ABSTRACT

The study was undertaken to determine the performance of submersible pump and mono-block centrifugal pump to develop characteristic curves of and its operating conditions. The results revealed that submersible pump the maximum all over pump set efficiency was found 54.98 % at working head 40.43 m, discharge equal to 24.10 lps, WHP 12.99 and input HP 23.63, it was operating point of pump. More than 50 % efficiency can be achieved with discharge capacity varied between 24.10 to 17.89 lps. While Mono-block pump testing was done for suction lifts 0.5 m, 0.7 m, 1.6 m and 2.5m, the maximum efficiency was found 75.10 % at 0.7 m suction lift and at 29.34 m head under same static lift minimum efficiency was found 47.94 .So, operating head may be adopted 17 m against this head maximum efficiency is 48 %, discharge 11.9 lps and 5.5 HP
