Jabsco Macerator Pump - 115V [18690-0000] - CWR-50782

The Jabsco AC macerator pump unit is the ideal answer to waste handling problems for marine, recreational vehicle and domestic uses. The macerator section grinds waste down to a particle size of 1/8" maximum so it can be pumped easily through a 1" hose discharge line. The pump is self-priming, permitting the unit to be mounted above or below the tank in a convenient location. For optimal efficiency, locate pump as close to the waste source as practical. Empties a 30 gallon holding tank in only 3 minutes. The waste pump will macerate and pump all waste and tissue normally found in marine waste systems. IT WILL NOT HANDLE HARD SOLID OBJECTS, SANITARY NAPKINS OR RAGS.

What our Experts Think

• Efficient Waste Handling: Designed to grind waste down to ~1/8″ particle size for smooth passage through a 1″ discharge hose — keeps plumbing clear and flowing.

• Strong 115 V AC Performance: Continuous‑duty AC induction motor with thermal overload protection delivers reliable power and long service life in marine, RV or stationary setups.

• Flexible Installation: Self‑priming up to ~6 ft, so it can be mounted above or below the holding tank for convenient placement without special priming requirements.

• Quick Pump‑Out Capability: Capable of emptying typical small holding tanks fast (e.g., ~30 gal in minutes), reducing downtime and boosting convenience.

• Durable Marine Construction: Bronze cutter and nitrile impeller materials resist corrosion and wear — essential for marine and sanitation use.

• Use Caveats: Not designed for hard solids, sanitary napkins, rags or similar items — only typical waste and tissue
