Irrigation

Known for their ability to be installed in any type of catchment at low cost and reducing environmental damage as much as possible, HIGRA equipment can be used for any type of irrigation. Present throughout the country, whether for flood irrigation (e.g. rice), center pivot sprinkler irrigation (e.g. sugar cane, corn, soybeans), self-propelled irrigation (e.g. oranges) or drip irrigation (e.g. oranges, sugar cane, vegetables). Among the highlights is the Semiaxial Pump. Launched in 2012, it combines high technology and higher hydro-energy yields compared to those currently used in agriculture. “The Semiaxial has come to increase the range of configurations offered to customers and has joined the Radial, Mixed and Axial rotor pumps,” say the directors of HIGRA.
