The JABSCO macerator pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area.

The JABSCO macerator is self-priming to a five foot lift when the impeller is wet, four foot when dry, and may be mounted in any convenient point in the waste discharge system.

The macerator section grinds waste down to a particle size of 1/8" (3mm) maximum so it can easily by pumped through a 1" (19mm) ID discharge hose.

The pump section is self-priming, permitting the unit to be mounted above the tank in a convenient location. (For optimal efficiency, locate pump as close to holding tank as possible.)

The macerator has an approximate flow rate of 12 GPM (45 LPM) and will empty a typical 30 gallon (115 litres) holding tank in less than 3 minutes.
