How to Choose the Right Chemical Dosing Pump for Your Application
Choosing the right chemical dosing pump depends on what you are dosing, how much water is flowing through the system, the required dosing ratio, and whether you need a water powered or electronic dosing solution.
At AgriDosing, we supply a wide range of chemical dosing pumps for agriculture, fertigation, livestock medication, water treatment, washdown, chlorine dosing and industrial applications. This guide will help you understand the main types of dosing pumps available and which option may suit your application best.
What is a Chemical Dosing Pump?
A chemical dosing pump is designed to inject a measured amount of chemical, fertiliser, medication, disinfectant or additive into a water line or process system.
Dosing pumps are commonly used for:
- Fertigation
- Livestock medication
- Chlorine dosing
- pH correction
- Water treatment
- Irrigation systems
- Washdown and cleaning
- Industrial chemical dosing
- Hydroponics and greenhouse growing
The right pump will depend on your application, flow rate, dosing ratio, chemical compatibility and installation requirements.
Water Powered Dosing Pumps
Water powered dosing pumps are one of the most popular options for agriculture, irrigation and livestock applications.
These pumps use the flow of water passing through the unit to drive the dosing mechanism. This means they do not require electricity, making them ideal for rural, agricultural and remote installations.
Water powered dosing pumps are commonly used for:
- Fertiliser injection
- Stock medication
- Animal health treatments
- Irrigation chemical dosing
- Greenhouse and hydroponic feeding
- Proportional dosing where the chemical dose needs to match the water flow
Popular options include Dosatron, Tefen MixRite and Mixtron water powered dosing pumps.
Electronic Chemical Dosing Pumps
Electronic dosing pumps are commonly used where accurate chemical metering is required, especially in water treatment, chlorine dosing, pH correction and industrial applications.
Unlike water powered pumps, electronic dosing pumps use an electric motor or solenoid to dose chemical at a controlled rate. These pumps are often selected where the dosing rate needs to be adjusted manually, controlled by instruments, or matched to a process requirement.
Electronic dosing pumps are commonly used for:
- Chlorine dosing
- Acid dosing
- pH correction
- Water treatment plants
- Industrial chemical dosing
- Cleaning and washdown systems
- Boiler and cooling tower dosing
- Swimming pool and process water treatment
EMEC electronic dosing pumps are a popular option for these applications, with different models available for standard chemical dosing, self-venting chlorine dosing and advanced digital control.
Choosing the Right Pump by Application
Different applications require different types of dosing pumps. Below is a general guide to help narrow down the most suitable option.
Fertigation Dosing Pumps
For fertigation, a water powered dosing pump is often the best choice. These pumps dose fertiliser proportionally to the water flow, which helps maintain a consistent fertiliser concentration throughout the irrigation cycle.
Best options for fertigation include:
- Dosatron water powered dosing pumps
- Tefen MixRite dosing pumps
- Mixtron water powered dosing pumps
Livestock Medication Dosing Pumps
For livestock medication, proportional dosing is important because the treatment needs to be mixed accurately into the drinking water supply.
Water powered dosing pumps are commonly used for poultry, pigs, cattle, sheep and other livestock systems because they operate without electricity and dose in proportion to the water flow.
Best options for livestock medication include:
- Dosatron dosing pumps
- Tefen MixRite dosing pumps
- Mixtron dosing pumps
Chlorine Dosing Pumps
For chlorine dosing, an electronic dosing pump is usually the better option. Chlorine can release gas during dosing, so self-venting pump heads are often recommended to reduce vapour lock and improve dosing reliability.
Best options for chlorine dosing include:
Acid Dosing Pumps
Acid dosing requires careful pump selection because not all materials are suitable for acidic chemicals.
For acid dosing, it is important to choose a pump with compatible wetted materials, seals, balls and tubing. VF Viton and other acid-compatible configurations are commonly used depending on the specific chemical.
Alkaline Dosing Pumps
Alkaline chemicals also require the correct seal and material selection. AF Aflas and other alkaline-compatible options may be more suitable depending on the chemical being used.
Water Treatment Dosing Pumps
Water treatment systems often require accurate and reliable dosing of chlorine, acid, alkali, coagulants, flocculants or other treatment chemicals.
Electronic dosing pumps are commonly used in water treatment because they allow more controlled chemical injection and can often be paired with control instruments.
Best options for water treatment include:
- EMEC electronic dosing pumps
- EMEC self-venting chlorine dosing pumps
- EMEC digital dosing pumps
- Eutech water quality testers
- ARAD water meters
Choosing by Flow Rate
Flow rate is one of the most important factors when choosing a dosing pump.
Water powered dosing pumps are selected based on the amount of water passing through the unit. If the water flow is too low, the pump may not operate correctly. If the flow is too high, the pump may be undersized for the system.
Common flow rate considerations include:
- Minimum operating flow
- Maximum operating flow
- Pipe size
- Irrigation zone flow rate
- System pressure
- Required chemical dose
Choosing by Dosing Ratio
The dosing ratio determines how much chemical is injected into the water stream.
For example, a dosing ratio of 1% means 1 part chemical is injected for every 100 parts water. Some applications require very low dosing rates, while others need stronger chemical concentrations.
Common dosing ratio ranges include:
- 0.03–0.2%
- 0.2–2%
- 0.4–4%
- 1–5%
- 3–10%
Fertigation and livestock medication often use lower dosing ratios, while cleaning, washdown or treatment applications may require higher dosing ranges.
Choosing by Chemical Compatibility
Chemical compatibility is critical when selecting a dosing pump.
Different chemicals can affect pump seals, bodies, valves, balls, tubing and other wetted parts. Choosing the wrong material can lead to swelling, cracking, corrosion, leaks or premature pump failure.
Common seal options include:
- VF Viton for many acidic applications
- AF Aflas for many alkaline applications
- NBR for selected neutral or less aggressive chemicals
- EPDM for selected chemical and water treatment applications
Always check chemical compatibility before selecting a pump. If you are unsure, contact AgriDosing with the chemical name, concentration, temperature and application details.
Choosing by Brand
AgriDosing supplies a range of trusted dosing pump brands to suit different applications and budgets.
Dosatron
Dosatron dosing pumps are widely used for water powered proportional dosing in agriculture, fertigation, livestock and irrigation systems. They are a strong choice where reliable proportional dosing is required without electricity.
Tefen MixRite
Tefen MixRite dosing pumps are a popular option for cost-effective water powered dosing. They are commonly used for fertigation, livestock medication, irrigation and general proportional dosing applications.
Mixtron
Mixtron dosing pumps offer a broad range of water powered dosing options for agriculture, livestock, horticulture and industrial applications. Different seal types and dosing ratios are available depending on the chemical and application.
