SPECIFICATION

Product Name: 2BVA Series Water Ring Vacuum Pump

WORKING THEORY
The 2BVA series vacuum pump is designed for pumping gases and water vapor, capable of reaching a vacuum level of 33 mbar (equivalent to 97% vacuum).
When operating under pressure lower than 80 mbar for extended periods, it's recommended to connect a gas corrosion protection tube to protect the pump.
Equipped with an air injector, the pump can achieve an inspiratory pressure of 10 mbar, which can be directly installed on the pump itself.
When used as a compressor, the maximum pressure can reach 0.26 mbar (absolute pressure).

ADVANTAGES

1. Coaxial design with direct motor connection, saving space and making installation easier;

2. Standard mechanical seal configuration to prevent leakage and simplify maintenance;

3. Smooth operation with noise levels as low as 62 dB(A);

4. Uniform anti-corrosion design with bronze impeller to enhance corrosion resistance;

5. Stainless steel construction for more demanding environments;

6. Unique flexible vent design prevents over-compression, ensuring optimal efficiency within performance range.
