About This Item
OEM Chlorine Storage Container for the Pentair IntelliChem Chemical Controller
The Pentair IntelliChem Chlorine Container (521397) is the OEM replacement chlorine storage container designed for use with the IntelliChem Water Chemistry Controller system. This container is sold without a dosing pump — a separate external pump is required for operation.
⚠️ IMPORTANT: DOSING PUMP NOT INCLUDED — SOLD SEPARATELY
This container does not include a dosing pump. You must supply a separate external pump, or upgrade to the pump-equipped tank version, Pentair part number 522474.
The IntelliChem chlorine container provides dedicated, purpose-built storage for liquid chlorine within the IntelliChem automated water chemistry system. Paired with a compatible dosing pump, it delivers measured chlorine additions to the pool in response to ORP and pH readings from the IntelliChem controller — keeping chemical dosing precise and consistent without manual intervention. Replacing a damaged or degraded container restores the integrity of the chemical feed path and ensures accurate metering from the pump inlet.

Pro Tip
If your IntelliChem system requires a complete chlorine feed assembly, consider Pentair part number 522474 — the pump-equipped tank version — rather than sourcing a separate pump independently. If you already have a compatible external dosing pump in service, confirm its inlet fitting size and tubing compatibility against your IntelliChem installation manual before connecting this container.
