2BE1 Water Ring Vacuum Pump
High-Efficiency Oil-Free Industrial Vacuum Equipment with Steam Water Separator Design
Product Description
The 2BE1 series water ring vacuum pump is a high-efficiency, energy-saving product developed by our company using advanced imported technology. This single-stage, single-acting vacuum pump features a simple structure, convenient maintenance, reliable operation, and high energy efficiency. It is designed to extract air and other gases insoluble in water that are free of solid particles and non-corrosive, creating vacuum conditions in closed containers. When equipped with appropriate motors, it can handle flammable and explosive gases. With corrosion-resistant materials, it can also process corrosive gases to a certain extent.
Applications
Widely used across multiple industries including power generation, chemical processing, coal mining, paper manufacturing, plastic machinery, environmental protection, medical, food processing, mineral processing, petrochemical, light industry, packaging, metallurgy, building materials, stone processing, and fertilizers. Typical applications include vacuum filtration, vacuum feeding, vacuum degassing, vacuum evaporation, vacuum concentration, vacuum moisture regain, coal mine gas drainage, and chemical plant pressure swing adsorption. Particularly suitable for applications requiring large air volume, high vacuum degree, and isothermal compression of flammable and explosive gases.

Frequently Asked Questions
Q1. Can the 2BE1 series be used as a compressor?
Yes, it can be configured as a compressor when needed, with a maximum discharge pressure of 0.26MPa (absolute pressure) for low-pressure compression scenarios.
Q2. What is the difference between the 2BE1 and 2BE3 series?
The 2BE3 series offers larger air volume but lower vacuum degree, making it suitable for high-volume applications. It uses double-row tapered roller bearings and features optimized positioning between the pump body and distribution plate with more installation options.
Q3. Is there a MOQ limit for this product?
No, the minimum order quantity is 1 unit, supporting sample testing and small-batch procurement.
Q4. How to choose the right motor power?
The motor power in the parameter table suits most working conditions. For high exhaust pressure or harsh conditions, increase motor power appropriately. If actual shaft power is low, select a motor close to the shaft power for energy efficiency.
Q5. What materials are available for the flow passage parts?
Standard configuration is cast iron with stainless steel impeller; full stainless steel flow passage parts are available for corrosive working conditions.
Q6. What is the warranty period of the 2BE1 series?
We provide a 1-year warranty covering manufacturing defects and component failures (excluding wear parts and damage caused by improper use or unconfigured special working conditions).
Q7. How to solve cavitation during operation?
The pump includes precise anti-cavitation protection measures. When operating under extreme pressure, connect the cavitation protection pipe or increase working fluid flow to eliminate cavitation noise.
Q8. Can the transmission mode be customized?
Yes, most models support both belt drive and direct motor connection; please specify the required transmission mode when ordering.
Q9. What is the service life of key components such as bearings and mechanical seals?
Imported bearings have a service life of approximately 15,000 hours, and imported mechanical seals last about 8,000 hours under normal working conditions. Regular maintenance can extend component life.
Q10. How to confirm the model selection?
Please provide parameters such as required pumping speed, vacuum degree, medium type, working temperature, and transmission mode, and our technical team will recommend the suitable model.
