Mixtron hydraulic dosing pumps are installed in the water line and inject fertiliser or nutrients in proportion to the flow passing through them. This guide brings together the application video, available models and the details to confirm before buying.
Proportional dosing without electricity
- Runs on water pressure and flow, with no external electrical supply.
- Keeps dosing proportional to water volume within the pump's operating limits.
- Promotes a uniform water-and-nutrient mix and helps reduce overdosing and waste.
Why it suits fertigation
- Runs on water pressure and flow, with no external electrical supply.
- Keeps dosing proportional to water volume within the pump's operating limits.
- Promotes a uniform water-and-nutrient mix and helps reduce overdosing and waste.
- Can be integrated into greenhouses, nurseries, orchards, farms and hydroponic systems.
How to choose the right model
Confirm these five installation details before choosing a pump:
- Minimum, normal and maximum irrigation-line flow.
- Required injection percentage for the fertiliser or nutrient.
- Water pressure available during operation.
- Chemical compatibility with the pump seals and materials.
- Installation layout, filtration, non-return protection and required accessories.
Two ranges for two dosing concentrations
P003 series · 0.03–0.3%
For low-concentration injection. Four flow capacities available from Lubricalia.

| MX.300.P003 | 3,000 l/h | 0.03–0.3% | View product |
P022 series · 0.2–2%
For dosing requirements up to 2%. Four flow capacities available.
| Model | Maximum flow | Dosing range | |
|---|---|---|---|
| MX.075.P022 | 750 l/h | 0.2–2% | View product |
| MX.150.P022 | 1,500 l/h | 0.2–2% | View product |

Featured P003 models
Choose by line flow; if demand varies widely, size the unit using the real minimum and maximum values.
Documented applications
The fertigation document includes installations in orchid plantations, cotton fields, fruit farms, greenhouses and banana crops in several countries. The operating principle is the same: adding concentrate in proportion to irrigation water.
Frequently asked questions
Does a Mixtron dosing pump need electricity?
No. The hydraulic models in this guide use water pressure and flow to drive dosing, so they require no external electrical supply.
What information is needed to select a model?
Minimum and maximum flow, dosing percentage, water pressure, chemical product and installation layout. We can then check the range, seals and accessories.
What is the difference between P003 and P022?
The P003 series operates from 0.03 to 0.3%, while P022 operates from 0.2 to 2%. Both are available with maximum flows of 750, 1,500, 2,500 and 3,000 l/h.
Does the proportion remain constant when water flow changes?
Yes, provided flow and pressure remain within the model's operating limits. The pump adjusts injection proportionally to the volume of water passing through it.
We can size the dosing pump with you
Send us the flow, pressure and target concentration. Lubricalia will review the suitable model and accessories with you before ordering.
