2BV series liquid ring vacuum pump is suitable for gas and water vapor extraction. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When the suction pressure of liquid ring vacuum pump is close to the limit vacuum (saturated vapor pressure of working fluid), the cavitation protection pipe should be connected to protect the pump. When used as a compressor, the maximum pressure is 0.26 MPa (absolute pressure).
