LibertyCES has documented Mixer/Agitator in Oxidizers/Disinfectants service, including Sodium Hypochlorite. Wetted materials to confirm: 316SS shaft/impeller. Documented models include Peabody Gemini Mixing/Agitation Systems. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
Peabody's mixer-mount systems are cataloged for tanks that store chemicals including sodium hypochlorite per the same catalog's Special Application Tanks guidance.

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| Sodium hypochlorite storage spec | Max 12.5% concentration, SPG 1.5 (1.9 optional as added corrosion barrier) | Peabody Engineering — General Product Catalog (July 2026) |
| Wetted-component guidance for NaOCl | All non-metallic wetted components; both EPDM and Viton elastomers in active use | Peabody Engineering — General Product Catalog (July 2026) |
| Mixer mount duty ratings | Light Duty FRP to 200 gal, Medium Duty FRP to 1,500 gal, Heavy Duty Mild Steel/FRP over 2,500 gal | Peabody Engineering — General Product Catalog (July 2026) |
| Containment requirement | Double containment recommended for sodium hypochlorite storage | Peabody Engineering — General Product Catalog (July 2026) |
Peabody's own Special Application Tanks guidance calls for all non-metallic wetted components in 12.5% sodium hypochlorite service, even though the mixer-mount hardware itself is cataloged in mild steel or 316 stainless — worth catching before a stainless impeller ends up in direct, continuous NaOCl contact.
James Riggins specs to the wetted-parts material, not the mount hardware catalog page — Peabody sells stainless mixer mounts and 12.5% sodium hypochlorite tanks in the same catalog, but its own chemical-specific guidance recommends non-metallic wetted components for that chemical, and conflating the two is how a impeller gets specified into a corrosion problem.
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.
