**2BV Series Liquid Ring Vacuum Pump Overview**
The 2BV series liquid ring vacuum pump, manufactured by Denair, includes models such as 2BV5, 2BV2, and 2BV6. These pumps exceed industry standards with outstanding performance and are widely used in pharmaceuticals, plastic machines, chemicals, oil and gas, and other industries for suction applications.
Denair’s 2BV series is designed with a compact structure, making it ideal for installations where space is limited. The rotors of the 2BV2 and 2BV5 models are directly mounted on the motor shaft without any connectors, and the pump case is installed directly on the motor casing, eliminating the need for alignment. Standard configurations include a bronze impeller that enhances corrosion resistance and a mechanical seal that prevents leakage and reduces maintenance requirements. The flexible vent design ensures optimal operation efficiency, while the 2BV6 model, constructed from stainless steel, performs better in harsh environments.
