Journal of Science and Technology 4:51-59(2018) Surigao State College of Technology, Surigao City, Philippines Enhancing Pumping Capacity Through Pressure-Gravitational Forces Combination Gregorio Z. Gamboa Jr.,* Ricky T. Osorio, and Richard A. Badiola Surigao State College of Technology, Main Campus, Surigao City, Philippines Abstract This study aimed to determine the pumping capacity of ram pump. Secondary data were used in determining the performance of the fabricated ramp pump compared with other brands. Descriptive method was used and hydraulic analysis was conducted. Findings revealed that the computed capacity of the constructed ram pump is 11,404.8 liters per day using the following variables; Fall – 1.8 meters; Rate of Flow or Q – 90 liters/minute; Lift – 18 meters; Efficiency – 0.66 theoretical value. The efficiency of the constructed ram pump is 32.96% and do not fall below compared to the performance of the ten leading ram pumps available in the market. Based on the findings of the study, the constructed ram pump is comparable to the commercially available ram pump in terms of performance and efficiency.

The absence of it means paralysis of human’s activity; its inadequate supply means a challenge. For the residents of Barangay Campawog, San Fernando, Cebu where farming is the main source of living, water supply is beyond necessity as the water source in the area is located several feet below a treacherous ravine. Thus, this study claims that the combination of pressure-gravitational forces enhances pumping capacity of water using ram pump, in particular to the water source under a treacherous terrain. It has been established that hydraulic ram pumps are ecologically friendly devices using a renewable energy supply to pump water for domestic or agricultural use (Young, 1995). Hence, in far-flung communities, renewable energy generation is most appropriate in response to people’s present needs for they require low initial and maintenance cost, with proven technology (Jain Patel, 2014). Pressure forces then are considerable in the development of water systems technology as they have some unique qualities with comparable potentials to gravitational or mechanical forces. The rising technology at present drives humans to continuously improve the way of life. Possible solutions to challenges at hand are within reach also because of human’s creativity and innovativeness. Hence, the current situation of Barangay Campawog can be addressed by providing an adequate water supply for their household and farm use. This can be done using a water pump to bring water up. The use of ram pump is introduced to cater the pressing need for adequate water supply of the concerned residents. This is deemed an economical practice since it only uses the water hammer effect to pump water to a higher elevation. It can operate the whole day, seven days a week without interruption. It is easy to maintain, environmentally friendly, safe, no gas emission, and no heat generated during operation. Thus, this study aims to determine the performance of ramp pump and compare it with the commercially available in the market. *correspondence: greggy3659@yahoo.com
