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.
