        Description

        Jabsco Sealed Macerator Pumps provide the ideal solution for waste, fish box and livewell tank evacuation.

        Features:

        • The Jabsco 18590 Series DC macerator pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area
        • Self priming to 5 feet this pump will empty a typical 30 gallon (115 Liter) holding tank in less than 3 minutes
        • Duty cycle of the pump is 15 minutes continuous which means a 180 gallon (680 liter) can be emptied in a single operation
        • It is recommended that holding tanks be flushed with several gallons of 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
        • The Jabsco Macerator Pump is the ideal pump for the emptying of fish box and livewell receptacles
        • Very often the livewell tank will be above the waterline of the boat, when this is the case gravity can be used to empty the livewell tank
        • If not installed in this format then it is beneficial to use the Jabsco macerator pump for evacuation due to its self-priming capabilities and also it's grinding properties
        • Fish boxes are typically mounted into the floor of the vessel and are very often below the waterline or only partially above the waterline
        • Again the Jabsco Macerator 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 Macerator Pump, and the self priming capabilities are perfect for fish box installations common to many of today's sports fishing boats

        Rated 5 out of 5 by from Macerator Review It does its dirty job well! Easy to replace. Must keep up with maintenance of the impeller yearly.

        Rated 2 out of 5 by from Very prone to internal leaks We are full time liveaboards. We use this pump on our second head that does not get used, BUT, we operate it and the head once a month with fresh water to exercise the pump, impeller and so on. We have replaced it 3 times and rebuilt it a few. The internal seals fail and water leaks into the motor. The paper gaskets on the housing for the impeller are prone to failure as well. I found that my 3rd pump is leaking water at the motor seal again today on routine maintenance. Time to move on...
