DC Macerator Pump 12V (SFMP112001) by Recmar The DC 12V Macerator Pump is a product found in the Boat section of your local wave in the nautical and fishing store under the Pumps category. A macerator pump is a type of pump connected to a toilet (or, in some cases, included in the toilet itself if you buy a macerator toilet). A macerator pump grinds the waste into small particles. The integrated macerator pump in the ceramic grinds the waste before transferring it to the holding tank for black water. Pressing the buttons on the control panel starts the flush cycle. The macerator pump creates a fine slurry from solids and liquids using a stainless steel fast-rotating cutting blade discharged under pressure through small-diameter (3/4-inch or 1-inch) piping.
