Maintenance Recommendation

Impellers should typically be replaced annually or approximately every 200 operating hours, depending on operating conditions. Running a pump dry, sand ingestion, or long idle periods can significantly reduce impeller lifespan.

Regular preventive replacement helps avoid overheating and protects the engine cooling system.
