Eheim Replacement Impeller 50Hz for compact ON 1000 (7633698)

The Eheim Replacement Impeller (7633698) is a genuine OEM spare part designed specifically for the Eheim compact ON 1000 (type 1022) 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 1000 to its full rated flow of 250–1000 l/h and ensures reliable, quiet pump operation.

Key Features

• Genuine Eheim replacement part: Exact OEM fit for the Eheim compact ON 1000 (type 1022) — no compatibility guesswork

• 1 impeller per pack
