Real Specifications
| Blue-White NaOCl diaphragm rating | DiaFlex/PVDF diaphragm rated E (Excellent) for 25% sodium hypochlorite in water, 28-day immersion test at 73°F | blue-white-chemical-metering-pumps.md |
| Blue-White NaOCl tube ratings | Flex-A-Prene and Flex-A-Chem tubing both rated E (Excellent) at 12.5% and 25% NaOCl; Flex-A-Thane rated G (Good) at both concentrations | blue-white-chemical-metering-pumps.md |
| Graco Mongoose PVDF spec | Part# A21008, 120 VAC, 17 GPD, 250 PSI | graco-chemical-injection.md |
| ProMinent Bello Zon CDKd capacity | Chlorine dioxide 7.5-12,000 g/h, treats water flows up to 60,000 m³/h | prominent-water-treatment-systems.md |
| ProMinent CHLORINSITU III output | On-site hypochlorite/chlorine generation, 100-10,000 g/h chlorine, no chemical transport/storage required | prominent-water-treatment-systems.md |
| Hayward Z Series Digital dosing modes | 1-29 GPH across 3 size tiers; Digital model adds closed-loop pH/Redox Control dosing, a mode the Analog model does not have | hayward-flow-control-web-additions.md |
Hayward's own model-code taxonomy confirms the pH/Redox Control mode ("R") has no Analog-series equivalent — ordering the Analog Z Series for an oxidizer application that actually needs closed-loop pH/ORP-linked dosing is a real, catalog-documented mis-spec risk, not a hypothetical one.
Sodium hypochlorite dosing lives or dies on wetted-material choice, not price — Blue-White's own 28-day immersion testing rates DiaFlex PVDF Excellent for NaOCl up to 25% concentration, the same material Graco independently rates highly elsewhere; James Riggins treats that cross-vendor agreement as the real basis for a chlorine metering spec, not a single catalog claim.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
