The Jabsco 18590 Series Run-Dry Macerator Waste Pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area. This waste tank-empyting macerator pump grinds solids into small particles that easily pass through the 1″ (25mm) discharge port. The Jabsco Macerator is equipped with a protection device that eliminates accidental run-dry. Self-priming to 5′, this pump will empty a typical 30 gallon holding tank in less than 3 minutes. Duty cycle of the pump is 15 minutes continuous, meaning a 180 gallon tank 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.
