As an official distributor, we supply and service SEKO dosing and metering pumps in Australia for water treatment and a wide range of industrial applications. Our team can assist with pump selection and configuration according to your required dosing rate, discharge pressure, chemical compatibility, control method and process conditions.
The SEKO Dosing and Metering Pumps Range
SEKO manufactures a comprehensive range of chemical dosing and metering pumps for accurately introducing chemicals and other additives into water and industrial processes. From electronically controlled solenoid dosing pumps to air-operated double-diaphragm and water-driven dosing technologies, the range provides solutions for different flow rates, pressures, control requirements and operating environments.
Fulfil Dosing Duties With Accuracy, Consistency and Flexibility
Selecting a dosing pump involves more than matching a required flow rate. Chemical compatibility, operating pressure, required dosing accuracy, control signals, viscosity, solids content and available utilities can all influence which pump technology and configuration is appropriate.
SEKO is a globally trusted name for dosing, metering and transfer pumps that are perfect for water treatment, industrial processing and other applications where chemicals or additives must be introduced or transferred reliably.
Depending on the selected model and configuration, these pumps handle applications such as:
- Chemical dosing and industrial process chemical addition
- Wastewater and potable water treatments
- Agricultural and fertigation (fertiliser + irrigation) systems
- Food and beverage processing
- Cooling-water treatment
- Cleaning and wash systems
- Slurries, viscous and solids-laden fluid handling

SEKO Solenoid Dosing Pumps
Solenoid-driven diaphragm pumps provide accurate, repeatable chemical metering. They are particularly suited to applications where relatively small quantities of chemicals must be introduced at a controlled rate.
We offer three SEKO solenoid dosing pump ranges: Tekba, Tekna and Kompact. These include base-mounted and wall-mounted configurations. Different models built with chemically resistant materials offer you a variety of control options (analogue or digital), so you can automate constant or proportional dosing.
Tekba Series
SEKO Tekba base-mounted solenoid diaphragm dosing pumps are designed for reliable chemical dosing in water-treatment and related applications. These provide constant or proportional dosing depending on the selected version, with analogue and digital inputs available for integration with external controls.
Features and options include:
- Mechanical stroke-length adjustment for dosing output regulation
- Stabilised multi-power supply
- Can handle flow rates from 2.5 to 110 L/h, and pressures up to 20 bar
- Liquid-end components in PVDF, PTFE, EPDM, FPM and ceramic materials
- IP65 protection
- Low-level alarm capability
- Optional dosing accessories (e.g., multifunction valves, automatic degassing heads and flow sensors)
Tekna Series
SEKO’s versatile Tekna range of wall-mounted solenoid dosing pumps offers both simple constant-rate and proportional dosing, with analogue and digital interfaces.
AKL, AKS, APG, TPG, TPR, TCK, TPT and ATEX models allow you to match a specific pump and control system to your particular requirements. Depending on the model, functions can include 4–20 mA or pulse-controlled proportional dosing, batch operation, programmable timing and other automated dosing functions.
Features and options include:
- Handles flow rates from 0.4 to 110 L/h, with pressures up to 20 bar
- Multiple control configurations
- Chemical-resistant wetted materials
- 12 VDC power supply for the Tekna TPT model for solar-powered installations
- ATEX-certified Tekna model for specific applications in designated hazardous areas
Kompact Series
For smaller chemical dosing and metering duties, SEKO’s Kompact series provides compact wall-mounted solenoid pump solutions.
Models within the Kompact range include AMS, AML, AMC, DPT and DRP configurations, providing different control options for small-volume dosing applications. A stabilised multi-power supply helps optimise electrical consumption while protecting dosing performance against fluctuations in the incoming supply.
Features and options include:
- Compact wall-mounted design
- Constant and proportional dosing options
- Handles flow rates up to 5 L/h and pressures up to 10 bar
- Chemically resistant components, including PTFE diaphragms, ceramic ball valves and PVDF/PVDF-T pump heads
- IP65 enclosure protection
SEKO Air-Operated Double-Diaphragm (AODD) Pumps
If you’re dealing with substantially greater flow rates or more difficult liquid chemicals, air-operated double-diaphragm (AODD) pumps could be the solution for you.
Duotek Series
These AODD pumps operate using compressed air and contain no electrical drive components. They can handle highly viscous and abrasive liquids, including fluids containing suspended solids. The absence of electrical components allows suitable configurations to be fully submerged without affecting pump operation. An all-bolted construction provides additional resistance against leakage.
Duotek pumps are also compact and portable, making them suitable for duties where a pump needs to be moved between different locations.
The Duotek range includes models from the compact AF0007 and AF0018 through to higher-capacity models including the AF0400, AF0700 and AF1000. Pump size, construction materials and diaphragm selection can be matched to the required flow rate and characteristics of the pumped liquid.
Features and options include:
- Handles flow rates from 8 to 1,000 L/min, and pressures up to 8 bar
- Handles viscous and abrasive fluids; suitable for liquids containing suspended solids
- All-bolted, seal-free construction
- Dry-running capability
- Portable and trolley-mounted configurations available for mobile operation
- Multiple casing and diaphragm materials (e.g., polypropylene, PVDF, SS316 stainless steel, aluminium and POM-C)
Arkad Series
Arkad is SEKO’s next-generation AODD platform, made for the most demanding industrial chemical dosing and liquid transfer duties, especially for water and industrial applications. Its pump architecture is updated for better leak prevention, diaphragm life, anti-stall operation, pneumatic efficiency, reduced icing/noise, serviceability and chemical resistance.
Arkad is available in multiple pump sizes to accommodate different flow rates, fluid viscosities and particle sizes.
Features and options include:
- One-piece manifold, intended to eliminate the leakage risk (associated with multi-piece manifold designs)
- All-bolted, seal-less construction
- A specially designed exhaust chamber with a double silencer, for reduced icing and noise
- Handle flow rates from approximately 7 to 880 L/min
- Maximum air pressure up to 8 bar
- Variable flow and head control
- Dry-running and dry self-priming capabilities
- Safe deadheading
- Cavitation tolerance
- Submersible configurations available
- Low-shear fluid handling
- High-viscosity and solids-handling capability
SEKO Hydrakos Water-Driven Dosing Pumps
If you require chemical dosing pumps without the use of an electric motor or solenoid, the Hydrakos pump series could be your solution.
These pumps are installed directly into the water supply line. They use the pressure and flow of the water itself to power the dosing mechanism. The amount of chemical injected remains proportional to the volume of water passing through the pump, without relying on electrical power or a separate electronic dosing-control system.
Hydrakos pumps can be used for applications in water treatment, industrial processes, fertigation, livestock farming, food and beverage processing and other duties with a flowing water supply.
Features and options include:
- Water-powered operation; no electrical supply required
- PP and PVDF body materials
- Self-priming operation
- Accommodates flow rates from 10 to 2,500 L/h and operating pressures from 0.3 to 6 bar
- Adjustable dosing concentrations of 0.2–2%, 1–5% and 3–10%
- Concentrated additive injection rates from 0.02 to 200 L/h
- Efficient chemical mixing
- Automatic cessation of dosing when water flow stops
- Portable configurations for applications such as emergency skids
- Low operating and maintenance requirements
