What is a Ram Pump?

The AIDFI Ram Pump is a perfected model of a forgotten technology: the Hydraulic Ram Pump. A Ram is a device which uses the energy contained in falling water to lift a portion of this water to a higher elevation. The AIDFI model is a crossbreed (best of both) of expensive-heavy-duty-cast models commercially available and inferior-low-cost models developed by Appropriate Technology Groups and Universities. The AIDFI Ram Pump compared to other ram pumps uses a steel to steel impulse valve mechanism, making regular and costly replacement of gaskets unnecessary. This unique mechanism makes the model also very efficient. The highest elevation we have reached so far in an actual setting has been 240 meters, and we're sure we can go beyond that. The pumps are made one by one to order and are already available in ten different sizes, with each pump having a specific flow range making it a perfect solution for either drinking or irrigation projects.

How it works
DEVELOPMENT OF THE AIDFI MODEL

AIDFI has been in ram pumps since the late 80s, and over the course of that time, has perfected a model based on locally available parts and spare parts, such as a common door hinge or an old car tyre. It is a combination of the commercial and do-it-yourself ram pumps available: high technical performance but low cost. The pump itself is fabricated in a our shop but once it is installed, it can be operated, maintained and repaired by locally trained technicians.
