Type D、DL multi-grade pumpis ahorizontal single-absorbing multi-section centrifuge one whichto transfer cleanwater(impurityless than 1%)andthe other corrosive liquid whosephysic features is similar to clean water according todifferent rawmaterials.D、DLtype pump made by common materials is only to transfer the medias whose temp.No—ore than 20℃,and one by special materials,the neutral or little corrosive liquid,or clean or little particle's one in the lineof chemical,pharmaceutical,petrol,metallurgy,and environment,etc.

Model FCDLvertical long shaftpump series adopts submergedblade wheel and vertical installationstructure.It hasmerits ofcompact structure,stable running,easy operation,convenient maintenance,small ground space,high degr-ee of versatility and standardization.Itis an up-to-date mature product series researched and developed by our comp-any on the basisof absorption of advanced experiences on design and manufacture ofvertical long shaftin the devel-oped countries with accommodationto the domesticmarket requirements.

The product has many applications including industrial water supply and drainage,tap water of city,living water andfire-fighting water,water pumping from river,Iake and sea.Itis used in industriesof metallurgical,mine,chemical,pa-permaking,water power station,etc

The SG type series piping pump increases to pres the water for high buidings,solution piping pressure overlow but the single-stage-single-suction in new the type of upright that research to manufacture leaves the heart pups,comparing the curent applied the typeofhōrizontal leave the heart pump has the bigger andsuperior.Because the advanced machine in adoption seals compietely,the el-ctricalengineering principal axis adds to connect,the stalk presses to packleaf's round.So there islitle leakage.The efiency is h-

igh.Consume to give or get an electric shock the province.Construction tightly packed the physical volume is small.The weight islig-ht.Repair the convenience,Combining can adopt with the demand of the discharge to combine to establish usageetc,characteristicsaccording to the distance of head.
