You have just acquired a DOSATRON water-powered dosing pump.
Congratulations on your choice. This model was produced using over 50
years of experience.
Our engineers have developed the DOSATRON series to become one of
the most technically advanced water-powered dosing pumps in the
world.
Over time, this DOSATRON will prove itself to be a most faithful ally.
A few regular maintenance operations will guarantee operation in which
the word “breakdown” will no longer be heard.
IT IS THEREFORE IMPORTANT TO READ THIS MANUAL
CAREFULLY BEFORE USING THE DEVICE.

DOSATRON
Technology
Unique technology that incorporates all dosing functions.
Installed on the water supply line, the DOSATRON uses water pressure as
the only power source. When activated, it draws in the concentrate, doses it
to the desired percentage, and mixes it with the motive water. The resulting
solution is then propelled downstream. The dose of injected concentrate is
always proportional to the volume of water flowing through the
DOSATRON, regardless of variations in flow or pressure in the water supply
line.
