2 BV series water ring vacuum pumps is used in taking out gas and water vapor, inspiratory pressure can reach 33 mbar absolute pressure (97% vacuum degree). When the water ring vacuum pumps in inspiratory pressure limits of working liquid vacuum (saturated steam pressure) for a long time, should work under cavitation protection tube connection to the pump to protect. As the compressor used, the greatest pressure to 0.26 MPa (absolute pressure). 2 BV series water-ring vacuum pump as a new generation of energy-saving products, and the excellent performance and numerous advantages will be fully replace with performance SK, 2 SK series water ring vacuum pumps and W, WY, WL reciprocating vacuum pump series.
