"Why do I need a macerator pump?"
Because a uniform slurry is more easily pumped than raw toilet waste.
Whether discharge is overboard (at sea), or from a holding tank to a shore pump-out station, waste that has been macerated is pumped faster, with less risk of annoying and unpleasant blockages, and with less load on the pump.
JABSCO macerator pumps have 38mm (1½") bore inlet ports for efficient handling of solids. The pump takes in raw waste, and grinds it to a consistency that can be safely discharged via 25mm (1") bore pipework.
JABSCO macerator pumps are designed to handle normal toilet waste and easily-disintegrated toilet tissues. They will not handle high wet-strength tissues, sanitary towels, napkins, diapers, rags or hard objects.
Pumping out the toilet waste holding tank
Never the most welcome of tasks, emptying the toilet waste holding tank requires a robust reliable pump that will do the job with the minimum of fuss.
If a shore pump-out station can do the job for you - no problem! But for the times when you need your own pump on board, choose a JABSCO electric or manually-operated pump designed for the purpose - simple, efficient and fully serviceable.
No Jabsco pump should be used for petrol, solvents or any liquid with a flash point below 37oC( 98oF)
