Johnson Pump 09-1052S-9 Nitrile Impeller for Macerator and Water Pumps

The Johnson Pump 09-1052S-9 is a nitrile replacement impeller built to move water through a marine pump's cooling or discharge circuit. Made from oil-resistant nitrile rubber, it is engineered to match Johnson Pump equipment exactly, which matters for a wear part that has to seal and flex reliably inside a tight pump housing. This impeller is used as the impeller component in the Johnson Pump TA3P10-19 Macerator Pump, where it drives waste flow from the holding tank or bowl discharge outlet.

Because impellers are a wear item, Johnson Pump recommends changing this part every year to keep the pump's cooling or pumping performance consistent and to avoid the dry-running damage that can occur once an old impeller's vanes crack or lose flexibility. The flat-profile design and nitrile compound are chosen specifically for durability under regular wet/dry cycling in marine pump service. Ordering the genuine Johnson Pump 09-1052S-9 ensures the impeller matches your pump's cavity dimensions and drive engagement exactly, rather than relying on a generic substitute.
