Jabsco 18590 Self-Priming Macerator Pump With Run-Dry Protection

The Jabsco 18590 Series DC Macerator Pump is the ideal solution for emptying marine holding tanks when not in a discharge restricted area. Self-priming to 5 ft., this pump will empty a typical 30-gallon holding tank in less than 3 minutes. The duty cycle of the pump is 15 minutes continuous, which means it can empty 180 gallons in a single operation.

The Jabsco 18590 Macerator Pump is also useful for emptying the fish box or livewell when mounted below the waterline. The grinding properties and self-priming capabilities make it beneficial when cleaning out bait reisdue particles, fish scales, or anything else that needs to be easily passed out of the fish box.

The permanent magnet type motor is fully enclosed and has a stainless steel shaft. Includes a run-dry protection device that shuts off the pump. Powder-coated housing with sealed end-bells and bearings. Complies with USCG Regulation 183.410 and ISO 8846 Marine for ignition protection.
