Eheim Replacement Impeller 50Hz for compact ON 3000 (7633738) The Eheim Replacement Impeller (7633738) is a genuine OEM spare part designed specifically for the Eheim compact ON 3000 (type 1031) centrifugal pump. The impeller is the rotating component that generates the water flow in the pump — when it becomes worn, chipped, or damaged, pump output drops, operation becomes noisy, or the unit stops circulating water altogether. Replacing with a genuine Eheim OEM impeller restores the compact ON 3000 to its full rated flow of 1800–3000 l/h and ensures reliable, quiet pump operation.
