Abstract

The water pump is an equipment capable of draining water from a river for domestic use and watering from a short geometrical unevenness using only the cinetic energy of a water hammer, reaching determined gauged heights, being an excelente alternative for use in locations of difficult access or where electric energy is not available for the use of conventional centrifugal pumps. This work was made with the objective of verifying the efficiency and productivity of a water pump built with 32 mm diameter PVC pipes. For the analysis, field trials were performed, where three different uneven geometries between the supply tank and the pump were tested, as well as the different flow rates. The water flow was approximately 120 L/h (with 100% opened registry), and can vary according to necessity, changing the diameter of the pump’s construction tubes and the hammer pulses. The average flow rate for each geometric unevenness (GU) between the power supply and the pump were of 102,4 L/h for GU = 2.00 m with 159,33 pulses/min in average; 123 L/h for GU = 2.90 m with 126 pulses/min in average; and 123 L/H for GU = 3.50 m with an average of 124.5 pulses/min. It was concluded that the pump is efficient and practical, with low cost and easy installation; without the need of constant maintenances and is adequate for long distance installation in rough terrain, being a great alternative for installation in the cited locations.
