Flojet D3131H5011AR - Flojet Duplex II Demand Pump

Flojet D3131H5011AR - Flojet Duplex II Demand Pump

The Flojet D3131H5011AR Duplex II Demand Pump is an advanced 12V DC diaphragm pump designed for intermittent duty applications. With a powerful output of up to 5.3 liters per minute (1.2 GPM), it is perfect for fluid handling tasks such as water transfer, spraying, and fluid circulation. The self-priming capability, allowing vertical lifts of up to 2.4 meters, makes it versatile and reliable for a wide range of applications. Featuring a durable Duplex diaphragm design, the pump supports extended dry-running capabilities, ensuring its longevity and reliable performance. The pressure switch automatically activates at 2.1 bar (40 psi) and deactivates at 4.2 bar (60 psi), maintaining consistent pressure levels. Constructed with Santoprene diaphragms and EPDM valves, the pump is built for durability and chemical resistance. This pump is ideal for industrial, agricultural, and residential systems where consistent fluid transfer is required. Easy to install with 9.5mm (3/8") NPT connections, the Flojet D3131H5011AR ensures efficient operation and long-lasting performance.
