Bvc series water ring vacuum pump and compressor is mainly used for sucking gases and water vapour. The ultimate suction pressure can reach 33mbar (97% vacuum). When working under suction pressure below 80mbar long time, it should be connected with cavitation resistant pipe. The suction pressure can reach 10mbar if assembling with an air ejector. As a compressor, the ultimate pressure can reach 0.26mpa. Characteristics: 1. Motor:inline, direct connection with the pump, saving space and easy to install. 2. Mechanical seal: no leakage and easy to maintain. 3. Firm performance and low noise (can be as low as 62 db(a)) 4. Bronze impeller improves the corrosion resistance; stainless steel vacuum pump can meet higher requirements for corrosion resistance. 5. Special flexible outlet design ensures no over-compressing and firm performance under design conditions.
