Jabsco 12V Sealed Self-Priming Macerator Pump (18590-2092)

The Jabsco 18590-2092 Sealed Macerator Pump is a 12V DC, self-priming pump with run-dry protection for marine holding-tank, fish-box, and livewell evacuation. Its stainless steel cutter reduces particle size before discharge, while self-priming capability supports installations where gravity drainage is not practical.

Key features

• Self-priming to 5 feet: Suitable for evacuation applications that require suction lift.
• Run-dry protection: Incorporated into the sealed macerator pump design.
• Four-blade stainless steel cutter: Reduces particles to a maximum size of 1/8 inch.
• Nitrile impeller: Uses Jabsco nitrile compound.
• Lip-type seal: Part of the pump's sealing construction.
• Duty cycle: Up to 15 minutes of continuous operation.

Applications and care

For emptying marine holding tanks where discharge is permitted, as well as fish boxes and livewells. A typical 30-gallon (115-liter) holding tank can be emptied in less than three minutes; actual evacuation time depends on installation and operating conditions.

Do not use for holding-tank discharge in restricted areas. Flush holding tanks with several gallons of water after each pump-out to help reduce sediment buildup and potential blockages. Follow the owner's manual for installation, operation, and maintenance.
