One of low cost alternatives of small hydropower resources is the use of pumps as turbines. The action of pump operates like water turbine when it is run in reverse. Standard pump units when operated in reverse have important advantages over conventional turbines for small scale hydropower generation; i.e. mass production of pumps while turbines are designed for a specific purpose, available for a wide range of heads and flows, available in large number of sizes, low cost, spare parts are easily available and easy installation. Tests shoed that pumps operating as turbine could compete with turbines, with high efficiency in range of relatively small power.<p>The objective of the study was to abtain a data acquisition software which is used to evaluate the 200 SZ pump as turbine systems in terms of performance as to capacity and efficiency. During the performance test, this software are really helpful in getting more data so the result will can be statistically responsibled. Evaluation of the 200 SZ pump as turbine showed that the modificated impeller has better efficiency than the original. The result is found from similarity law of turbine with 250 SZ pump as turbine. From test result, efficiency is lower than efficiency with similarity. Therefore more research must be done to improve the performance and optimizing the operation of pump as turbine.
