Shurflo Fresh Water Pump, 12V DC, 4 GPM 4048-153-e75

AMERICAN MOTORHOME RV FRESH WATER PUMP, 12V DC, 4 GPM 4048-153-E75 The SHURFLO 4048 High Flow Revolution pump is a heavy-duty 12V DC solution designed for multi-fixture RV and marine fresh water systems. This powerful four-chamber diaphragm pump delivers a smooth, high-powered flow of 4.0 gallons per minute (GPM) at pressures up to 55 PSI, making it an ideal upgrade for those requiring "at-home" water performance while on the move. Equipped with proprietary Flow Reaction Technology, this pump utilizes a unique one-piece diaphragm and internal bypass system to significantly reduce rapid cycling and water hammering. These advanced features allow the pump to operate quietly across various flow conditions and eliminate the need for an external accumulator tank in most installations. Engineered for long-term reliability, the 4048 series is self-priming up to 6 vertical feet and can safely run dry without sustaining damage. The unit is thermally protected with an automatic restart feature and is constructed with a durable polypropylene housing, EPDM valves, and a Santoprene diaphragm to withstand demanding environments.
