Analysis of Hydram Pump Performance on Variation of Installation on Various High Waterfalls

Water is one of the factors which very important and necessary in the life of living creatures. Therefore, water must be available whenever and wherever in the quantity, timing, and sufficient quality. Hydraulic Ram Pump (Hydram) is a pump which does not require external energy as the power source. In this study, a hydram pump with an input diameter of 1.5 inches, an output diameter of 0.5 inches and a diameter of a compressor tube 3 inches with a height of 60 cm. The height variations in the waterfall used were 2.1 m, 2.6 m, 3.1 m, 3.6 m, and 4.1 m. As for variations in the position of the hydram pump arrangement with the installation position of input-waste-compressor (ILK) and input-compressorwaste (IKL). This study results that the highest output discharge is generated at a height of 4.1 meters with an ILK arrangement of 0.121 L/s. The highest maximum head is obtained at a height of 4.1 meters in the ILK arrangement of 16 meters. The greatest efficiency was obtained at a height of 3.1 meters with an ILK arrangement of 2.618%, while with the same height
