Compatibility and Buyer Check
Before ordering, confirm that your Hayward system manual or existing pump label calls for GLX-SP-PUMP-120. This 120V pump should be selected by voltage, part number, and system compatibility, not by product image alone.
If your system uses a 240V pump, review the Hayward GLX-SP 240V peristaltic pump instead of this 120V model. If you are servicing the same chemical feed setup, check the Hayward GLX-SP-TANK acid feed tank replacement, Hayward GLX-SP-ROLLER roller assembly, and Hayward GLX-SP duck bill replacement before replacing only the pump.
What This Peristaltic Pump Does
The peristaltic pump helps move chemical solution from the compatible feed tank through the system tubing. In a properly working setup, the pump works with the tank, tubing, roller assembly, duck bill parts, and controller to support chemical feed operation.
Replacing the pump may help when the old pump is confirmed as the failed part. It will not fix problems caused by a cracked tank, clogged duck bill, worn tubing, incorrect controller setting, wiring issue, or unsafe chemical handling.
Before You Order
Check these details before purchasing:
- Confirm the exact part number GLX-SP-PUMP-120.
- Verify that your system requires a 120V peristaltic pump.
- Compare the pump body, cord, connectors, fittings, and mounting points with your existing part.
- Inspect the feed tank, tubing, roller assembly, and duck bill parts for wear or clogging.
- Confirm whether the issue is pump failure or a blocked feed line.
- If you are checking the broader AquaTrol setup, compare your equipment with the Hayward W3AQ-TROL-RJ AquaTrol salt chlorination system.
- Follow all chemical handling and electrical safety instructions before servicing the system.
Installation and Safety Notes
Turn off power to the pool equipment and chemical feed system before removing the old pump. Because this is an electrical part used around pool equipment and chemical feed components, installation should be handled carefully.
Before disconnecting the old pump, take clear photos of wiring, tubing, fittings, and mounting position. Install the replacement pump in the same location and orientation as the original. Do not force connectors, reuse damaged tubing, or operate the pump if wiring looks loose, burned, or corroded.
After installation, check the system for leaks, proper feed movement, and normal operation before leaving it unattended.
Maintenance Tips
To help protect the replacement pump:
- Inspect tubing and fittings during routine service.
- Replace worn or brittle tubing when needed.
- Keep the chemical feed tank clean and properly closed.
- Check duck bill parts if the pump runs but does not feed correctly.
- Do not run the pump dry unless the manufacturer instructions allow it.
- Keep electrical connections protected from moisture.
- Follow Hayward service instructions for pump, tubing, and chemical compatibility.
