Hydraulic Ram pump is a device which works without any external energy, and uses to pump water to a considerable height by using renewable energy of water hammer. Mechanism of ram pump cycle produces the water hammer phenomenon and managements of its energy for pumping water. Simple and inexpensive system, use of renewable energy and environmental sustainability, extended the hydraulic ram pump system in third world countries especially. The ram pump system has different component. The supply source of water including springs, rivers and natural streams, drive pipe with definite length and diameter and it has the task of transferring water from the supply source to the ram pump device, set of the ram pump consists two movable valves (impulse valve and delivery valve) and an air chamber. The delivery pipe has the task of transferring the pumping water to the tank storage. The ram pump performance is such that after doing the alternative cycle, a portion of input discharge is pumped to the delivery head.
