Product Overview

The Pentair IntelliChem Flow Switch (model 754000440) is a precision paddle-style flow sensor designed for use with IntelliChem and other compatible chemical control systems. It includes a built-in magnet and comes with a 10-foot cable for flexible installation. This flow switch monitors sample-cell water flow and disables chemical feed when flow falls below safe levels—helping prevent over-feeding, equipment damage, and ensuring reliable chemical delivery.

Ideal For

• Pool service professionals or facility operators replacing a defective flow switch in a Pentair chemical control system.

• Systems where intermittent chemical feed is caused by low or inconsistent flow, leading to safety or performance issues.

• Installations where automated chemical controls must verify flow before allowing product dosing.

• Customers seeking a genuine OEM part to maintain control system integrity and warranty compliance.

Key Features

• Paddle-Style Magnetic Flow Sensor – detects water flow via a magnetic mechanism recorded when fluid moves through the sample cell.

• 10′ Integrated Cable – generous wiring length for flexible mounting or retro-fits.

• OEM Compatible – designed specifically for IntelliChem controllers and sample cells.

• Ensures Safe Chemical Feed – disables dosing when flow is insufficient, protecting equipment and maintaining balanced water chemistry.

• Easy Replacement – installs in the existing sample-cell port; minimal downtime.

• Durable Construction – built for chemical-control environments and regular pool service conditions.

Customer-Facing Q&A

Q: What does this flow switch do?
A: It monitors flow in the sample cell of the chemical control system and prevents the system from feeding chemicals if water flow is too low or interrupted—protecting your equipment and maintaining safe chemical application.

Q: Is this compatible with my IntelliChem controller?
A: Yes—this model is intended for IntelliChem systems and other compatible Pentair setups. Always check your controller and sample-cell port to confirm fit.

Q: Can I install this myself?
A: Yes, if you’re comfortable working with pool automation equipment. Turn off the power, remove the old switch from the sample cell port, connect the new part, and restore power.

Q: Why is the cable so long (10′)?
A: The generous cable length gives you flexibility in equipment-pad layouts, allowing the controller or sample cell to be positioned farther from the switch if needed.

Q: What happens if the flow switch fails?
A: If the switch fails, your chemical control system may refuse to feed chemicals or could feed incorrectly—leading to potential imbalance or damage. Replacing it restores reliable operation.
