I. Core Capabilities
High-Efficiency Pumping
The 2BV series water-ring vacuum pump is designed to evacuate gases and water vapor, achieving an ultimate suction pressure of 33 mbar (absolute pressure, 97% vacuum). When using transformer oil as the working fluid (oil-ring pump mode), this can be further improved to 6.7 mbar (absolute pressure, 99.3% vacuum), serving as a complete replacement for traditional reciprocating vacuum pumps.
Versatile Application
Widely used in sectors such as chemicals, pharmaceuticals, food processing, vacuum packaging, and mine gas extraction; particularly suitable for environments with flammable or explosive gases (e.g., models equipped with explosion-proof motors).
II. Technical Advantages
Energy-Efficient Design
Close-coupled structure: Coaxial direct-drive design minimizes energy loss and boosts operating efficiency by over 20%.
Flexible discharge port: Unique design prevents over-compression, ensuring optimal energy efficiency across the performance range.
Durable Materials
Aluminum-bronze impeller: High strength and superior corrosion resistance extend equipment service life.
Stainless steel/cast iron options: Adaptable to various media requirements, such as corrosive chemical environments.
Low Noise & Eco-friendly
Operating noise as low as 62 dB; compressed gas temperature is only 10–15°C higher than the inlet temperature, making it suitable for sensitive process environments.
III. Structural & Operational Advantages
Compact & Easy to Install
Integrated design saves space; requires only horizontal leveling for installation, eliminating the need for complex foundation work.
Easy Maintenance
Imported mechanical seals: Standard configuration reduces leakage risk and maintenance frequency.
Modular components: Can be combined with separators, heat exchangers, and other units to form complete systems, flexibly adapting to production line needs.
IV. Industry Solutions
Chemical/Pharmaceutical Sectors
Corrosion-resistant materials and explosion-proof designs meet GMP standards; suitable for processes such as vacuum drying and distillation.
Food Processing
Low-temperature operation and oil-free characteristics make it ideal for vacuum packaging, concentration, sterilization, and more.
Mining/Energy
High vacuum capability ensures stable gas extraction; equipped with cavitation protection piping to guarantee long-term safe operation. With its comprehensive performance—characterized by energy efficiency, stability, and durability—the Boshan Zhongli 2BV water ring pump has become a benchmark in the industrial vacuum sector; its modular design and broad adaptability provide efficient solutions for a wide range of industries.
