Abstrak
The hydraulic ram pump (hydram) is an automatic water-lifting device that utilizes the energy of flowing water itself to pump a portion of the water to a higher elevation. This study aims to analyze the performance of a hydram pump by examining two key parameters: the efficiency and the output flow rate (discharge). The experiment was conducted with variations in the drive head (water source height) at 100 cm and 200 cm, and by employing one or two air chambers. The results show that using two air chambers significantly improves performance. For a drive head of 100 cm, the pump efficiency increased from 1.63% with one air chamber to 29.89% with two. Similarly, for a drive head of 200 cm, the efficiency rose from 36.00% with one air chamber to 59.32% with two. The increase in efficiency is attributed to the enhanced input discharge. Furthermore, the measured output discharge using two air chambers was 0.156 L/s for the 100 cm drive head and 0.315 L/s for the 200 cm drive head. Key words: Optimization, Head, chamber, Flowrate and Efficiency.
