Jomo Kenyatta University of Agriculture Technology, also known as JKUAT, have just launched the first ever water pump that has the ability to operate even without diesel or electricity. They branded it as the hydraulic ram pump, or simply the “hydram pump.”
Essentially, this new product is designed and manufactured using materials that are available locally. This is according to Richard Njihia, the renewable energy expert and lecturer for JKUAT. The unit, particularly, operates entirely on sound mechanical principles and does not need any source of energy or fuel to run aside from the flow of water.
“The technology is unique because it is a one-of-its-kind machine where water is being lifted without any fuel or energy. That is where hydram pump stands out when compared to other technologies,” Njihia said.
To be exact, the latest pump is a time-tested innovation that uses the energy of falling water to lift the liquid to higher heights. This, then, enables the hydram to be perfectly suitable for pumping water from a spring or stream for domestic purposes and other farm activities done on the uphill.
As Njihia explained, “the power of the pump relies on the height of the falling water. For instance, if the fall is one metre in depth, the pump can push water from the base to a height of eight metres.”
He also shared that the equipment incorporates alternating valves that let it perform continuous inflow and outflow of water. Given this, operators can expect that it can run for 24 hours straight. “Hydrams range in size, with the smallest pushing 5000 litres per day while others manage up to 20,000 litres over the same period. The cost ranges from Sh60,000 to Sh120,000,” he even noted.
JKUAT is a public university that is situated in Juja in Kenya. Their latest technology, the hyrdam, is specially designed for farmers who are looking for an alternative to diesel or electricity water pump versions.
