New O-Ring sealed motor, twin sealed ball bearings and heavy duty chopper make this macerator pump ideal for evacuating fish boxes and livewell tanks as well as holding tanks. The macerator grinds waste into small particles so it easily passes through the 25mm (1”) discharge port. Can discharge tanks up to 600 liters in one operation and self-primes up to 1,2m. In addition to these features the Jabsco Macerator is now fitted with an exclusive (patent pending) Run-Dry-Protection Device. This new feature makes accidental run-dry impeller damage a thing of the past.
