Johnson Pumps

<h3>About Johnson Pumps</h3><p>For more than eight decades, <strong>Johnson Pumps</strong> has been synonymous with dependable marine pumping solutions. As part of the <strong>SPX FLOW</strong> family, Johnson Pump engineers products that serve everyone from weekend recreational boaters to demanding commercial vessel operators — making it one of the most trusted names on the water worldwide.</p><p>What sets Johnson Pump apart is a philosophy rooted in marine-specific design. Every pump in the lineup is built with corrosion-resistant materials, sealed components, and protection engineered against debris damage — the kind of real-world threats that cause lesser pumps to fail at critical moments. A modular design approach further simplifies maintenance and reduces the inventory of spare parts a boater needs to carry.</p><h3>Bilge Pumps</h3><p>At the core of the Johnson Pump catalog are its <a href="/11265-johnson-pumps">submersible and automatic bilge pumps</a>. Available in cartridge, heavy-duty, and Ultima series configurations, these pumps range from compact 500 GPH units suited for smaller vessels to high-capacity 4,000 GPH workhorses built for offshore and commercial duty. Automatic models feature reliable float switches and electromagnetic activation that respond the moment water is detected — providing the kind of fail-safe performance that serious boaters depend on.</p><h3>Washdown Pumps</h3><p>The <strong>Aqua Jet</strong> series represents Johnson Pump's flagship line of <a href="/11265-johnson-pumps">washdown and water pressure pumps</a>. Delivering up to 5.2 GPM at pressures up to five bar, these quiet, pulsation-free systems handle everything from deck washing on small cruisers to raw-water supply on larger commercial boats. The Aqua Jet lineup also includes combination livewell and washdown kits that simplify plumbing by sharing a single water intake.</p><h3>Livewell &amp; Aerator Pumps</h3><p>Fishing enthusiasts trust Johnson Pump's <a href="/11265-johnson-pumps">livewell and aerator pump systems</a> to keep bait and catch alive throughout the day. The Pro Series aerator pumps and dedicated baitwell models provide consistent water circulation and oxygenation, with designs optimized for low power draw so they won't tax your boat's battery bank on long days on the water.</p><h3>Impellers &amp; Replacement Parts</h3><p>A key strength of the Johnson Pump brand is the depth of its genuine <a href="/11265-johnson-pumps">impeller and spare parts</a> offering. Johnson's flexible impellers — including the proprietary MC97 compound — are engineered for maximum flow, long service life, and resistance to swelling. Using genuine OEM impellers ensures compatibility with the tight tolerances of Johnson pump housings and meets the quality standards required by engine manufacturers. Replacement motor cartridges for cartridge-style bilge and livewell pumps make field servicing fast and straightforward.</p><h3>Circulation &amp; Engine Cooling Pumps</h3><p>Beyond bilge and deck systems, Johnson Pump produces a range of <a href="/11265-johnson-pumps">circulation and engine cooling pumps</a> for both raw-water and closed-loop applications. The CM series of magnetically driven circulation pumps — available in brush and brushless motor variants — deliver smooth, quiet operation ideal for heating loops, bait-chilling systems, and other onboard circulation duties.</p><h3>Why Choose Johnson Pumps?</h3><ul style="list-style:disc"><li>Over 80 years of dedicated marine pump engineering experience</li><li>Part of the global SPX FLOW group, with ISO 9001-certified manufacturing</li><li>Corrosion-resistant, marine-grade materials built for fresh and saltwater environments</li><li>Low noise, low power draw, and minimal maintenance design philosophy</li><li>Comprehensive genuine spare parts and global service network support</li><li>Trusted by OEM boat builders and aftermarket customers worldwide</li></ul>
