Shurflo 4.0 Pro Blaster Washdown Pump - 12V DC, 4.0 GPM, 45 PSI Marine Washdown Pump

The Shurflo 4.0 Pro Blaster Washdown Pump is a 12 volt DC marine washdown pump built for tough onboard cleaning jobs like fish box rinsing, scaling, and anchor chain washdown. This self-priming pump primes up to 6 feet of lift, can run dry without damage, and is designed to deliver quiet, smooth operation without overheating during extended use.

Inside the pump is a 4-chamber diaphragm design that produces a steady, consistent spray pattern at 4.0 GPM with a 45 PSI shut-off pressure. The motor uses a seamless, electro-coated shell to resist corrosion in harsh marine environments, and the pressure switch is fully sealed against water intrusion. The pump is ignition protected and includes thermal overload protection with automatic restart, so it shuts down safely if it overheats and comes back online once it cools.

Every pump ships complete and ready to plumb in: it includes a Blaster spray nozzle plus fittings sized to accept 3/4 inch I.D. Hose, so it drops into most washdown setups without hunting for extra parts. The compact housing measures 7.3 inches by 5.0 inches by 4.6 inches, making it easy to mount in tight bilge or deck compartments on fishing boats, center consoles, cruisers, and pontoons.
