| dc.description.abstract | Indonesian including areas that have abundant water supply so that from this energy can be utilized in
order to diversify energy. One of the tools that utilize water energy is a sling pump. The equipment
consists of propellers, to twist, coil pipe and pipe delivery. Sling pump can be applied as irrigation,
fish ponds, ponds and fields. Until now sling pump has not been used by many people because it is still
in development. For that need to be made sling pump model that will be applied in a river. Model can
be used to study the performance of the experimental study of cone sling pump with pipe diameter
variations, variations in the number of inlet pipe, variations in the number of coils of pipe, variations
in the height of delivery. Model making sling pump preceded by a planning which includes a survey of
the river flow velocity, determining the rotation speed, dimensions sling pump, the selection of
propellers, shafts, bearings, rotary seals, tools and measuring instruments vest. After the sling pump
components are assembled, they were tried in the river to check in case of leakage in the rotary seal. If
the sling pump has worked well, done taking the data in the form of water discharge and water
pressure output. The materials used in making the framework sling pump is a solid aluminum pipe
with a diameter of 8 mm, size of frame length 62.7 cm, diameter 47 cm large and small diameter of
13.82 cm. Models made slings pump has been operating well in the rivers. Based on experiments
performed, the result is an average discharge of 5.915 liters / min, the hydraulic efficiency of 75.83%
and 9% efficiency sling pump.
