Hayward SPX3021C Impeller, 2-1/2 HP Max Rated / 2 HP Full Rated (Super II SP3000 / SP3000X)

Hayward SPX3021C is a genuine replacement impeller for the Hayward Super II pump family. This impeller is commonly identified as the 2 HP full-rated (often referred to as 2-1/2 HP max-rated in listings) impeller used on compatible SP3000 and SP3000X series Super II pumps. Replacing a worn, cracked, or clogged impeller can restore proper flow and pump performance.

Installation Notes

  • Disconnect power at the breaker and relieve system pressure before servicing.
  • Confirm the pump’s total horsepower (THP) / service factor and match the correct impeller.
  • Replace the pump shaft seal during impeller service to help prevent leaks into the motor.
  • Inspect the diffuser and housing gasket/O-rings and replace any worn seals while the pump is open.
  • Prime the pump properly after reassembly and check closely for leaks.

Maintenance Tips

  • Keep skimmer and pump baskets clean to reduce debris reaching the impeller.
  • Maintain proper water level to help prevent cavitation and impeller wear.
  • Address suction-side air leaks promptly to improve priming and reduce pump strain.
  • If flow drops suddenly, check the filter/baskets first, then inspect the impeller for blockage.
