Hayward SPX1600R Diffuser Gasket – Replacement Seal for Super Pump / Super II / MaxFlo
Part # SPX1600R — a replacement diffuser gasket designed for select Hayward pool pumps including Super Pump, Super II, MaxFlo, and related models. This gasket seals the diffuser housing to maintain proper water flow and pressure inside the pump.
Key Features
- Chemical-resistant rubber construction suitable for pool water and regular use.
- OEM-spec design ensures a tight seal between diffuser and housing to prevent leaks, loss of suction, or pressure drop.
- Compatible with multiple Hayward pump families — including Super Pump (SP1600X series), Super II (SP3000 series), MaxFlo, and other supported models.
- Easy replacement — remove old gasket, clean surfaces and install the new SPX1600R gasket during regular pump maintenance or rebuild.
Typical Applications
Use this gasket whenever you remove the pump housing for maintenance, seal replacement, or inspection — especially if the old gasket is worn, damaged, cracked, or leaks. It helps restore proper hydraulic integrity and prolong pump life.
Installation & Compatibility Notes
Before working on the pump, turn off power and relieve all water pressure. Disassemble the pump housing to access the diffuser area. Remove the old gasket and clean all sealing surfaces thoroughly. Install the SPX1600R gasket evenly, ensuring full contact and proper alignment. Reassemble the housing, re-prime the pump, and check for leaks or pressure stability before returning to normal operation.
Why Choose This Gasket?
Replacing a worn or degraded diffuser gasket with the correct SPX1600R ensures your pump maintains proper pressure, avoids air leaks, and delivers optimal water circulation — which is essential for filter efficiency and pump longevity.
Maintenance Tips
- Inspect the gasket whenever the pump is opened for cleaning, seal service, or winterization.
- Replace immediately if the gasket is cracked, stiff, flattened, or shows signs of deterioration.
- Ensure sealing surfaces are clean and free of debris or buildup before installing the new gasket to guarantee proper sealing.
- After reassembly, prime the pump carefully and check for stable pressure and absence of leaks during operation.
