The project aimed to develop, evaluate, and promote a hydraulic ram pump for small irrigation systems to support high-value crop production in upland areas. A functional testing rig was designed and constructed based on a comprehensive literature review. The testing rig consisted of a frame, water supply tank, water header tank, drive pipe, hydraulic ram pump assembly, and hydraulic ram pump support structure. It was successfully utilized to assess the performance of RERC-developed hydraulic ram pump prototype using a three-factor factorial experiment in a completely randomized design (CRD). The factors tested were drive pipe angle (5°, 10°, and 15°), waste valve angle (34°, 46°, and 59°), and delivery pipe diameter (1”,3/4”, and 1⁄2”). Results revealed that these factors significantly influenced water discharge (Q, li/min), discharge height (h, m), and air chamber pressure (P, kPa). The parameter combination that gave the highest water discharge of 15.44li/min and a delivery height of 6.38m was at 10° drive pipe angle, 34° waste valve angle, and 1” delivery pipe diameter. These findings demonstrated the effectiveness of the testing rig for evaluating any ram pump prototypes and highlighted the RERC-developed ram pump is potential for small-scale irrigation in off-grid areas. Following the technical evaluation, RERC designed and implemented a demonstration farm featuring a drip irrigation system powered by the hydraulic ram pump to support high-value crop production. Additionally, a focus group discussion with upland farmers in Baybay City was conducted to explain the functionality and benefits of ram pumps with positive feedback among upland farmers. Technology was further promoted during VSU founding anniversary celebrations, attracting interest from potential clients seeking to adopt the innovation.
