Manual Pump Fig. 1

Our “Jarro” pump is a hydraulic pump that moves liquid from one place to another. The manual water pump is a piece that can be manipulated with just one hand, to facilitate its use and the correct and safe extraction of the substance or liquid contained. To extract, it is enough to apply the minimum effort necessary to create a pressure inside the pump cylinder by operating the lever and extract the necessary amount of product through the pump mouth that has the cylinder. Its main advantage is that it does not depend on an electrical network to carry out its work, so in the event of a lack of current or supply failure it will continue to provide the service with full guarantees. Its applications are very diverse: in homes where access to the current or water is restricted or difficult (wells), to remove water from a flooded cavity, perform irrigation, emptying ponds or the domestic supply itself, without forgetting the simple decorative use since it is a piece of careful aesthetics. The hand pump extracts water by pumping it from a lower level to the surface using human power. It is based on mechanical energy, so that it has a piston that goes up and down when pumping, creating a suction effect inside the cylinder that allows the liquid to enter inside, creating a continuous current with the repetition of the motion. Its fix in case of breakage is easy, and it is possible for a user with basic mechanical knowledge to disassemble and repair it since it lacks complex components.
