The 2BV series liquid ring vacuum pump is engineered for pumping gases and water vapor, achieving a suction pressure of 33 mbar absolute (97% vacuum). It is designed for longevity and efficiency. When suction pressure is maintained below 80 mbar for extended periods, a cavitation protection tube can be connected to ensure pump safety. If paired with an atmospheric injector, suction pressure can reach up to 10 mbar.
