Jabsco Diaphragm Shower & Bilge Pump 50880-1000, 12V 4.2 GPM Self-Priming Dry-Run

The Jabsco Diaphragm Shower & Bilge Pump (50880-1000) is a compact, self-priming 12V diaphragm pump built for flexible installation anywhere water needs to be moved out of a boat, whether draining a shower sump or clearing bilge water. Its simple, filter-less design means there is no strainer to clean or clog, and the pump can be mounted above the water line since it is self-priming from dry up to 10 feet of vertical lift. The permanent magnet motor drives the diaphragm mechanism to deliver a nominal open-flow rate of 4.2 gallons per minute, drawing 8 amps on a 10 amp fuse. Unlike centrifugal pumps that can be damaged by running dry, this diaphragm pump is built for extended dry-running without harm, making it forgiving in low-water or intermittent-use situations such as shower sumps. The plastic body resists corrosion in the marine environment, and the pump connects using a 3/4 inch hose barb port for straightforward plumbing. The Jabsco 50880-1000 is built to recognized marine standards, meeting ISO 8846 MARINE and USCG regulations for ignition protection, ISO 8849 MARINE Bilge Pump Standard, and ISO 15083 specification requirements. Its compact footprint and multi-position mounting flexibility make it suitable for tight installation spaces where a traditional bilge pump will not fit.
