Dosatron SYSD15RE05VF Hobby Cultivator 0.5% Water Powered Dosing Pump System

The Dosatron D15 Series is a water-powered dosing pump used to inject liquid nutrients, fertilisers or additives into a water line. It is commonly used for hobby growing, fertigation, irrigation and direct nutrient dosing systems.

No. The D15 operates using water flow and pressure. As water passes through the unit, it draws concentrate through the suction hose and injects it proportionally into the water line.

The D15 system shown in the guide operates from 0.5 to 5 GPM, which is approximately 1.9 to 18.9 L/min.

The operating pressure range is 35 to 87 PSI, which is approximately 2.4 to 6 bar.

The D15RE05 model shown in the guide has an injection rate of 0.5 to 5 mL/L, or 1.875 to 18.75 mL per gallon.

A 3/4" filter, 200 mesh / 80 micron, is recommended before the system to help protect the injector from debris and maintain reliable operation.

Yes. Multiple D15 units can be installed together in a straight horizontal line, U-shape or serpentine configuration. The important requirement is that the water flow direction remains consistent through all units and follows the flow arrow on each injector.

Yes. The D15 can be used for direct injection, where nutrients are injected into the water line and sent directly to plants, or for a batch tank method, where the mixed solution is sent into a holding tank before being pumped to the plants.

The unit should be mounted securely using studs, suitable anchors or unistrut. The guide also notes that Dosatron units should be positioned above the stock solution containers to help prevent siphoning.

To adjust the dosing rate, loosen the lock nut, turn the injection sleeve clockwise or counter-clockwise to the desired setting, then re-tighten the lock nut. After priming, the guide recommends testing EC and pH and making small adjustments if required.
