Product Description

Product Description

I. Technical Principles and Structural Advantages
Working Mechanism
The impeller rotates eccentrically, driving the working fluid (water) to form a water ring. Gas intake and compression are
realized through the volume change of the crescent-shaped space between the blades and the water ring. During compression, the working fluid exchanges heat with the gas to achieve isothermal compression, making it suitable for handling flammable and explosive gases.
Structural Design
* Coaxial Direct Drive: The motor and pump body are integrated without a coupling, saving 50% installation space, with low
vibration (noise ≤70dB).
* Flexible Exhaust Port: Prevents over-compression, improving efficiency by 10%-15% in the high-vacuum range (e.g., 33 mbar).
* Material Adaptation: * Standard: Aluminum bronze impeller + cast iron pump body (resistant to weak acids and mild corrosion);
* Upgraded: Full stainless steel (SUS316L)/fluorine-lined material (resistant to strong acids and organic
solvents).
II. Key Performance Parameters
Vacuum and Flow Rate
* Ultimate Vacuum: Single-stage up to 33 mbar (absolute pressure, approx. -0.097 MPa); two-stage + ejector 6.7 mbar.
* Suction Rate: 0.81-231 m³/h (covering models from 2BV2060 to 2BV2076).
Energy Consumption and Adaptability
* Motor Power: 0.81-185 kW, supporting variable frequency control (energy saving of 30%).
* Working Fluid Flow: 2-50 L/min, closed-loop system saving 80% water.
* Interfaces: DN25-DN150 pipe diameter; explosion-proof type (2BV2-Ex) complies with ATEX certification (Zone 0 environment).
