Jabsco 18590-2094 Self Priming Sealed Macerator Pump 24V for Marine Waste and Fish Box Evacuation

Run-Dry Macerator Waste Pump

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.

FISH BOX AND LIVEWELL TANK EVACUATION

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 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 a reliable solution for efficient waste evacuation on boats and marine vessels. Designed with a self-priming capability of up to 4 feet and a flow rate of 12 gallons per minute, this pump can empty a typical 30-gallon holding tank in less than 3 minutes, making it suitable for quick and thorough waste management. Its duty cycle of 15 minutes allows for the complete evacuation of larger tanks, up to 180 gallons, in a single operation. Proper flushing of holding tanks with water after each pump-out is recommended to prevent sediment buildup and potential blockages, ensuring long-term operational efficiency.

The Jabsco Macerator Pump is also ideal for evacuating fish boxes and livewell tanks. Many livewells are located above the waterline, allowing gravity to assist in drainage; however, when installed below or partially above the waterline, the pump’s self-priming and grinding capabilities come into play. The pump effectively handles bait residues, fish scales, ice, and other debris, maintaining a clean and functional livewell system. Its ability to pass particles and its sealed, corrosion-resistant motor design make it suitable for marine environments where reliability and durability are critical.

Constructed with a triple-sealed motor to prevent internal and external corrosion, the pump features a four-bladed chopper that reduces clogging by breaking down solids efficiently. The sensor detects the absence of fluid and automatically shuts off the pump to prevent impeller damage, while the run-dry period allows for initial priming without risking equipment failure. Additionally, the pump includes a reset feature via interrupting the power supply, ensuring ease of maintenance. Fitted with a 1-1/2 inch hose barb inlet and a 1-inch discharge port, the pump is compatible with standard marine hoses. This model is a robust, efficient, and versatile solution for waste management and livewell evacuation needs on recreational and commercial vessels alike.
