Our DEF Pumps are specifically designed and engineered for dispensing DEF. Our list ranges from 12 Volt pumps, centrifugal, double diaphragm, Submersible, Smart Start and specialty pumps. Strong delivery pressure makes it ideal for use in supplying DEF from storage tanks. This self-priming pump also has excellent suction capacity even when there are air bubbles in the liquid. Only we give you the original “BENECOR SMART START” technology. Our Smart Start DEF PUMP allows for minimal user interface. Simply squeeze the nozzle and the pump automatically starts THEN shuts-off 12 seconds after the fill is complete.
