Install / Failure Note

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.
