Although their factory in Matsapa is relatively new, New Dawn Engineering (NDE) has been developing appropriate technology since 1984.
The company is known for its comprehensive approach to development, design and manufacture of labour-intensive production equipment, says research and development manager Crispin Pemberton-Piggot.
As development of appropriate technologies in recent years has been rapid, NDE provides training in the design, building, maintenance, use and economics of its own products, and also in customer specified projects and programmes.
The foot-operated low lift platform pump
This pump is designed for small-holder irrigation where significant quantities of water are required to be pumped to a low head. An area of up to two acres can be irrigated. With different cylinders from 51 to 152 mm in diameter, the NDE platform pump can deliver as much as 5 cubic metres per hour to a low lift, or 350 litres to a head of 65 cubic metres. The pump can draw water from a river, sump or a shallow well.
Treadle pump
A treadle pump (pictured)is a foot-operated, single acting, double cylinder piston pump for low lift irrigation. These pumps were originally developed in Bangladesh for pulling water up to the pump level. Later they were adapted in Kenya to push water higher than the pump. NDE’s pump features 6mm thick cylinder walls and the latest patented valve design for treadle pumping. The ball bearing mounted steel pulley is retained. A wire rope option has been introduced to replace the standard polypropylene rope.
Ram pumps
NDE has designed many ram pumps. Ram pumps pump water uphill without electricity or powered engines. They simply use the water power created by a vertical fall in a river or spring over a slope of about 1 in 5.
