The Barsha Pump

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 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.
