With a continuous flow of water a hydram operates continuously with no external energy source. The delivery head of hydraulic ram ranged from 7.03 m to 35.16 m for a pressure range of 0.703 to 3.52 kg/cm 2. Hydraulic ram has a maximum efficiency of D’ Aubussion’s efficiency and Rankine’s efficiency 56.26% and 52.77% and a minimum efficiency of D’ Aubussion’s efficiency and Rankine’s efficiency of 48.56% and 42.45%. characteristic curves of hydraulic ram working under conditions of constant waste valve lift, constant supply head and varying delivery head. With increase of delivery head the number of impulse frequency beats increases.

The pump has the following characteristics flow, drive that is how much water is available to run the pump; drive head is the drop from the water level in the drive tank to the pump; delivery flow is the amount of water flowing into the delivery tank while the delivery head is the height from the pump up to the delivery tank. The normal operation range of this pump is 0.5 to10 litres/minute. The ram pumps are durable and either made from iron casting or welded steel pipe. The readily available local materials have been used to build the pump. No electricity or any power fuel is required to run the pump, therefore, it is less expensive to own and operate. The hydraulic Ram pump is a complete automatic device that uses the energy in the flowing water such as spring, stream or river to pump part of the water to a height above that of the source. With a continuous flow of water a hydram operates continuously with no external energy source. Working Principle Hydraulic ram pump works on the principle of water hammering action. The water is caught by the spring catchment (or the stream catchment) and driven to the header tank by the feed pipe. The spring or stream catchment is the first barrier to prevent organic matters to enter in the system and to reduce the efficiency of the system. The header tank allows a continuous flow to the drive pipe and the pump and it the last barer to prevent sediments to enter in the pump. The drive pipe is made from galvanized iron (G.I.). It has to support the water hammer effect which is running continuously. The drive pipe is designed to conduct water as fast as possible to the pump and it must be straight. The Hydram is the most critical infrastructure of the system. The Hydram is attached to the pump basement. It has to absorb the shocks of the water hammer effect. The pump basement has to be carefully design because it is subject to the fatigue of the water hammer effect and is very difficult to maintain without stopping the pump from running. The delivery pipe conducts the water from the pump to the storage tank. The storage tank is used to hold water before it is delivered to communities.
