Flojet 12v, 5 GPM Demand Pump


The FloJet "Quad" Water System Pumps is a 12 volt DC, intermittent duty automatic water system pump. This pump is well suited for use with a holding tank water system, as may be found in a boat, RV or remote cabin. Flojet's Quad Pump series provides high volume water flow with reduced pump cycling, thanks to the four chamber diaphragm and internal bypass. The 4300 models are designed to run on water systems with no accumulator tank.


Quad Pumps are self-priming, and can run dry without damage. The internal bypass feature allows excess water to recirculate inside the pump, eliminating the need for an accumulator tank. They're easy to install, service and winterize with Quad snap-in port fittings.


This 12 volt DC pump has a maximum flow of 4.9 GPM, a maximum PSI of 45 pounds and will start and stop on demand.
