The Johnson Pump 4000 Series Heavy Duty Bilge Pump is built for high performance under commercial and recreational demands that would wear out a lighter-duty pump fast, with a liquid-cooled, 12-pole motor and double ball bearings for extended service life.
A mechanical seal design keeps water out of the motor compartment, and a carefully engineered impeller is tested to maximize both head and flow rather than sacrificing one for the other.
It discharges through a 1-1/2 inch port and runs on 12V, built as the serious option for a boat that needs to move a genuinely large volume of water fast. See what else we carry in bilge pumps.
