Product Overview
The Dosatron D90GL05VF is an ultra high-capacity, non-electric proportional dosing pump designed for precise injection of liquid concentrates directly into high flow water lines. Powered entirely by water pressure, the unit automatically doses additives with an externally adjustable ratio from 0.1% to 0.5%, delivering accurate and consistent chemical injection without the need for electricity.
Installed directly inline with the water supply, the D90GL05VF uses a patented 1/10 flow regulator to divide flow before the proportional dosing pump injects the concentrate at the selected percentage. This intelligent flow division system stabilises performance and helps maintain accurate dosing across a wide operating range, even in demanding irrigation applications.
The D90 Green Line Series is designed for large scale agricultural and fertigation systems where very high flow capacity and dependable dosing are essential. Its mobile configuration, robust construction and simple start-up make it ideal for fruit and vegetable production, field crop cultivation and other high volume irrigation installations.

Frequently Asked Questions
What is the Dosatron D90GL used for?
The Dosatron D90GL is designed for high-flow fertigation applications, including fruit and vegetable production, field crop cultivation, and large irrigation systems. It is built for farms that need proportional chemical or fertiliser dosing at very high water flow rates.
What flow rate does the Dosatron D90GL handle?
The D90GL operates from 25 m³/h to 90 m³/h, which is approximately 110 to 400 US GPM.
What is the dosing range of the D90GL?
The D90GL has an adjustable dosing range of 0.1% to 0.5%, equal to a ratio of 1:1000 to 1:200.
Does the D90GL require electricity?
No. The D90GL is water-powered and uses the pressure and flow of the water line to operate, so no electricity is required. This makes it suitable for remote irrigation and farm applications.
What pressure range does the D90GL operate at?
The D90GL operates from 0.5 to 8 bar, or approximately 7.25 to 116 psi.
What connection size does the D90GL use?
The D90GL comes with flange connections: DN100 EN PN16 or DN 4" ASME B16.5.
What chemicals can be used with the D90GL?
The D90GL is compatible with soluble, liquid, conventional and organic fertigation products. Seal selection is important depending on the chemical being used, with VF for acidic fluids and AF for alkaline fluids.
Can the D90GL be moved around the farm?
Yes. The D90GL is promoted as a mobile high-flow dosing solution and can be moved to different irrigation areas where required.
Does the D90GL have a bypass?
Yes. The D90GL includes an integrated manual bypass. When the bypass is ON, the Dosatron operates and draws concentrate. When the bypass is OFF, clean water flows through without product being injected.
Is a filter required before the D90GL?
Yes, an upstream filter is strongly recommended, especially when using bore, dam, river or surface water. Dosatron recommends a filter around 200 to 120 mesh / 80 to 130 microns, depending on water quality, to reduce wear from particles.
What is the maximum suction height?
The maximum suction head for the concentrate suction hose is 4 metres. The suction strainer should also be kept around 10 cm above the bottom of the chemical container to avoid drawing in sediment.
How often should the D90GL be serviced?
Annual maintenance is recommended. Dosatron advises replacing the dosing assembly seals and product suction hose once per year to maintain reliable and accurate dosing.
What is included with the D90GL?
The package includes the Dosatron unit, two elbow fittings, two supply tubes, the Dosatron regulator, suction hose for concentrate, suction strainer and a quick-start guide.
