The Barsha Pump
The Barsha Pump is a hydro-powered wheel pump which pumps water from a river to irrigate farms.
The Barsha Pump is a water wheel propelled pump that uses the flow of rivers to pump water to irrigate farms, without the use of electricity or fuel. This product is designed to help small-holder farmers to irrigate their farms at a low energy cost. The pump can be integrated with storage systems like tanks and ponds to enable farmers to store water. This product can al be linked to water distribution systems like a sprinkler system, drip system, mister, etc. to help farmers irrigate a larger area of land.
The product is distributed through aQysta’s distributors in Africa, South America and Asia.

Small- and medium-scale farms near a flowing water source.
The Barsha Pump is built in Delft, The Netherlands. It is designed as a revolving wheel that collects water from a river or canal as its water flows. The flow of the river or canal water powers the Barsha Pump, enabling it to collect water from the river or canal and sending it to the farm or water storage system for irrigation.
The exact number is unknown. However, aQysta estimates that to date, the Barsha Pump has served about 5000 farmers around the world in countries such as Nepal, Indonesia, Spain, Turkey, and Zambia.

The Barsha Pump is a water pump designed to operate without fuel or electricity. The pump can be used in rivers, streams, and canals. Barsha Pump is available in two different sizes: the narrow and the wide sizes. The dimensions of the narrow pump are 144 x 179 x 150 cm and the dimensions of the wide pump are 164 x 179 x 150 cm. The weight of the narrow pump is 75 kg and that of the wide pump is 80 kg.
The pump consists of spirals where the air is compressed between water columns resulting in air pressure that lifts the water. The pump can lift water to a height of up to 20 m or pump to a distance of 1 km, while reaching up to 40,000 liters of water per day, depending on the flow velocity of the water. Since no fuel or electricity is required for its operation, the pump does not emit polluting greenhouse gases.
In order to pump water from the water source, the pump must be connected to an HDPE pipe with a diameter of 40 mm and the length needed for the distribution of the water pumped.
The Barsha pump has a patented modular structure that allows water to be scooped up and pumped. The design consists of a spiral pump that is formed by a tube wrapped around a horizontal axis as can be seen in the image. One end of the tube is open and once per revolution, it is submerged underwater, filling partially the spiral. In each revolution, the air inside the spiral is compressed building up the pressure to pump the water outwards on the other end.
The product is said to require little maintenance. An assembly manual is provided with each pump, pre-assembly and installation are offered by the manufacturer for an additional price. The maintenance of the pump can be performed by untrained individuals.
HDPE pipe with a diameter of 40 mm, rotary coupling seal, pillow block bearing.
The pump is designed to result in zero pollution, be simple to maintain, and require zero fuel and electricity to operate.
Performance parameters including depth required, flow rate required, width required, maximum height, and distance have been vetted by researchers at the Technical University of Delft in collaboration with aQysta.Interview with representative in 2020
