In recent years, the use of turbines or pumps operating as turbines (PATs) has been proven to be a sustainable alternative for micro hydro plants. The off-the-shelf availability of water pumps and economic and technical advantages for installation, operation, and maintenance with respect the traditional turbines would make them an ideal technology for exploiting large portions of untapped hydro potential. However, pump as turbine (PAT) faces the problem of part load efficiency, which is a hurdle to a more widespread PAT implementation. In order to overcome this limitation, an attempt has been made to modify the centrifugal pump by providing guide vane around the impeller. Under the present study, this modified pump running in reverse mode is investigated experimentally. On the basis of results, it has been found that modified PAT yields better part load efficiency.
