One Stage Water Ring Vacuum Pump is suitable for pumping gas and steam. Its suction pressure can reach 33 mbar (ABS) (97% vacuum). If transformer oil is used as working liquid, these pumps are called oil ring vacuum pumps, and the suction pressure can reach 6.7 mbar (ABS) (i.e. the vacuum degree is 99%). Therefore, the oil ring vacuum pump can completely replace the reciprocating vacuum pump. When the liquid ring vacuum pump works for a long time under the condition of close to the limit vacuum, it is necessary to connect with the cavitation protection pipe to eliminate the scream and protect the pump.

 
When the compressor is working, the maximum pressure is 0.26mpa (ABS). The higher the discharge pressure, the greater the power of the compressor. Therefore, exhaust pressure data must be provided to select the appropriate motor.
 
2BV series water ring vacuum pump and compressor will completely replace SK and 2SK series water ring pump and W, WY, WL series reciprocating vacuum pump with its superior performance and advantages.
 
One Stage Water Ring Vacuum Pump and compressor are mainly used to pump explosive gas or work in flammable and explosive environment. The technical parameters of each type are the same as the corresponding types of 2bv2 or 2bv5 series products.
