Eheim Replacement Impeller 50Hz for compact ON 600 (7633678)

The Eheim Replacement Impeller (7633678) is a genuine OEM spare part designed specifically for the Eheim compact ON 600 (type 1021) centrifugal pump. The impeller is the rotating component that generates the water flow in the pump — when it becomes worn, chipped, or damaged, the pump output drops, performance becomes noisy, or the unit stops circulating water altogether.

Replacing with a genuine Eheim OEM impeller restores the compact ON 600 to its full rated flow of 250–600 l/h quickly and easily.

Key Features
