Horticulture & Fertigation · Australia-wide
Fertigation injectors, dosing pumps and spraying equipment for Australian horticulture — blending fertiliser, nutrients and water-soluble products into your irrigation line at a precise, repeatable ratio.
Precision Flow Solutions supplies fertigation injectors, dosing pumps and spraying equipment for Australian horticulture. Our injectors blend fertiliser, nutrients and water-soluble products into your irrigation line at a precise, repeatable ratio, so crops, blooms, turf and ornamentals get exactly what they need with less waste and lower input cost. We supply, install and service across Australia from our Northmead base in Sydney.
We work with nurseries, greenhouses and glasshouses, garden centres, turf and golf course operations, orchards and vineyards, tree farms and hydroponic growers. With one of the widest ranges of flow and injection rates available, we match the injector to your line size, water pressure and dosing requirement rather than forcing your system to fit the equipment.

Fertigation is the practice of delivering fertiliser and nutrients to plants through the irrigation system rather than applying them separately. A proportional injector sits in the water line and draws concentrate into the flow at a set ratio, so every plant on the line receives the same nutrient concentration.
Done accurately, fertigation puts nutrient exactly where the roots are, at the rate you choose, with far less run-off and labour than manual application. Done inaccurately, it wastes expensive fertiliser and produces uneven growth across a block. The difference is the injector.
A water-driven proportional injector uses the flow and pressure of your irrigation water as its only power source, with no electricity required. Water entering the unit drives an internal motor, which draws a set percentage of concentrate from your stock solution and injects it into the flow. Because the injector is driven by the water itself, the dose stays proportional even as flow rate varies, and the mixed solution is carried downstream by line pressure.
This makes water-driven injectors well suited to nurseries, greenhouses and remote blocks where running power to the injection point is impractical. Browse our water-driven injector range.
Any system that injects fertiliser or chemical into a water line creates a risk of that solution flowing back toward the supply if pressure drops. In Australia, connections of this kind are generally treated as a high hazard and require appropriate backflow prevention, with the specific device and testing requirements set by your local water authority and the relevant plumbing standards.
We supply backflow prevention products alongside our injectors so the installation is considered as a whole. Confirm the requirements for your site with your water authority or a licensed plumber before installing.

No. Water-driven proportional injectors run on the flow and pressure of the irrigation water alone and need no electrical connection. This makes them well suited to greenhouses, nurseries and remote blocks where running power to the injection point is impractical or unsafe.
Injecting fertiliser or chemical into a water line is generally treated as a high hazard in Australia and requires appropriate backflow prevention to protect the supply. The specific device, installation and testing requirements are set by your local water authority and the relevant plumbing standards, so confirm what applies to your site with your water authority or a licensed plumber.
The right ratio depends on your stock solution strength, your target nutrient concentration and your flow rate. Injectors are available across a wide span of adjustable and fixed ratios, so the usual approach is to work back from your recipe and line flow. Our team can size an injector to your system.
Yes. Proportional injectors handle fertiliser, nutrients, pest and disease control products, line cleaning chemicals and other water-soluble products, provided the material is compatible with the injector's seals. Always follow the product label for rates and handling, and check chemical compatibility before use.
Line cleaning chemicals can be injected through the irrigation system to break down biofilm, algae and mineral build-up that block emitters and reduce uniformity. Injectors such as AquaBlend Xtreme are designed to be compatible with water line cleaning chemicals, which lets you dose treatment and nutrient through the same system.
Yes. We supply, install and service fertigation injectors, dosing pumps, filtration and backflow prevention across Australia from our Northmead facility in Sydney, and we hold local stock of units and spare parts for fast support.
