Abstract: Pump is a mechanical device which uses suction or pressure to raise liquids. Pump casing assembly consists of single or multiple stages to meet exact system head requirements. A wide range of casing sizes are available to meet the system capacity requirements. Standard construction includes iron casing with bronze impellers on a stainless steel pump shaft. The Main problem associated with ductile iron casing is corrosion, because it will be immersed in water during operations. In this research work an attempt has been made to replace the metallic casing of multistage submersible pump with ABS material. First the geometric modeling of six stage pump is carried out using modeling package CATIA V5.Then the model is imported to preprocessor solver hyper mesh, here finite element model of ductile iron and ABS is generated. After that FE model is imported in to ABAQUS V6.12 solver to carry out the static analysis for different pressures. The von mises stress developed for both the casings are compared. Water flow simulation inside the pump casing for ductile steel and ABS material for different pressures is simulated using Solid WorksV11 solver. The maximum velocity distribution obtained for both materials are same. The prototype model of ABS pump casing is manufactured using FDM technique, this model is tested for physical properties using shore durometer. The obtained hardness values compared with ductile steel casing. Analysis results show that ductile iron can be replaced by ABS as it possesses good corrosion resistance and light weight.
