PENTAIR SHURFLO 5059-1311-D011 12 VDC Automatic Demand Diaphragm Pump, 5.3 GPM, 90 PSI, 1/2" NPSM Port, Self Priming 8 ft, Chemical Resistant Water Pump for Spraying, Transfer, Industrial Use

The PENTAIR SHURFLO 5059-1311-D011 automatic demand diaphragm pump delivers up to 5.3 GPM with a maximum pressure rating of 90 PSI. It is designed for fluid transfer applications including agricultural spraying, mobile water systems, irrigation, and general industrial use, where consistent flow and pressure are required. The pump is constructed with a Santoprene diaphragm and Viton valves to support compatibility with a range of fluids and extended service life. An integrated pressure switch set at 60 PSI automatically controls pump operation and stops the unit under closed flow conditions to reduce the risk of damage during dead heading. It is equipped with 1/2 inch NPSM ports for standard hose and fitting connections. It features a sealed 12V motor and is self priming up to 8 feet. The pump shares the same mounting footprint as other SHURFLO models, allowing direct replacement or upgrade without modification to existing installations.
