2BV Series Liquid Ring Vacuum Chenmical Industrial Pump

Description :

2BV series Liquid ring vacuum pumps are suitable for pumping gases and steam . Its suction pressure can reach 33mbar (abs) ( i.e. 97 % vacuum degree ) . lf 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 neaithe limited vacuum for a long time , we will add our cavitations protection pipe to get rid of the screaming and protect the pump. When the compressors work , the maximum pressure is 0.26MPa (abs) . And the discharge pressure is higher , the power is bigger . So it is necessary to get the data of the discharge pressure is to choose the proper motor. 2BV series liquid 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 , 2BV6 series Liquid 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 0corresponding type of the 2BV2 or 2BV5 series products.

Material :

2BV series stainless steel pumps can be used under the conditions with higher requirements for the corrosive-proof or theustration, According to the working situation, the material of all the parts where the liquid flows (i.e. pump casing, pumpcover,port plate,impeller)are made ofvarious stainless steelas bellow: SUS304(0Cr18Ni9) SUS316(0Cr17Ni12Mo2) SUS316L(00Cr17Ni14Mo2) The materialofthe shaft is 2Cr13 or 0Cr18Ni12Mo2Ti The mechanical seals are used the Chinese brand products and the seals material is optional for FPM or PTFE
