Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Dosatron D132 flow/injection range | 35.2–132 GPM; injection ratios from 1:30,000 to 1:100 depending on model (D132MZ30000/5000/1) | Dosatron — Water-Powered Dosing Pumps |
| Dosatron D400 flow/injection range | 110–400 GPM; injection range 0.003%–0.5% (1:30,000 to 1:200) | Dosatron — Water-Powered Dosing Pumps |
| Dosatron lineup flow-capacity spread | D07 (0.02 GPM min) to D400 (400 GPM max) — three orders of magnitude across the lineup | Dosatron — Water-Powered Dosing Pumps |
| AXEON XP-Series output/turndown | 4–30 GPD output, 20:1 turndown ratio, peristaltic metering pump | AXEON Water Technologies — Filtration, Ion Exchange, Disinfection & Injection Systems |
| Dosatron Venturi proportioner | Self-cleaning polypropylene, built-in check valve preventing back-fill into the concentrate tank | Dosatron — Water-Powered Dosing Pumps |
Dosatron's Venturi proportioner includes a built-in check valve specifically to stop line water from back-filling into the chemical concentrate tank — a real backflow failure mode in electricity-free proportional injection that a cheaper venturi without that check valve won't catch.
The Dosatron line runs entirely off line pressure with no electrical failure point, but flow capacity spans three orders of magnitude between the D07 and D400 — on a mis-specified job the risk isn't the technology, it's undersizing or oversizing the proportioner for the flow it actually has to see.

Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
