High Quality Stainless Steel Material 2BV2060 Water Ring Vacuum Pump2BV 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 recicated vacuum pumps completely. When the liquid ring vacuum pumps work under the near the limited vacuum for a long time, it is necessary to couple with the cavitation tection pipe in order to get rid of the screaming and tect 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 vided to choose the per motor.
2BV2-Ex,2BV6 series water ring vacuum pumps and compressors are mainly used for pumping the explosive gases or work in the flammable and explosive environment. The technical parameter of each type is the same as the corresponding type of the 2BV2 or 2BV5 series ducts.
According to the working situation, the material of all the parts where the liquid flows (i.e. pump casing,pump cover, port plate, impeller)are made of various stainless steel as bellow:
SUS304(0Cr18Ni9)
