Dilution Solutions Micro-Doser Built on the Etatron eOne MF
The Micro-Doser is an assembled injection panel built around the Etatron eOne MF 0110, a microprocessor diaphragm pump made for proportional dosing. A water meter on the panel reads flow in the main line, and the pump adds concentrate in step with it. The pump delivers up to 1 L/h, about 0.26 GPH, against as much as 10 bar (145 PSI). It runs up to 180 impulses per minute with an adjustable stroke, so the dose can sit at a fraction of a millilitre per gallon. A backlit graphic display handles the programming. The wetted path is built for concentrates, with a PVDF pump head, PTFE diaphragm, TFE/P seals and ceramic ball valves. The panel arrives plumbed on polyethylene board with the meter, check valve, pressure relief valve, injection valve, unions and a mixing chamber. Suction comes through a PVC tube with a foot filter, and separate PVC priming and polyethylene discharge tubes complete the kit. The pump accepts a 100 to 250 VAC supply at 50/60 Hz. Panels come in 3/4 in and 1.5 in line sizes, each in left-to-right or right-to-left flow. A tank is not included, so plan a container for the concentrate.
Where a Micro Dosing Pump Fits in a Fertigation Room
Super-concentrated additives are the usual job, the bottles whose label rate sits below what a typical water-powered injector meters well. It was built to run alongside the Dosatron Nutrient Delivery System, which carries the base feed while this panel adds the micro-dose. Mount the panel on a wall close to the irrigation header, with the flow arrow matching the direction water travels. That is why orientation matters, since each panel is plumbed for one flow direction across the wall. Prime the pump through the priming tube before the first run, so no air sits in the head. Keep the foot filter off the bottom of the concentrate tank, where sediment settles. The pressure relief valve protects the line if a downstream valve closes while the pump is still stroking. Flush the head and injection valve with clean water when switching products. The honest limit is volume. At about a litre an hour it is made for small, potent doses, not for base nutrients. Heavy feed belongs on a larger injector, with this panel layered on top for the expensive bottle.
Key Features
- Etatron eOne MF 0110 Pump: A microprocessor diaphragm pump doses in proportion to the water meter reading.
- 1 L/h at 10 bar: Output suits super-concentrated additives on a pressurized fertigation line.
- Adjustable Stroke: Up to 180 impulses per minute with stroke control holds very low dose rates.
- Chemical-Resistant Wetted Parts: PVDF head, PTFE diaphragm, TFE/P seals and ceramic balls handle concentrates.
- Fully Plumbed Panel: Water meter, check, relief and injection valves, unions and a mixing chamber come assembled.
- Two Sizes, Two Directions: Choose a 3/4 in or 1.5 in line size in left-to-right or right-to-left flow.
