Johnson Pump Cartridge Aerator 750 GPH Straight Intake - 12V

The Johnson Pump Cartridge Aerator 750 GPH Straight Intake 12V is a compact, reliable circulation pump engineered for marine environments where consistent water movement and aeration are critical. With a 750 gallons-per-hour capacity and straight intake configuration, this pump delivers dependable performance in confined spaces aboard vessels, in live wells, and across marine support operations where compact footprint and ease of installation directly impact operational efficiency.

The 12V specification aligns with standard marine electrical architecture found on military vessels, patrol boats, and offshore platforms. Johnson Pump's cartridge design prioritizes accessibility—the motor cartridge can be swapped without removing the entire pump body, reducing maintenance downtime in field conditions. The Dura-Port discharge port simplifies hose connections and reduces leak points common in high-vibration marine environments. At 1.1 pounds and measuring 8 x 3 x 12 inches, the unit fits into cramped engine compartments and bilge spaces where larger centrifugal pumps would be impractical.

This model serves operators managing live-water systems, circulation cooling loops, and aeration duties aboard escort vessels, research platforms, and tactical watercraft. The straight intake design (versus 90-degree alternatives) accommodates installations where inlet and outlet must align vertically or in tight lateral configurations. Operators requiring flexible intake angles should evaluate the 90-degree variant; the straight configuration excels when space and installation angle are already determined.

Johnson Pump produces cartridge aerators across 500, 750, 1000, and 1250 GPH capacity increments, allowing selection matched to specific system demand. The 750 GPH rating represents a middle-ground choice for small-to-mid-sized live wells, bait systems, and circulation applications. Verify intake and discharge diameter against your existing plumbing before ordering to ensure seamless integration.
