹 Which 2BE1 model offers the highest exhaust volume capacity?

The 2BE1 403 model provides the highest maximum exhaust volume in the series, reaching up to 123 m³/min at 472 r.p.m with a 200 kW motor. It is ideal for large-scale industrial applications requiring high vacuum flow rates.
