2BV  liquid ring vacuum pump
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.
series water ring vacuum pumps and compressors will replace theSK and 2SK

series water ring pumps and the W, WY, WL series reciprocated vacuum
pumps completely with their superior performance and
advantages.
