BERMAD Solutions for Mechanized Irrigation

BERMAD Solutions for Mechanized Irrigation Balancing & Managing Systems with Irrigation Machines Mechanized irrigation was developed during the 1940’s to include Center Pivot, Lateral Move and Linear Move irrigation machines in cultivated fields using minimum labor and infrastructures. These machines often need to move over diverse terrain types, including sloped areas and muddy fields. They represent relatively large irrigation units, both from a hydraulic and irrigation perspective. 6” x 200m; mile line = 30Ha; 75 acre = 100m³/h; 450gpm 8” x 400m; ¼ mile line = 50Ha; 125 acre = 170m³/h; 750gpm These factors, together with the need to irrigate different crops growing in variable soil types, make the water supply and distribution management challenging . BERMAD Leads the Way in Answering these Challenges With its proven track record and global presence, BERMAD offers ongoing support in integrated irrigation solutions required for mechanized irrigation; providing protected, efficient, and reliable hydraulic systems for long-term, accurate, and uniform irrigation control.

Main Water Supply System, with Multiple Consumers and Pivots Pressure and Flow Control Achieving continuous, stable, reliable, and efficient water supply in areas with elevation differences is a known requirement. However, effective pressure and flow control can also be challenging in relatively flat planes for the following reasons:   Accumulating distance of irrigation units from the pressure source   Differences of unit sizes in terms of flow and required operational pressure   Variety of irrigation methods (e.g. flood, drip, sprinklers, pivots) and of crops with different schedules and...

Inlet of Center Pivot As Center Pivots serve large irrigation units, they require that all standard monitoring and control solutions facilitate hydraulic secured operations with precise and uniform irrigation. The following challenges also arise because they act as moving distribution lines:   The line gets empty whenever Pivots main valve shuts and fills up when it opens.   The line slope may vary from uphill to downhill during irrigation.   They comprise multiple joints and carry tons of water, and the line is driven 6-9m; 20-30ft above ground. This creates mechanical and hydraulic...

End of Center Pivot Located furthest from the controller, the end tower of a center pivot represents the peak of required performance: Fastest motion, highest nozzle flow, lowest pressure and flow velocity (sedimentation), and various plot borders (end guns & corners). End-Gun Valves – “Squaring the Circle” Center Pivots rarely irrigate round fields. This leaves the corners out of the irrigation circle. A common and effective solution for adding up to 30% to the irrigated area at the corners is installing a sprinkler at the end of the Center Pivot (End-Gun), and activating it at the right...

End of Center Pivot Regularly Flushing Sand & Dirt The relatively slower flow velocity at the end of the Center Pivot results in sand and dirt sedimentation that accumulates towards the water source. This might clog more and more sprinklers while also adding extra weight over the end tower and span. The installation of a flushing valve at the end of theline, allows for regular flush out to help prevent this sedimentation from accumulating. BERMAD offers a range of automatic fail safe closed flush valves with a selfcontained hydraulic or battery-powered timer control (with BT setting) to...
