Rule 56D Non-Automatic 4000 GPH Bilge Pump - 12V DC, 2 Inch Hose Barb Discharge

The Rule 56D is a non-automatic 4000 GPH (15140 LPH) bilge pump built for the toughest bilge-clearing applications, delivering the highest pumping capacity available for a pump of its size. Rule bilge pumps are used by yachtsmen and fishermen worldwide, and the 56D carries forward Rule's core design advantages in a compact, long-life motor package. It can run dry for short periods without burning out, and a snap-lock strainer base makes cleaning quick and tool-free. Back flow prevention reduces the amount of water left sitting in the bilge after each cycle, cutting down on odor and keeping the bilge cleaner between pump-outs. Hidden air vents within the pump body help prevent air locking in demanding plumbing runs and support reliable check valve operation. A built-in thermal cut-off protects both the pump and the vessel's electrical system, while threaded discharge simplifies installation and future maintenance. The pump is completely submersible, rust and corrosion protected, ignition protected, and runs silently. As a non-automatic (manual) pump, the 56D is designed to be paired with a separate switch for automatic operation and works with Rule float switches 37A and 40A, panel switches 41, 43, 45, and 49, and the Model 279 replacement strainer.
