LibertyCES has documented Diaphragm Pump in Oxidizers/Disinfectants service, including Sodium Hypochlorite and Hydrogen Peroxide. Wetted materials to confirm: PTFE, UHMWPE and PVDF. Documented models include Graco ChemSafe 1590/515/307/1040. Compatibility depends on exact concentration, temperature and duty cycle, so confirm with a free spec review.
Notes from the vendor documentation
ChemSafe line explicitly positioned for corrosive/oxidizing chemical service with zero exposed metal in fluid path.

Real Specifications
| Spec | Value | Source document |
|---|---|---|
| ChemSafe fluid path materials | PTFE or UHMWPE corrosion-resistant fluid paths, no exposed metals in the wetted section | Graco — Diaphragm Pumps |
| ChemSafe 515/307/1040 construction | PTFE seat, PTFE ball, overmolded PTFE diaphragm, PTFE fluid path, NPT port | Graco — Diaphragm Pumps |
| ChemSafe design advantage | Precision-machined design stated to give superior chemical containment vs. molded pumps; removable air motor for easier maintenance | Graco — Diaphragm Pumps |
Graco's own framing for ChemSafe is explicit: zero exposed metal in the fluid path is a direct design response to the corrosion failure a metal-wetted diaphragm pump risks on hypochlorite or peroxide service, not a cosmetic upgrade.
Sodium hypochlorite and hydrogen peroxide corrode exposed metal fast — Graco's ChemSafe line is machined with zero exposed metal in the fluid path for exactly that reason, which is why it's positioned as its own line rather than sold as a material option on the standard Husky.
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.
