PENTAIR SHURFLO 5059-3611-D011 12V DC Bypass 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 5059-3611-D011 Bypass Diaphragm Pump is designed for fluid transfer systems requiring stable flow and resistance to agricultural chemicals, delivering up to 5.3 GPM. It uses a Santoprene diaphragm and Viton valves, and includes 1/2 inch NPSM ports to support compatibility with standard fittings while maintaining service life under repeated operation. The unit features an internal bypass and a 90 PSI pressure switch to regulate system pressure and limit cycling during variable demand conditions. It is self-priming up to 8 feet, supporting installation in tank-fed or remote setups, and operates with a sealed 12V DC motor suited for mobile and outdoor environments. The mounting footprint matches standard SHURFLO configurations, allowing replacement or system upgrades without modification. Applicable for agricultural spraying, irrigation transfer, marine washdown, and RV water systems requiring higher flow capacity.
