Johnson Pump Macerator Pump TA3P10-19, 12V DC, 10 GPM - Model 10-24453-01

The Johnson Pump Macerator Pump, model TA3P10-19 (part number 10-24453-01), is a 12V DC macerator designed to handle marine toilet and holding tank waste. A rotary cutter inside the pump shreds solid waste before it is pumped into or out of the holding tank, allowing the waste to pass through smaller-diameter hose runs than would otherwise be possible. For best performance, mount the pump as close as possible to the holding tank discharge outlet or the toilet bowl discharge outlet, minimizing the length of unmacerated waste line.

Construction pairs a Phenol Plastic (PF) pump body with a Thermoplastic Polyester (PET) housing, a Nitrile impeller (09-1052S-9), a stainless steel shaft, and a lip seal, giving the pump the chemical resistance and durability needed for continuous holding-tank service. The pump moves up to 10 GPM at 0.2 bar and draws 15 amps on a 20 amp fuse, wired to a 12V DC system. Plumbing connects via a 1-1/2 inch hose or 1-1/2 inch BSP inlet and a 1 inch hose outlet, matching common marine sanitation hose sizing. The compact housing measures 9.06 inches long, 4.25 inches wide, and 3.23 inches tall, and the complete unit weighs 4.8 pounds, making it straightforward to fit into tight lazarette or head compartments on boats and RVs.
