Abstract: This paper presents the calculation and production procedure of impeller for single section centrifugal pump. The pump type is single stage centrifugal pump with close impeller type. This impeller develops a head of 20 m and delivers 0.9 m3 /min of water. The designed impeller has 97 mm inlet diameter, 226 mm outlet diameter, 20˚ inlet vane angle and 23˚ outlet vane angle. The total number of vane is 6 and input shaft power is 6 hp. The inlet and outlet width are 26 mm and 18 mm respectively. The discharge pipe diameter is 80 mm to operate the desired head and capacity.
