<p>The present invention provides a two cylinder bullock-driven reciprocating piston pump assembly comprising of two-cylinder barrel sub-assemblies, with piston valves and check valves which function in an order opposite to each other (staggered by 180 degrees); pulley housing and connecting water chamber subassembly; and bevel-gear sub-assembly, which is driven by the farm animal, preferably bullock. The present invention employs a mechanism where the piston assembly in two cylinders is pulled by steel wire ropes instead of connecting rods. The connecting rods in conventional pumps are subjected to pull and push, therefore may buckle when used in deep bore wells. Thus, by using steel wire ropes, the two-cylinder animal-driven reciprocating piston pump may be used for deep bore-wells, while reducing the cost of manufacturing. The present invention ensures continuous discharge of water, as the check valves and the piston valves in both the cylinders operate in dispositions opposite to each other.</p> |
