<br/><br/> BABAAN JOSE MARLON CORTEZ. Don Severino Agricultural College, Indang, Cavite, April l1992."DEVELOPMENT CONSTRUCTION AND TESTING OF HYDRAULIC RAM PUMP n Adviser: Eng r. Cesar C. Carriaga <br/><br/>		The study "Development, Construction and Testing of Hydraulic Ram Pump K was conducted at the Don Severino AgriculturaI College, Indang,Cavite from December 1991 to March 1992. It specifically aimed to develop and construct a low-cost hydraulic ram pump which will suit the rural conditions.<br/>           	The hydraulic ram pump has three components namely the impulse valve, the check valve, and the air chamber. The impulse valve and the check valves are the two moving parts which control the operation. The air chamber provides the pressure necessary to I if t water to higher elevation. The hydraulic ram operates at a minimum fall  30.49 cm. (1 feet) and tested up to maximum falI 152.44 cm. (5 feet). The maximum delivery was obtained at 152. 44 cm. (5feet) fall l with 50. 33 1 i tar 5 per minute lift of 152.44 (5 feet). On the other hand, the lowest delivery of 2. 15 liters per minute was observed when its fall l was 30.49 cm. (1 foot) with a lift of 91.46 cm, (3feet). The highest and lowest efficiencies were observed at 152.44 cm. (5 feet) fall with 152.44 cm. ((5feet) lift and 30.49 cm. ((1foot) fall l with 91.46 cm. (3 feet) lift, with values of 64-81% and 2.4% respectively.The efficiency decreases as the I if t increases; and increases as the fall increases. I t was also observed that the I if t increases as the fall increases. The number of pumping action of the impulse valve determinesthe amount of water delivered. The developed hydraulic ram was more adaptable in operating at I owe r falI but has a lower overall efficiency than the commercial hydraulic ram.The total cost of the developed hydraulic ram was PI, 329. 00. I t was constructed from readily available. Materials low cost of developed hydraulic ram implies that it is more economical as compared to commercial hydraulic ram, and centrifugal pumps. Also, it is easier to maintain, operate and replace parts because parts are readily available with I east coast. Thus, we can say that the developed hydraulic ram was adaptable to rural areas where Chere is sufficient source of flowing water.<br/>
