Oase Fountain Pump Replacement Impellers

Genuine OASE replacement impeller assemblies for the OASE Fountain Pump line. These pumps — used in statuary, decorative wall fountains, small water features, and pondless displays — rely on the impeller to move water quietly and reliably. When flow drops, gets noisy, or the pump stops priming, the impeller is typically the first service part to replace. These assemblies are model-specific; match your Fountain Pump model number to the correct impeller size below.
