Simple by design

How Hydrakos Works

A water-driven motor powers the injection mechanism, proportionally introducing concentrate into the flowing water.

①
Water enters the pump

Water flow provides the energy needed to operate the dosing mechanism.

②
Concentrate is drawn in

The pump meters concentrate at the selected injection ratio, within its specified operating range.

③
Proportional solution exits

The treated solution flows onward to its intended application — with no external electrical supply.
