Dosatron D9GL5VF Greenline 1–5% Water Powered Dosing Pump

The Dosatron D9 Series is a water-powered proportional dosing pump designed to inject liquid concentrate directly into a water line. It is suitable for larger irrigation, fertigation, water treatment, livestock, and chemical dosing applications where accurate proportional dosing is required.

No. The D9 operates using water pressure as the only power source. As water flows through the unit, it draws in the concentrate, doses it to the selected percentage, mixes it with the water, and sends the solution downstream.

The D9 Series operates from 500 L/h to 9 m³/h, which is approximately 2.2 to 40 US GPM.

The operating pressure depends on the selected model. The D9WL3000 and D9WL2 operate from 0.3 to 8 bar, while the D9WL3000IE and D9WL5 operate from 0.5 to 8 bar.

The D9 Series includes multiple dosing ranges depending on the model. The D9WL3000 doses from 0.03% to 0.2%, the D9WL2 doses from 0.2% to 2%, and the D9WL5 doses from 1% to 5%. This covers ratios from 1:3000 through to 1:20.

The D9 uses 1½" male BSP or NPT connections, listed as Ø40 x 49mm. It can be connected using suitable 40mm internal diameter flexible pipe and swivel fittings.

The package includes 1 Dosatron unit, 1 mounting bracket, 1 suction hose for concentrate, 1 strainer, and 1 quick start guide. The IE models also include the external injection kit.

The maximum suction height is 4 metres / 13 feet. The suction hose should be fitted with the strainer and ballast, and the strainer should sit around 10cm above the bottom of the solution tank to avoid drawing in sediment.

An upstream filter is recommended and required for warranty validity. Dosatron recommends filtration such as 130 micron / 120 mesh or finer, depending on water quality. This is especially important when using bore water, well water, dam water or surface water.

The Dosatron should be flushed with clean water after use, especially when changing chemicals. Annual maintenance is recommended, including replacing the dosing seals and the additive suction hose at least once per year.
