Jabsco Macerator Waste Pump (12V / 45 LPM / 1-1/2″ In / 1″ Out Left)

The Jabsco 18590-2092 macerator pump is the latest version of the Jabsco run-dry macerator waste water pump, which has a fully sealed motor and a new more powerful chopper blade. The sealed motor consists of O-ring sealed end-bells, sealed bearings and a hard durable powder coating to prevent corrosion occurring both internally and externally. A new four-bladed chopper has been added to further reduce the possibility of clogging. The Jabsco macerator pump still has the run-dry feature present in previous models.

The Jabsco 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 115 litre (30 gallons) holding tank in less than 3 minutes. Duty cycle of the pump is 15 minutes continuous which means a 680 litre (180 gallons) 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.

The Jabsco macerator pump is also 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 its grinding properties.
