Jabsco Macerator & Waste Pumps

When it comes to marine sanitation systems, Jabsco has earned a reputation for engineering macerator and waste pumps that combine durability, efficiency, and intelligent design features. For boat owners and marine professionals who demand reliable waste management solutions, Jabsco's macerator pump lineup represents decades of refinement in addressing the unique challenges of marine waste transfer.

Self-Priming Performance and Chopper Technology

Jabsco macerator pumps are self-priming and feature a powerful chopper blade that can handle solids and soft tissue, making them exceptionally versatile for various marine sanitation applications. The pumps can empty a typical 30-gallon holding tank in less than 3 minutes, delivering the quick performance that mariners need when pumping out waste tanks. The four-bladed chopper reduces clogging by grinding waste materials to a uniform consistency, ensuring smooth transfer through discharge hoses without blockages that can plague inferior pump designs.

The 18590 Series: Jabsco's Workhorse Solution

The Jabsco 18590 series DC macerator pump unit is the ideal solution for emptying marine holding tanks when not in a discharge restricted area. Available in both 12V and 24V configurations, these pumps showcase Jabsco's engineering priorities: robust construction paired with protective features. A triple sealed motor prevents both internal and external motor corrosion, addressing the harsh marine environment where saltwater exposure can quickly degrade lesser equipment. The heavy duty 4-blade chopper and fully sealed motor with dry-run protection device work together to extend pump lifespan while preventing damage from accidental operation without fluid.

Designed for Marine Demands

Jabsco's macerator pumps incorporate practical features that reflect real-world marine usage patterns. The duty cycle of the pump is 15 minutes continuous, which means a 180-gallon tank can be emptied in a single operation, providing sufficient capacity for extended cruising without mid-operation cooling breaks. A durable powder coating prevents corrosion from occurring both internally and externally, ensuring that these pumps maintain their reliability season after season in challenging marine conditions.

Whether you're outfitting a new vessel, upgrading an aging sanitation system, or replacing a failed pump, Jabsco's macerator and waste pump solutions deliver the combination of throughput, durability, and protective engineering features that marine applications demand. Their widespread adoption across recreational and commercial marine sectors speaks to their proven track record in one of boating's most critical systems.
