**DESCRIPTION**
The 2BVA series water ring vacuum pump is a versatile and reliable solution for pumping gas and water vapor. It can achieve an absolute pressure of 33 mbar (vacuum degree of 97%), making it ideal for various industrial applications. When operating under pressures below 80 mbar for extended periods, a gas corrosion protection tube should be connected to the pump to ensure longevity. Equipped with an air injector, the pump can reach an inspiratory pressure of 10 mbar, which can be directly installed on the unit. As a compressor, it can handle up to 0.26 mbar (absolute pressure).

**WORKING THEORY**
The 2BVA series vacuum pump is designed for efficient operation in environments where gas and water vapor need to be removed. The pump maintains a stable and consistent performance, even under challenging conditions. Its design allows for smooth and quiet operation, minimizing noise levels to as low as 62 decibels. The use of a bronze impeller enhances corrosion resistance, while stainless steel components are suitable for more demanding applications. The unique flexible vent design prevents over-compression, ensuring optimal efficiency within the pump’s performance range.
