2BV series water ring vacuum pumps are used to pump the gases and steam. Its suction pressure can reach 33mbar (abs) (i.e. 97 per cent vacuum degree). When the liquid ring vacuum pumps are working 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 compressor . 2BV series water ring vacuum pumps and compressors will replace the SK and 2SK series water ring pumps and the W, WY, WL series reciprocated vacuum pumps completely with their superior performance and advantages.
2BV2-Ex and 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 with the 2BV2 or 2BV5 series products.
