Dosing Pumps & Fertilizer Injectors

Discover our comprehensive range of dosing pumps, precision-engineered for accurate and consistent chemical injection across a wide range of applications. From small-scale fertigation to industrial water treatment systems, our dosing pump collection includes reliable positive displacement models, solenoid-driven pumps, stepper motor pumps, and proportional injectors.

Whether you're dosing acids, chlorine, fertilisers, polymers, or pH control agents, our pumps deliver unmatched accuracy — drawing precise volumes into a chamber and injecting them into the system via various drive methods. We stock leading dosing pump technologies designed to handle aggressive chemicals and ensure long-term service with minimal maintenance.

This collection also features high-performance fertiliser injectors, widely used in commercial horticulture, nurseries, hydroponics, and greenhouse operations. These units enable accurate application of liquid fertilisers, plant nutrients, wetting agents, and mineral acids — reducing labour, increasing crop quality, and saving water.

Choose from premium dosing pump brands known for performance and reliability. Get free shipping Australia-wide and expert technical support from Land & Water Technology.
