Sealed Macerator Pump

Grinding Capabilities – Stainless Steel Cutter capable of grinding waste down to a particle size of 1/8″ (3mm) max.
Capable of passing waste, toilet tissue, fish scales or bait residue. Not designed to pass rags, kitchen towels, tampons, wet wipes or sanitary napkins.

Waste Removal Pump

The Jabsco 18590 series 24VDC Self Priming Macerating Pump is most often used with marine toilets or small portable toilets such as campervan toilets or waste holding tanks. It is ideal solution for emptying marine, caravan or mobile home waste holding tanks.

It is recommended that holding tanks be flushed with plain water after each pump out. This will reduce the possibility of a continued build up of sediment in the tank which could cause a potential blockage.

Live Bait Tank Emptying Pump

The Jabsco 24VDC Self Priming Macerating Pump is great for emptying fish box and live bait tanks due to its self-priming capabilities and also it’s grinding properties.

If the livebait tank is mounted into the floor of the vessel, below the waterline or only partially above the waterline the Jabsco Macerating pump has the characteristics that lend themselves to this application. The bait residue particles of ice, fish scales and anything else that could potentially be found in the Fish-Box will be easily passed by the Jabsco Macerating Pump, and the self priming capabilities are perfect for common fish box installations.
