Product Overview
The Pentair 522473 IntelliChem Chlorine Tank with Tank Mounted Pump is a genuine OEM Pentair chemical feed accessory designed for use with compatible IntelliChem water chemistry automation systems. This assembly provides a dedicated storage tank and integrated dosing pump for feeding liquid chlorine into the pool or spa system when controlled by the IntelliChem controller.

This setup helps automate chlorine dosing, reduce manual chemical handling, and support more consistent sanitizer levels when properly installed, calibrated, and maintained.

Ideal For
Pools and spas using a Pentair IntelliChem chemical automation system that require a dedicated liquid chlorine feed tank with an integrated tank-mounted pump.

Key Features

• Genuine Pentair OEM chemical feed accessory
• Designed for compatible IntelliChem water chemistry controller systems
• Includes chlorine chemical tank with tank-mounted pump
• Used for liquid chlorine chemical feed applications
• Integrated pump design eliminates the need for a separate external feed pump
• Helps support automated sanitizer dosing
• Chemical-resistant tank construction
• Compact equipment-pad design
• Common replacement or add-on component for IntelliChem chemical automation setups
• Professional installation and calibration recommended

Benefits
The Pentair 522473 chlorine tank assembly allows the IntelliChem system to automatically dose liquid chlorine based on system programming and water chemistry demand. The tank-mounted pump design keeps the chemical feed setup cleaner and more organized at the equipment pad while reducing the need for separate pump mounting.

When paired with the proper controller, tubing, injection fittings, and sensors, this tank assembly can help maintain more consistent chlorine levels and reduce daily hands-on chemical dosing.

Important System Note
This is the chlorine tank with tank-mounted pump only. It is not the complete IntelliChem controller system. The IntelliChem controller, sensors, flow cell, tubing, injection fittings, and other accessories may be required depending on the installation.

Always confirm the full chemical automation layout before ordering.

Customer-Facing Q&A

Q: What is Pentair part 522473?
A: Pentair 522473 is an IntelliChem chlorine tank with a tank-mounted pump for compatible Pentair chemical automation systems.

Q: Is this the complete IntelliChem controller?
A: No. This listing is for the chlorine tank and tank-mounted pump assembly only. The IntelliChem controller and sensors are not included unless specifically stated.

Q: What chemical is this tank used for?
A: This model is intended for liquid chlorine feed applications when used with a compatible IntelliChem setup.

Q: Does this include the pump?
A: Yes. This version includes the tank-mounted pump.

Q: What size is the tank?
A: This tank is commonly listed as a 4-gallon chemical tank.

Q: Can this be used with acid instead of chlorine?
A: Do not interchange chlorine and acid systems unless the installation has been specifically configured and approved for that chemical use. Chlorine and acid must never be mixed.

Q: Is professional installation recommended?
A: Yes. Chemical automation systems should be installed and calibrated by a qualified pool professional familiar with chemical feeders, sensors, and safe chemical handling.
