For premium tank discharge performance, Dometic T series discharge pumps provide unsurpassed quality and reliability. Unlike impeller-type macerator pumps, the bellow-style T pump can run dry without threat of damage. Efficient operation draws only 6 amps at 12 V DC. In waters where overboard discharge of a waste holding tank is permitted, the T pump integrates with Dometic Tank Discharge (DTD) control systems for completely automated holding tank discharge.
