Description
Replace the impeller in any Blue Thumb Mag-Drive Fountain Pump with the factory-correct OEM part. Each impeller is matched to a specific pump model — match the replacement to the GPH rating printed on your pump housing or to the original PB-series SKU. The 11 sizes here cover the full Blue Thumb Mag-Drive lineup from the 120 GPH Mini through the 1,980 GPH Large. Impellers are consumables and should be replaced annually or at the first sign of reduced flow, noisy operation, or magnet wear.
