Vacuum Pump, Single Stage Water Ring Vacuum Pump, 2BV5121 Vacuum Pump

2BV series water ring vacuum pumps are suitable for pumping the gases and steam. Its suction pressure can

reach 33mbar (abs) (i. E. 97 % vacuum degree). If the transformer oil is used as the operating liquid,

these pumps are called oil ring vacuum pump and the suction pressure can reach 6.7mbar (abs) (i. E. 99 %

vacuum degree). So the oil ring vacuum pumps can replace the reciprocated vacuum pumps completely. When

the liquid ring vacuum pumps work under the condition near the limited vacuum for a long time, it is

necessary to couple with the cavitation protection pipe in order to get rid of the screaming and protect

the pump.
When the compressors work, the maximum pressure is 0.26MPa(abs). And the higher of discharge pressure,

the larger of the power of the compressors. So it is necessary that the data of the discharge pressure

is provided to choose the proper motor.
