The basic idea behind a ram pump is simple. The pump uses the momentum of a relatively large amount of moving water to pump a relatively small amount of water uphill. The pump has a valve that allows water to flow through this pipe and build up speed. Once the water reaches its maximum speed, this valve slams shut.
The volume of water able to be delivered is dependent on the available fall and the required head, our ram pumps will work on sites with as little as 500mm of fall and are able to deliver water up to ten times the head of the available fall. If required, our pumps can be installed in series to achieve a greater head.

= 14400 LITRES PER DAY, EVERYDAY, WITH OUR SMALLEST PUMP
Consider that a spring or river providing a flow of 100lt per minute can, through an Evergreen Gravity Pump, supply 20lt per minute at a head of over 80m up to a distance of 1km away with our smallest pump.
10lt x 60minutes x 24hrs gives you 14400 litres per day, everyday. That is sufficient to provide water for the basic needs of 360 people per day.
- Simplicity of design and reliability of build guarantee minimal maintenance requirements
- Monitored irrigation in rural areas will enable small scale farmers to improve their crop yields
- Depending on the water source, filtration systems can be put in place to provide drinking water
- Farming methods can be taught in the rural areas by our team.
