The clip-on heat sink is designed to improve cooling for continuous-duty pumps. When attached to the pump, it creates an airflow channel around the housing, allowing heat to dissipate more efficiently. This helps prevent overheating and extends the pump's continuous operating time. Compatible with all INDFLO pumps except the DP22, DP23, and DP53 series.
