Johnson Pump Aqua Jet 5.2 GPM Washdown Pump Kit with Hose – 12V | MPN: 64534

Keep your deck, cockpit, and anchor clean with the Johnson Pump Aqua Jet 5.2 GPM Washdown Pump Kit (Part Number: 64534). Engineered for high-performance marine cleaning, this complete 12-volt system delivers powerful 70 PSI water pressure to effortlessly blast away salt spray, mud, fish scale, and grime from powerboats, center consoles, and yachts.

At the core of the kit is the Aqua Jet WD 5.2 GPM five-chamber diaphragm pump. Its 5-chamber design provides smooth, quiet, and pulsation-free water delivery compared to traditional 3-chamber or 4-chamber pumps. Equipped with an integrated pressure switch, the pump automatically turns on when you pull the spray nozzle trigger and shuts off when released, saving power and extending pump life.

Key Features & Benefits

  • High-Flow 5.2 GPM Output: Delivers up to 5.2 gallons per minute (20 liters per minute) for rapid deck rinsing and anchor cleaning.

  • 70 PSI High-Pressure Spray: Industry-leading pressure rating provides intense blasting force for stubborn mud and fish blood.

  • 5-Chamber Diaphragm Technology: Eliminates pressure pulsations and reduces mechanical noise for ultra-quiet operation.

  • Automatic Pressure Switch: Integrated switch starts and stops the pump on demand as the spray nozzle trigger is operated.

  • Self-Priming & Dry-Running Protection: Self-primes up to 6.6 feet (2 meters) and tolerates running dry without immediate damage to internal diaphragms.

  • Complete Turnkey Kit: Comes fully equipped with a 25-foot heavy-duty UV-resistant coiled hose, spray pistol nozzle, bulkhead connector with shutoff valve, and a 40-mesh PUMProtector inlet strainer.

  • Salt & Freshwater Compatible: Built with corrosion-resistant seals, a sealed motor housing, and heavy-duty ball bearings for harsh marine environments.

Happy Customer

First I would like to thank the team at anchor express for expediting my order so that I had the pump mounted on board and serviceable before a weekend trip. The part was back ordered and it did not look as though it would make it in time. A few hours later I received notice it would be at my house the next day. Great customer service and recovery. The pump works great with nozzle pressure that exceeded my expectation. Very quiet unit. It did not align with the previous pumps mounting holes like I had hoped but two of them aligned perfectly allowing me to get underway so be mindful of that if you purchase this unit. You may have to relocate it to another spot, plug holes etc... Thanks Anchor express for making this purchase a good experience!
