Run-Dry Macerator Waste PumpWASTE EVACUATIONThe 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.
FISH BOX AND LIVEWELL TANK EVACUATIONThe 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 buy the Jabsco Macerator Pump, and the self priming capabilities are perfect for fish box installations common to many of today's sports fishing boats.

The Jabsco 18590-2094 series DC macerator pump is engineered for efficient waste evacuation and livewell management on boats. Designed with a self-priming capability up to 4 feet, this pump can empty a typical 30-gallon (115-liter) holding tank in less than three minutes, making it an ideal solution for marine waste disposal in areas where discharge restrictions are relaxed. Its duty cycle allows continuous operation for up to 15 minutes, enabling the evacuation of larger volumes such as 180 gallons (680 liters) in a single session. Regular flushing of holding tanks with water after pump-out is recommended to prevent sediment buildup, ensuring smooth operation and reducing the risk of blockages. The pump’s robust design includes a triple-sealed motor to prevent internal and external corrosion, extending its lifespan in harsh marine environments. The four-bladed chopper minimizes clogging by efficiently cutting through solids such as fish scales, ice, and other residues commonly found in fish boxes and livewells. The unit detects the absence of fluid and automatically shuts off to prevent impeller damage, and its sensor provides an adequate run-dry period for initial priming. Resetting the pump is straightforward—simply interrupting the power supply resets the run-dry protection. The flow rate of up to 12 gallons per minute ensures quick and reliable evacuation of waste or bait residues. Its inlet port is compatible with 1-1/2-inch hose barb and 1-1/2 NPT fittings, while the discharge port supports a 1-inch hose barb connection. This versatile pump is suitable for various applications, including marine waste tanks, fish boxes, and livewells, especially where gravity alone cannot drain the receptacles effectively. Its compact size and durable construction make it a preferred choice for sport fishing boats and other marine vessels requiring efficient waste management solutions.
