How do I replace the impeller on an Aquascape PL or PN pump?

If the impeller on an Aquascape PL or PN Series pump is worn or damaged, it can be replaced without replacing the entire pump.

Replacement impellers

Use the impeller designed for your pump model:

• 3-PL 3000: Impeller #30320
• 5-PL 5000: Impeller #30321
• 9-PL 7000: Impeller #30322
• 8-PN 5500: Impeller #29749
• 12-PN 10,000: Impeller #30422

How to replace the impeller

1. Disconnect power to the pump before servicing it.
2. Remove the pump from the skimmer, intake bay, or Pondless® Waterfall Vault.
3. Remove the pump casing to expose the impeller.
4. Hold the impeller securely and remove the impeller retaining hardware.
5. Remove the old impeller from the motor shaft.
6. Clean away debris, string algae, sand, and mineral buildup from the impeller area.
7. Install the correct replacement impeller for your pump model.
8. Inspect the casing O-ring or gasket and replace it if damaged.
9. Reinstall the pump casing and securely tighten the fasteners.
10. Reinstall the pump, restore power, and check for normal water flow, vibration, noise, or leaks.

Important

Do not disassemble the motor or mechanical seal when replacing the impeller.

If the new impeller does not restore normal pump operation, the pump may require additional service.
