Abstract


One effort to overcome water difficulties, especially in areas with higher elevations than water sources, is to use a pump. At this time there are various types of pumps used. The type of pump that is widely used today is the pump using the power of an electric motor or diesel power. Pumps using the power of an electric or diesel motor require fuel oil so that it requires additional costs in operation.

               The purpose of the research conducted on this hydram pump is to determine the discharge obtained by four parallel hydram pumps and analyze the efficiency of the hydram pump with a variation of the diameter of the exhaust valve and suction valve 11/4 inch diameter and 1 inch. The research was conducted experimentally by flowing water from the reservoir as a water source with a height of 2.73m with an inlet pipe slope of 12.5o. The water from the reservoir is flowed to a hydram pump with a variation of the input diameter of the hydram pump pipe which is 11/4 inch 4 meters long and 11/2 inches long by 5 meters, with a pipe output diameter of 1/2 inch with a height of 8m. To find out its efficiency, we calculated pumping discharge and pump discharge discharge which will be known how efficient the pump is with variations in the diameter of the exhaust valve and 1 inch suction and 11/4 inches with inlet pipe variations.

            The results showed that the maximum yield discharge from the four parallel hydram pump was obtained at pump 1 with a suction valve diameter and 11/4 inch exhaust valve with a discharge of 0.0311 l/s and a minimum yield of 0.0067 l/s at pump 3 with diameter of 1 inch suction valve and 11/4 inch suction valve. The highest efficiency obtained from the four parallel hydram pump that is at pump 1 with a suction valve diameter and 11/4 inch exhaust valve produces an efficiency of 2.91%, and the lowest efficiency is 0.62% on pump 3 with a diameter of 1 inch suction valve and 11/4 inch exhaust valve
