Five years of research and testing have culminated in its D5000 flow-regulated drip lineMORE usually associated with high horsepower tractors and headers, machinery giant John Deere has selected Australia to be the first country to commercially manufacture and supply a drip line product with appeal to our irrigation industry.
Five years of research and testing have culminated in its D5000 flow-regulated drip line being sourced from John Deere Water’s Melbourne production facility.
“The worldwide launch of a drip line product in this country reflects John Deere Water’s commitment to the Australian agricultural sector as growers strive for increased irrigation efficiency improvements,” managing director, John Deere Water Australia/New Zealand, Peter Wanckel said.
Available in various configurations to meet the needs of individual growers, Deere’s D5000 product is available in diameters up to 27mm. This is said to make the drip line ideal for long run lengths often required in vineyard, cotton and almond enterprises.
Developed with a pressure regulating capability of 50 – 350kPa, Deere says the increased pressure envelope is especially useful over undulating terrain where pressures at the bottom of slopes can easily build to more than 300kPa.
An interesting aspect of Deere’s D5000 Drip Line technology lies in its resistance to clogging – even after foreign particles were deliberately added into the water source.
Specifically designed for Australian conditions and applications, its engineers have come up with a dripper with three large inbuilt parallel inlets, also a labyrinth with a large cross sectional area.
The combination of these two features is the key to reducing clogging, principally by creating more area for foreign particles to flow.
And an additional self-cleaning function within the dripper looks to be an added bonus.
Deere says as dirt particles accumulate in the dripper, pressure also builds up against the top layer of the diaphragm.
This pressure imbalance causes the diaphragm to open to release the particles, ready for the diaphragm to resume normal flow regulation once the dirt particles have been freed from the system.
The upshot leaves Deere claiming its D5000 product is the most clog resistant mainstream drip line on the market.
