The 2BE3 water ring vacuum pump is a widely used industrial vacuum equipment designed for applications in chemical processing, power generation, mining, papermaking, pharmaceuticals, and other industries. The series features high pumping capacity, stable operation, and strong adaptability. Different models and speeds can be selected according to specific operating conditions to meet the vacuum requirements of large-scale industrial systems.
The 2BE3 series water ring vacuum pump includes various models, such as 2BE3 400, 2BE3 420, 2BE3 500, 2BE3 520, 2BE3 600, 2BE3 620, 2BE3 670, and 2BE3 720.
According to the product technical specifications, the 2BE3 400 can achieve a maximum suction capacity of 8,600 m³/h (143.3 m³/min), while the larger 2BE3 720 can reach up to 38,100 m³/h (635 m³/min), providing suitable solutions for industrial vacuum systems of different capacities.
The 2BE3 series offers multiple drive speed configurations. Different models can be equipped with suitable speeds, motor power, and shaft power according to actual operating conditions, helping achieve efficient equipment matching.
For example, the motor power of the 2BE3 400 ranges from 110 to 220 kW, while the 2BE3 720 can be equipped with motor power ranging from 400 to 900 kW, making it suitable for large industrial production lines and high-capacity vacuum systems.
According to the product specification table, the limiting vacuum of the series can reach 160 mbar (abs). Different models can provide different suction capacities through various speed and motor configurations.
The 2BE3 series uses a water ring operating principle. The working liquid forms a water ring inside the pump chamber to compress and discharge gas, making the pump suitable for various industrial vacuum applications.
The available models cover multiple specifications:
· 2BE3 400: Maximum suction capacity of 8,600 m³/h
· 2BE3 420: Maximum suction capacity of 11,600 m³/h
· 2BE3 500: Maximum suction capacity of 15,500 m³/h
· 2BE3 520: Maximum suction capacity of 18,700 m³/h
· 2BE3 600: Maximum suction capacity of 21,600 m³/h
· 2BE3 620: Maximum suction capacity of 26,200 m³/h
· 2BE3 670: Maximum suction capacity of 30,960 m³/h
· 2BE3 720: Maximum suction capacity of 38,100 m³/h
The weight of each model also varies. For example, the 2BE3 400 weighs approximately 3,275 kg with separator, while the 2BE3 720 weighs approximately 15,700 kg. Therefore, equipment selection should take installation space, required pumping capacity, and supporting equipment into consideration.
With its high pumping capacity, the 2BE3 water ring vacuum pump is suitable for large industrial vacuum systems. It can be used for vacuum distillation, vacuum filtration, gas extraction, vacuum dewatering, and other industrial processes.
In papermaking, pharmaceutical, and other manufacturing processes, the water ring vacuum pump can be used for dewatering, filtration, and vacuum drying. Selecting the appropriate 2BE3 model according to the required vacuum level and pumping capacity can help improve system efficiency.
When selecting a 2BE3 water ring vacuum pump, key factors include required pumping capacity, limiting vacuum, operating speed, motor power, and working medium. For large industrial vacuum systems, equipment weight, installation conditions, and supporting separators should also be considered.
Choosing the right model can help meet process requirements while reducing energy consumption and long-term operating costs. Professional selection based on actual operating conditions is essential for ensuring stable and reliable operation of the 2BE3 water ring vacuum pump.
