**2BV Series Liquid Ring Vacuum Pump Overview**
The 2BV series liquid ring vacuum pump, manufactured by Denair, includes the 2BV5, 2BV2, and 2BV6 models. These pumps are known for their exceptional performance, exceeding industry standards and widely used in applications such as pharmaceuticals, plastic machines, chemical processing, oil and gas, and marsh gas industries.
