|PAT Name=Hydraulic RAM Pumps
|PAT Picture=Hydraulic Ram Pumps.jpg
|PAT Type RE=Renewable Energy
|PAT Description=A hydraulic ram is a cyclic water pump powered by hydropower. Hydraulic RAM pumps use the energy in larger volumes of flowing water energy for lifting smaller volumes of water. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The hydraulic ram is viable in all areas where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. Hydraulic Rams require no outside source of power. This is a well established technology already in use for hundreds of years. 

The AIDFI RAM Pump is a simplified version capable of local manufacture, installation, and maintenance. 

The limitation of hydraulic ram pumps are that they require reliable surface water flows and are therefore not always a viable water lifting solution.

|PAT Manufacturers=AID Foundation Inc., Green and Carter
|PAT Economics=Hydraulic RAM pumps are very economical and they are reliable. Modern designs including the AIDFI will operate for years with little or no maintenance requirements or additional energy inputs. They, therefore, offer an excellent return on their economic and resource investment.
|PAT Technology Development Level=RAM Pumps are excellent examples of slow tech, they are highly developed technologies with basic resources, maintenance, construction, and operational requirements. They have very few parts and are reliable. RAM Pumps are well developed solutions for agricultural irrigation or community source water.
|PAT Maintenance=Hydraulic Ram Pumps have little expected maintenance requirements. The maintenance can be managed by community members using locally sourced materials.
|PAT Infrastructure=The required infrastructure for deployment of Hydraulic RAM Pumps already exists in most parts of the world. Further deployment is depending on training and education as well as required investments.
|PAT Required Resources Manufacture=Steel, PVC, Rubber, HDPE
|PAT Required Resources Operation=None
|PAT Deployment Level=AIDFI and Green and Carter have many installations through out the world. AIDFI and Green Empowerment are successfully transferred their Hydraulic RAM pump techonolgies to Nepal, Afghanistan, and Columbia.
|PAT Deployment Capability=Further deployment is possible with funding for viable site location. Great potential for deployment of this technology exists in developing as well as industrialized countries. RAM Pumps are an excellent solution wherever reliable surface water flows exist.
|PAT Requirements for Deployment=Some technical expertise in site location, development, and installation is needed.
|PAT Relevance Autonomy=The ADFI RAM pump is energy and service independent- but requires supporting technology for manufacture and distribution. Once installed they offer autonomy and food security for small farm irrigation needs.
|PAT Environment Impacts=There are no emissions during operation. The only emissions are during manufacture and distribution.
|PAT Bio-Cybernetic=RAM Pumps conform with the Bio Cybernetic Rules.
