The main objective of this paper is to design a double-suction centrifugal pump which can produce hydraulic energy by using water pressure. The double-suction centrifugal pump is chosen because it can widely use in the field of municipal water works, drainage system, power plants, agriculture, irrigation work and many other utility services and industries. A centrifugal pump includes an impeller mounting on a shaft coupled to the driving unit. The impeller comprises a central hub on which the curved vanes are mounted. The unit has a finite number of vanes; the number of vanes is selected to assure motion of the liquid in the desired direction varies with the specific speed. A centrifugal pump consists essentially of rotating element, stationary element, suction pipe and delivery pipe. In this research, dimensions are calculated for the design point of 45 m head, 25m³/min of flow rate and rotational speed of 1450 rpm. The inner diameter of impeller is 297 mm and the outer diameter is 471 mm. The passage width at inlet is 50 mm per side and total passage width at outlet is 80.838 mm. The blade angles at inlet and outlet are 13.31˚ and 20˚ respectively. The number of blades is eight. The design of volute is based on the impeller outside diameter and impeller outlet width. In this design, volute circle diameter is 546 mm, volute width is 88 mm and volute casing is horizontal split type.
