Product Description
Vacuum Pump - Water Ring Series
2BV series water ring vacuum pump is suitable for pumping gas and water vapor, the ultimate pressure can reach absolute pressure 3300pa (97% vacuum). The working fluid can be recycled using the pumped medium to form a closed cycle system, achieving zero emissions and solvent recovery.
When operating near ultimate vacuum, a cavitation protection pipe is connected to protect the pump. For compressor applications, outlet pressure can reach up to 0.26Mpa (absolute pressure). The 2BV2-EX and 2BV6 series are specifically designed for explosive gases and flammable environments.
Main Features
- Machine pump coaxial or direct connection design for space-saving and easy maintenance.
- Standard mechanical seals completely eliminate leaks.
- Cavitation protection interface to eliminate cavitation noise and protect components.
- Corrosion resistance: Parts available in SUS304, SUS316L, 2205, 2507, titanium for acid/alkaline gases.
- Unique flexible exhaust port design ensures optimal operating efficiency across the vacuum range.
