Competitive Landscape

Direct competitors include Futurepump SF1 Solar Pump.

Manufacturing/Building Method

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.

User Provision Model

Users can acquire the Barsha Pump through aQysta's distributors in Africa, South America, and Asia. The company also partners with other organizations to make the product available at reasonable costs. Users can also contact the manufacturer directly to buy the Barsha pump.

Distributions to Date Status

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.

Design Specifications

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. For the pump to work properly, the flow rate of the river or stream or canal should be at least 0.8 m/s. The river should have a minimum depth of 20-50 cm and a minimum width of 150 cm.

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 was tested by Technical University of Delft in collaboration with aQysta. Interview with representative in 2020
