Design of a 1½ " Ram Pump and Testing the Effect of Variation in The Launch Pipe Slope Angle Against the Pump Performance

Areas with higher land surface than water sources will have difficulty in obtaining a continuous water supply. One effort to meet water needs, especially in locations that are higher in position than springs, is to use a water pump. The types of pumps commonly used today are water pumps powered by electric motors or combustion engines with fuel oil (diesel or gasoline). For urban areas the need for fuel oil is not too much of a problem. Meanwhile, in rural or remote areas the existence of Fuel oil is very stepped, even if there is a very expensive price. Ram pumps can be one solution, the problem is that rivers or water sources that have high waterfalls cannot be found near the settlement area, it can only be found in remote areas far from settlements. For this reason, the purpose of this research is to design and build a ram pump with the ideal slope angle of the Launch pipe which can improve the performance of the ram pump. Conducted research using a 1½-inch hydram pump at a 1.2m fall height by varying the slope angle of the launch pipe and the Launch pipe diameter, obtained the best pump performance at 11.5o angle variations and 50mm pipe diameter
