SEKO Dosing Pump
We supply SEKO dosing pumps for accurate and reliable chemical dosing in water treatment, wastewater treatment, industrial processes and other applications in China. Different SEKO metering pump series are available for various flow rates, pressures and control requirements.
SEKO Dosing Pump Series
SEKO dosing pumps are precision chemical dosing equipment dedicated to the chemical, water treatment and other industries, primarily designed for accurate transfer of highly corrosive media such as strong acids and strong alkalis.
Its core features include corrosion-resistant construction materials (including PP, PVDF or fluorine-lined structures), precise flow control with tolerance within ±1%, and modular design.
Tekba & Komba Seris
Applications
- Agricultural water treatment
- Food & Beverage
- Industrial water treatment
- Drinking water treatment
- Wastewater treatment
Tekba: Flow rate range: 2.5–110 L/h, maximum pressure 20 bar
Komba: Flow range: 1–9 L/h, maximum pressure 10 bar
Features & Advantages
Stable Dosing Performance
Equipped with an electromagnetic drive algorithm that protects both the pump and the environment.
It offsets the impact of voltage fluctuations on pump operation, ensuring long-term stable running.
Energy Saving
It operates steadily over a wide voltage range (100–240 Vac, 50/60 Hz).
Adopting SEKO patented electromagnetic drive algorithms, it effectively reduces power consumption.
Excellent Chemical Compatibility
Fitted with a PVDF pump head, PVC suction tube, PE discharge tube and ceramic ball valves,
the pump delivers long service life and outstanding chemical resistance, compatible with nearly all chemicals used in water treatment industries.
Safe Wiring
The relay connections of the EMG series adopt IP65-rated circular connectors.
Easy Wiring
The signal ports of the EMG series feature internally threaded terminals,
allowing quick plug-and-play connection with external signal input devices.
Simple Installation
Installation is straightforward without requiring special tools.

Seko Dosing Pump Troubleshooting
- Failure to prime liquid: Inspect whether the strainer on the foot valve is clogged (monthly cleaning is recommended). Verify the airtightness of the suction pipeline. For high-viscosity media, increase the stroke frequency to above 60 Hz.
- Flow fluctuation troubleshooting: If the pressure gauge reading of the pulsation dampener fluctuates by more than 0.05 MPa, inspect the sealing performance of the check valves. An acoustic emission detector can locate worn ball valves; the typical replacement cycle for ball valves is 2,000 operating hours.
- Motor overheating warning: If the temperature rise exceeds 65°C, check whether the cooling fan runs normally. For sites with ambient temperature above 40°C, install an axial fan for forced air cooling.
