How Hydrakos Works
A water-driven motor powers the injection mechanism, proportionally introducing concentrate into the flowing water.
Water flow provides the energy needed to operate the dosing mechanism.
The pump meters concentrate at the selected injection ratio, within its specified operating range.
The treated solution flows onward to its intended application — with no external electrical supply.
Made by SEKO.
