Jabsco Sealed Macerator Self-Priming Pump 12V

Meet the Jabsco Sealed Macerator Self-Priming Pump 12V, a rugged, reliable solution for fast and clean waste evacuation on your boat. Built to handle holding tanks, fish boxes, and livewells, this compact DC macerator delivers power where you need it most—inside your marine system.

Self-priming to 5 ft means you can evacuate tanks that sit above the waterline with ease. In typical use, it can empty a 30 gallon (115 L) holding tank in under 3 minutes, and its 15-minute continuous duty cycle allows up to 180 gallons (680 L) to be cleared in a single operation. After pump-out, a few gallons of water flush through the tank to minimize sediment buildup and reduce blockages.

Designed for Marine Use

The Jabsco macerator unit features a nitrile compound impeller and a stainless steel cutter, delivering durable performance in harsh marine environments. Its self-priming capability makes it an excellent choice for installations where the tank is below or partially above the waterline, especially in fish boxes and livewells where sediment and bio-residue are common.

Usage and Maintenance

For best results, flush holding tanks with several gallons of fresh water after each pump-out to minimize sediment buildup and reduce the risk of blockages. Regular inspection ensures the grinder remains clear and ready for fast evacuations.
