The JABSCO 18590 series dc macerator pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area. The JABSCO macerator is selfpriming to a five foot lift when 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, locatepump as close to holding tank as possible.The macerator has an approximate flow rate of 12 GPM45 LPM and will empty a typical 30 gallon 115 literholding tank in less than 3 minutes.The 18590 series waste pump will macerate and pumpall waste and tissue normally found in marine andrecreational vehicle waste systems.
