Product Warranty
Product Warranty
Dosatron products are covered by a 12-month warranty from the date of purchase for manufacturing defects only.
To claim warranty, the product must be returned to the manufacturer or authorised distributor with proof of purchase. The unit will be inspected and repaired or replaced if the defect is confirmed.
CONDITIONS
- Product must be rinsed and free of chemicals before return.
- Return postage is paid by the customer.
- Warranty repairs do not extend the original warranty period.
NOT COVERED
- Incorrect installation or misuse
- Lack of maintenance
- Environmental damage or corrosion
- Seal wear (consumable parts)
- Damage caused by water impurities such as sand
REQUIREMENTS
A filter (approx. 60 micron / 250 mesh) must be installed upstream of the Dosatron for the warranty to remain valid.

Description
Description
The Dosatron DIA4ALVF is a robust aluminium water powered dosing pump designed for precise proportional injection of chemicals directly into flowing water lines. Featuring an adjustable dosing range of 1–4% (1:100 to 1:25), this model is ideal for applications requiring higher dosing concentrations while maintaining reliable and consistent chemical injection.
Powered entirely by water flow, the DIA4ALVF operates without electricity using a hydraulic diaphragm motor. As water passes through the unit it drives the internal motor, which simultaneously activates the dosing piston to draw concentrate from a chemical container and inject it into the water stream. This design ensures the dosing rate remains proportional to the volume of water entering the pump regardless of variations in pressure or flow.
Constructed with a durable aluminum body, the DIA4AL series is designed for demanding industrial, agricultural and water treatment environments where strength, reliability and chemical compatibility are essential.
Common Applications
- Fertigation and nutrient injection
- Acid injection for irrigation systems
- Livestock medication dosing
- Industrial chemical injection
- Water treatment and sanitation systems
Key Features
- Water powered operation – no electricity required
- Adjustable dosing range from 1–4%
- Diaphragm driven hydraulic motor for reliable operation
- Heavy-duty aluminum body for industrial environments
- Consistent proportional dosing independent of pressure variations
- Inline installation for simple integration into water systems

Dosatron DIA Series Proportionate Dosing Pumps
The Dosatron DIA Series is a water-powered diaphragm metering pump range designed for applications requiring the injection of more aggressive, viscous, or sensitive liquid products that may not be suitable for standard piston-style dosing pumps. Powered entirely by water flow, the DIA range uses a diaphragm-based dosing mechanism to accurately draw and inject concentrate into the water line without electricity.
The DIA Series is particularly suited to chemical injection, industrial dosing, washdown systems, sanitation, water treatment, and specialised agricultural applications where product compatibility is critical. It is commonly used for dosing acids, alkaline chemicals, viscous additives, corrosive solutions, and other challenging liquids, making it a more specialised solution compared to standard fertigation-focused Dosatron ranges.
How a Dosatron Works
A Dosatron operates using the flow and pressure of water to automatically draw and mix liquid additives into the water line. As water passes through the unit, an internal piston creates a suction effect that pulls concentrate from a chemical container.
The product is then precisely mixed with the water at the selected dosing ratio, ensuring consistent and accurate injection without the need for electricity.
A simple adjustment dial allows the user to set the exact dosing ratio required for their application. As water flow increases or decreases, the Dosatron automatically maintains the same proportional mix, ensuring reliable dosing at all times. This makes it ideal for applications such as fertilisation, livestock treatments, sanitation, and water conditioning where accuracy and consistency are critical.
