ANALISA UNJUK KERJA POMPA HIDRAM DENGAN PENAMBAHAN TABUNG PEMBAGI TEKAN
Water is source of life for human being, plant and animal. One of effort to complete of
water required is by using hydram pump. Hydram pump (Hydraulic ram pump) is a pump that work
without required energy from outside for its activated, but work done by exploiting force from source
of water. This research purposes to know influence of pressure divisor to water hammer effect and
to know influence of pressure divisor to efficiency of hydram pump. This research used hydram
pump by the specification of air tube it’s 60 cm height and 3 inches diameter. Elevation of plunge
from pump body is 2 meters and elevation of output is 4 meters. Height of air tube at pressure
divisor that is 20 cm, 30 cm, 40 cm and 50 cm and elevation of variaty pressure divisor from body
pump is 2 meters, 2,5 meters and 3 meters. The method used in this research is experiment
method. The quantitative data made in table and displayed graphically. The results show that the
highest of maximum head at 2 meters elevation of pressure divisor from pump body and 20 cm
high of tube, while lowest of maximum head at 3 meters elevation of pressure divisor from pump
body and 50 cm high of tube. The best efficiency at 2 meters elevation of pressure divisor from
pump body and 20 cm high of tube that is 31,62%, while the lowest efficiency at hydram pump
installation without of pressure divisor that is only 26,62%.
Keywords: Hydram pump, Pressure divisor, Efficiency.
