Ram Pump design
Published on by Ramchand Jailal BSc; MSc; PMP, Executive Director, IPI at Guyana Water Incorporated
I am very interested in the design of hydraulic ram pumps.
A hydraulic ram pump is a cyclic water pump powered by hydropower and therefore requires no external power source.
Can someone please share design details for ram pumps or tell me when I can find them?

The hydraulic Ram pump or hydram 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.
A hydram is a structurally simple unit consisting of two moving parts.
These are the
- impulse valve (or waste valve) and
- the delivery (check) valve.
The unit also consists of an air chamber and an air valve. The operation of a hydram is intermittent due to the cyclic opening and cloning of the waste and delivery values. The closure of the waste valve creates a high pressure rise in the drive pipe. An air chamber is required to transform the high intermittent pumped flows into a continuous stream of flow. The air valves allow air into the hydram to replace the air absorbed by the water due to the high pressure and mixing in the air chamber.
