Jabsco Sealed Macerator Self-Priming Pump 12V

The Jabsco Sealed Macerator is a reliable and efficient self-priming pump designed specifically for marine applications. Equipped with run-dry protection, this DC macerator pump ensures seamless waste evacuation from holding tanks, fish boxes, and livewell tanks, making it an essential addition to any boat.

Effective Waste Evacuation

The Jabsco 18590 series DC macerator pump is the perfect solution for emptying marine holding tanks, especially in areas without discharge restrictions. Its self-priming capability up to 5 feet allows it to efficiently empty a standard 30-gallon (115-liter) holding tank in under 3 minutes. With a duty cycle of 15 minutes continuous operation, you can easily empty up to 180 gallons (680 liters) in a single pump-out session.

For optimal performance and to prevent sediment buildup, it is recommended to flush holding tanks with several gallons of water after each pump-out. This practice helps minimize the risk of potential blockages caused by accumulated debris.

Ideal for Fish Boxes and Livewell Tanks

The Jabsco Macerator Pump excels in emptying fish boxes and livewell receptacles. Often, livewell tanks are positioned above the boat's waterline, allowing gravity to assist in the emptying process. However, if gravity drainage is not feasible, the self-priming and grinding capabilities of the Jabsco macerator pump make it an excellent alternative.

Fish boxes are typically installed below or partially above the waterline and contain various residues like ice, fish scales, and other debris. The Jabsco Macerator Pump's stainless steel cutter effectively reduces these particles to a maximum of 1/8", ensuring smooth operation and preventing clogs. Its self-priming feature is particularly beneficial for the frequently submerged installations found in modern sports fishing boats.
