Hydrakos D25
11 GPM
Precision chemical injection. Zero electricity.
Reliable, proportional liquid concentrate dosing powered entirely by the water flowing through the pump. Select from three injection ranges, three seal materials and two body materials to match your application.
D25 is the 11 GPM product-family classification. See model-specific operating limits below.
Designed for practical, proportional dosing
The water flow drives the injection mechanism—no external electrical supply is required.
Concentrate is metered in proportion to water flow within the pump's specified operating range.
Choose injection range, seals and body material based on chemical compatibility and process needs.

Amazon purchasing is shown only for the 0.2–2% / FPM / PP configuration associated with the supplied listing; confirm the exact listing configuration before ordering. Other configurations are inquiry-only. Seal/body suitability must be checked for the specific chemical, concentration and temperature.
D25 technical overview
The D25 family is marketed as an 11 GPM pump. The 3–10% variant has a lower specified maximum flow and pressure; refer to the original SEKO documentation for all limits.

Built for a range of liquid-dosing needs
Potential applications include agricultural dosing, livestock watering, turf management, vehicle washing and compatible cleaning or water-treatment processes.
Application suitability depends on chemical compatibility, filtration, water pressure, flow and the selected injection range. Hydrakos pumps are intended for compatible liquid concentrates—not powders.
