2BV Series liquid ring vacuum pumps and compressors
Product Description:
Overview:
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 2BV series are used as compressor, it should pay attention to the discharge pressure and select suitable motor power as the increase of the discharge pressure will increase the 2BV pump power.

Notes:Table of performance of 2BV liquid ring vacuum pumps (performance curves of compressors attached)
Click to activate the links of large figures for the performance curves. Please wait for a while if the figures appear slowly.The curve is obtained under the situation that the suction medium is saturation air at 20oC, the operating liquid at 15oC,and the discharge pressure is 1013mbar. The performance tolerance is 10%.
