Dosatron D8RE5VF Standard 1–5% Water Powered Dosing Pump

The Dosatron D8 Series is a high-flow, water-powered proportional dosing pump designed to inject liquid concentrate directly into a water line. It is suitable for fertigation, irrigation, water treatment, industrial dosing and chemical injection applications where proportional dosing is required.

No. The Dosatron D8 operates using water pressure and flow as the power source. As water passes through the unit, it activates the hydraulic motor piston, draws concentrate from the container and injects it proportionally into the water line.

The D8 Series operates from 500 L/h to 8 m³/h, which is approximately 2.2 US fl oz/min to 40 US GPM.

The operating pressure range is 0.15 to 8 bar, or approximately 2 to 110 PSI.

The D8 Series includes several dosing ranges depending on the model. The D8IL3000 doses from 0.03% to 0.125%, the D8IL2 doses from 0.2% to 2%, and the D8IL5 doses from 1% to 5%. This covers ratios from 1:3000 through to 1:20.

The Dosatron D8 uses 1½" male BSP or NPT connections, listed as Ø 40 x 49mm.

The package includes 1 Dosatron unit, 1 wall mounting bracket, 1 suction tube for concentrated additive, 1 strainer, and 1 owner’s manual.

The maximum suction height is 4 metres / 13 feet. The suction tube should be fitted with the strainer and weight, then placed into the solution to be injected.

Dosatron recommends installing a filter upstream of the unit, especially when using bore water, dam water or water containing particles. The manual gives an example of 300 mesh / 60 micron, depending on water quality, and notes that filtration is required for warranty validity.

The injection area should be rinsed after use by drawing clean water through the suction tube. Routine inspection is recommended once per year, with maintenance by an approved Dosatron distributor when required.
