Jabsco Macerator Pump Series

Sealed Macerator
Self-Priming Macerator Pump with Run-Dry Protection
Waste 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 5ft 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.
