2BV series water ring vacuum pump
is a single stage coaxial pump with integral structure. The shaft seal adopts mechanical seal, which has the characteristics of simple structure, simple installation, no oil, safety and reliability.
2BV series water ring vacuum pumps are suitable for pumping gas and wet steam. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When 2BV type water ring vacuum pumps work for a long time under the condition of suction pressure below 80 mbar, they should be connected with cavitation protection tubes to protect the pumps. 2BV type water ring vacuum pumps with atmospheric ejector suction pressure can reach 10 mbar, and ejectors can be installed directly in the real situation. When the air pump suction port is used as a compressor, its maximum pressure is 0.26 MPa (absolute pressure).
2BV series water ring vacuum pumps and compressors are widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields. Because the compression process of gas is isothermal in the working process, it is not easy to explode when compressing and sucking inflammable and explosive gas, so it is more widely used.
