LibertyCES has documented Metering Pump in Oxidizers/Disinfectants service, including Sodium Hypochlorite, Chlorine Dioxide and Hydrogen Peroxide. Wetted materials to confirm: PVDF, PTFE and Ceramic. Documented models include Blue-White CHEM-FEED CD/MD series and Graco Mongoose PVDF. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
Multiple independent vendors confirm PVDF metering pump wetted parts for NaOCl; ProMinent/AXEON dose ClO2, H2O2, PAA, ozone.
Materials documented for this service
- PVDF (compatible/excellent)
- PTFE (compatible)
- Ceramic (ProMinent electrodes)

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| 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 Industries — Chemical Metering Pumps |
| 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 Industries — Chemical Metering Pumps |
| Graco Mongoose PVDF spec | Part# A21008, 120 VAC, 17 GPD, 250 PSI | Graco — Chemical Injection |
| 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 and Disinfection Systems |
| ProMinent CHLORINSITU III output | On-site hypochlorite/chlorine generation, 100-10,000 g/h chlorine, no chemical transport/storage required | ProMinent — Water Treatment and Disinfection Systems |
| 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 — Mining & Water/Waste Treatment Segment Pages |
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.
