Dosatron
Water-powered, electricity-free dosing pumps — a proportional piston driven by line water pressure, spanning 0.02 GPM to 400 GPM.
Dosatron makes water-powered, electricity-free dosing pumps, with a proportional piston driven by line water pressure, spanning 0.02 to 400 GPM. The D14 is its best-selling general-purpose injector, the D14T handles hot caustic and acid CIP sanitation to 158F, and the D132 and D400 inject water-treatment chemicals such as chlorine directly.
What LibertyCES specifies from Dosatron

Water-powered proportional injectors spanning 0.02–14 GPM — D07 is the smallest-flow model in the lineup, D14 is Dosatron's best-selling general-purpose injector.

Max water temperature 158°F with high-temp elastomers and a metal-free wetted path on key versions — built for NaOH and PAA CIP/COP sanitation.

Frequently Asked Questions
How does a Dosatron dosing pump work without electricity?
Every Dosatron model is water-powered — a proportional piston is driven directly by line water pressure, with no electrical connection required, distinguishing the entire lineup from motor-driven or hydraulic-diaphragm dosing pumps.
What temperature and chemistry does the Dosatron D14T support?
The D14T is rated to a maximum water temperature of 158°F with high-temp elastomers, supporting caustic CIP (1-2% NaOH at 160-180°F), acid CIP (0.5-1.5% phosphoric/nitric at 140-160°F), and hot water sanitization up to 171°F.
Which Dosatron models are rated for direct chlorine or PAA injection?
The D132 (35.2-132 GPM) and D400 (110-400 GPM) Mega-Flo injectors are both explicitly marketed for direct water-treatment-chemical injection, including chlorine dioxide, chlorine, and peracetic acid disinfectants.
