Help & FAQs

A Dosatron is a water powered dosing pump that automatically injects a precise amount of liquid concentrate into a flowing water line. The unit operates using the pressure and flow of the water supply, meaning no electricity is required. Dosatron pumps are widely used for agriculture, livestock, horticulture, cleaning and industrial dosing applications.

A Dosatron works by using the flow of water through the unit to drive an internal piston mechanism. As water passes through the pump, it creates a vacuum that draws liquid concentrate from a separate container and mixes it into the water at a precise ratio. The dosing rate remains consistent regardless of changes in water flow within the pump's operating range.

Dosatron dosing pumps are used in a wide range of industries including:

- Fertigation in agriculture and horticulture
- Livestock water medication
- Greenhouse and hydroponic nutrient dosing
- Washdown and cleaning chemical injection
- Water treatment and disinfection
- Pest control and spraying applications
- Industrial chemical dosing

Because they are water powered, they are ideal for remote or off-grid installations where electricity may not be available.

Dosatron pumps offer several advantages compared to electric dosing systems:

- No electricity required
- Highly reliable mechanical design
- Accurate dosing ratios
- Low maintenance
- Simple installation
- Works automatically with water flow

This makes them particularly popular in agricultural and rural environments where reliability and simplicity are critical.

Yes. Dosatron pumps are known for their high dosing accuracy and consistency. Once the dosing ratio is set, the pump maintains that ratio proportionally as water flows through the system. This ensures precise chemical, fertiliser or medication injection.

No. Dosatron pumps operate entirely using water pressure and flow. This makes them extremely reliable and ideal for installations where electricity is unavailable or undesirable.

Yes. Dosatron pumps are designed for continuous operation as long as water is flowing through the system and the pump is operating within its rated pressure and flow limits.

Choosing the right Dosatron pump depends on several key factors including water flow rate, dosing ratio, application, and chemical compatibility. You should first determine the maximum water flow of your system, then select a pump that operates within that range. Next choose the required dosing ratio and the correct seal material depending on the chemicals being injected.

Dosatron pumps are divided into different series based on their flow capacity and application size.

- D07 Series – Compact units for small flow applications such as greenhouses and small livestock systems
- D3 Series – Low flow dosing pumps for precise chemical injection
-D8 Series – Medium flow pumps for agriculture and fertigation
-D20 Series – Designed for moderate to higher flow installations

-D25 Series – One of the most common agricultural dosing pumps with higher flow capacity
- D30 Series – Suitable for large irrigation systems and industrial applications
- D45 Series – High flow pumps for demanding agricultural installations
- D90 Series – Very high capacity dosing pumps for large scale water systems

Selecting the correct series ensures the pump operates accurately and reliably within your system.

The dosing ratio determines how much concentrate is injected into the water. For example:

- 1:100 means 1 part concentrate to 100 parts water
- 1% means 1 litre of product per 100 litres of water

Lower ratios are typically used for fertilisers and nutrients, while higher ratios may be required for cleaning chemicals or disinfectants. Always check the recommended dilution rate of the product being used.

Dosatron pumps are available with different seal materials to suit different chemicals.

AF (Aflas seals)

Best suited for alkaline solutions such as fertilisers, nutrients and many agricultural chemicals.

VF (Viton seals)

Designed for more aggressive or acidic products including acids, disinfectants and certain industrial chemicals.

Selecting the correct seal material helps maximise pump life and reliability.

Standard models

Inject concentrate directly into the water line and are the most common configuration.

Bypass models

Include an integrated bypass system allowing the pump to be isolated from the water line for servicing or when dosing is not required.

Internal Injection models

Designed for applications where injection must occur internally within the pump body rather than externally.

Yes, but it is generally recommended to dedicate a pump to a specific chemical type where possible. This helps prevent cross contamination and ensures seal materials remain compatible with the product being injected.

Your Dosatron pump should be selected based on the maximum water flow rate of your system. The pump must operate within its rated flow range to maintain dosing accuracy. If the flow rate exceeds the pump capacity, the dosing ratio may become inconsistent.

Connection sizes vary depending on the pump series. Smaller models such as the D07 series typically use 20mm (3/4") BSP connections, while larger pumps may use bigger threaded or flanged connections to suit higher flow installations.

Yes. One of the main advantages of Dosatron pumps is that they are proportional dosing pumps, meaning the injection rate automatically adjusts based on the water flow. This ensures the dosing ratio remains consistent even when water demand changes.

Yes. Dosatron pumps are widely used for fertigation, allowing liquid fertilisers and nutrients to be injected directly into irrigation water. This ensures plants receive consistent nutrient levels across the entire irrigation system and helps improve crop growth, efficiency and fertiliser control.

Yes. Dosatron pumps are commonly used to dose medication, vitamins, minerals and supplements into livestock drinking water. Because the pump doses proportionally with water flow, animals receive the correct concentration of treatment regardless of how much water they consume.

Yes. Dosatron pumps are widely used in greenhouses, nurseries and hydroponic systems to inject nutrients and additives into irrigation water. They provide reliable and accurate nutrient dosing without requiring electricity, making them ideal for automated growing systems.

Yes. Dosatron pumps are often used for washdown, sanitation and cleaning applications in industries such as agriculture, food production and transport. They can inject detergents, disinfectants and cleaning chemicals directly into the water line, ensuring consistent chemical dilution during cleaning operations.

Yes. Dosatron pumps can be used for water treatment applications, including dosing disinfectants, scale inhibitors and other treatment chemicals into water systems. This makes them suitable for agricultural water systems, irrigation systems and certain industrial water treatment processes.

Yes. Dosatron pumps can be used to dose liquid pest control products, insecticides or treatment solutions into water systems for spraying or irrigation-based pest management programs. This allows accurate and consistent application of treatment products across large areas.

Yes. Dosatron pumps are used in a wide range of industrial dosing applications, including chemical injection, process dosing and automated dilution systems. Their simple mechanical design and reliable proportional dosing make them suitable for many industrial environments.

Yes. Because Dosatron pumps are powered by water flow rather than electricity, they are ideal for remote or off-grid locations such as farms, irrigation systems and rural water installations where electrical power may not be available.

Yes. Dosatron pumps can be installed directly into irrigation supply lines to inject fertilisers, nutrients or treatment products into the water being distributed across crops, gardens or landscapes. This provides a simple and effective way to automate dosing within irrigation systems.

Dosatron pumps are designed for simple inline installation. The unit is installed directly into the water supply line so that all water flowing through the system passes through the pump. A suction tube is then connected from the pump to the chemical or concentrate container. As water flows through the pump, the concentrate is automatically drawn in and mixed at the selected ratio.

Yes. It is recommended to install a water filter upstream of the Dosatron pump to prevent debris or sediment from entering the unit. Clean water helps protect the internal components and ensures reliable long-term operation.

Most Dosatron pumps are designed to be installed vertically with the injection body facing downward. This orientation ensures proper operation of the internal piston and dosing mechanism. Always follow the installation guidelines provided with the pump model.

Dosatron pumps require a minimum water pressure and flow rate to operate correctly. The exact operating range varies depending on the pump model, but most units operate within standard irrigation and water supply pressures.

While not always required, installing a bypass system is recommended. A bypass allows the pump to be isolated from the water line for maintenance, servicing, or when dosing is not required, without interrupting the water supply.

Yes. Many Dosatron pumps can be installed by farmers, growers, technicians or maintenance staff with basic plumbing knowledge. However, for large or complex systems it may be beneficial to have the pump installed by a qualified technician or irrigation professional.

The dosing ratio is adjusted using the external adjustment sleeve or dial on the pump body. By rotating the adjustment mechanism, you can increase or decrease the amount of concentrate injected into the water. The selected ratio is clearly marked on the pump to ensure accurate and repeatable dosing.

Dosatron pumps are designed to be low maintenance, but periodic servicing is recommended to ensure optimal performance. This typically involves inspecting internal seals, checking the suction tube and foot valve, and ensuring the pump is free from debris or sediment.

Service intervals depend on water quality, operating conditions and the chemicals being used. In most applications, it is recommended to inspect the pump at least once per year or after extended periods of continuous use. Systems using aggressive chemicals may require more frequent servicing.

Yes. Dosatron pumps are designed with replaceable internal components, including seal kits, pistons and other service parts. This allows the pump to be serviced and rebuilt rather than replaced, helping extend the life of the unit.

When switching chemicals or shutting down a system, it is recommended to flush the pump with clean water to remove any remaining concentrate from the internal components and suction tube. This helps prevent chemical buildup and extends the life of the seals.

Dosatron pumps can be used with a wide range of liquid products including fertilisers, nutrients, disinfectants, detergents, acids, livestock medications, vitamins and water treatment chemicals. The key factor is selecting the correct seal material that is compatible with the chemical being injected.

Yes. Dosatron pumps are commonly used for fertiliser and nutrient dosing in agriculture, greenhouses and hydroponic systems. Many fertiliser applications use pumps with Aflas (AF) seals, which are well suited to alkaline nutrient solutions.

Yes, but pumps used with acidic chemicals should generally use Viton (VF) seals, which provide better resistance to acidic and corrosive products. Always check the compatibility of the chemical being used before selecting the pump.

While it is possible, it is generally recommended to dedicate a pump to a specific chemical type where possible. This helps prevent cross-contamination and ensures seal materials remain compatible with the chemical being injected.
