Design, Fabrication and Testing of Hydraulic Turbine Runner for a Double Suction Centrifugal Pump in Turbine Mode

Mark D. Villanueva and Joffrey E. Hapitan
Abstract—A double suction centrifugal type of pump was converted into a hydraulic turbine (PAT-Pump Acting as Turbine). The casing was maintained and the pump impeller was replaced by a hydraulic runner. It was made of stainless steel with a diameter of 0.662 meter. It had 12 blades as compared to the 5 blades of the original pump impeller. It was assembled inside the original pump casing and was installed along the existing 0.9 m diameter water pipeline of the Rio Verde Water Consortium Inc. Water Treatment Plant has an elevation of around 100 meters above sea level. A bypass line was connected along the existing pipeline to accommodate the installation of the PAT. A portion of the water flowing along the main line was diverted to the bypass line to drive the PAT then flow back to the main line. This gave variation of water flow rates through the PAT by controlling the opening and closing of the valves without altering the total flow rate along the main line. The PAT was commissioned and its operation was observed and tested as to its performance for more than one month. The lowest recorded PAT efficiency was 29% generating electrical power of 5.5 KW, effective head of 7 m. and flow rate of 1311 cu.m. per hr. The electric generator used was an electric motor running in reverse with an efficiency of around 85%. The highest recorded PAT efficiency was 69% generating electrical power of 16 KW, effective head of 7m. and flow rate of 1439 cu.m. per hr.

Index Terms—PAT-pump acting as turbine, hydraulic runner, solidworks.
