          Jabsco 18590 Sealed Macerator Pump with Run-Dry Protection

          Item # 870877


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


          • 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
