Flojet D3131V1311AR - Flojet Duplex II Bypass Pump

The Flojet D3131V1311AR Duplex II Bypass Pump is a high-performance, self-priming diaphragm pump designed to provide reliable fluid transfer in various applications. It operates on a 12V DC power supply and is capable of delivering up to 5.3 liters per minute (1.2 GPM), making it ideal for water filtration, irrigation, and other fluid handling systems that require intermittent-duty operation. With a maximum recommended total head of 30 meters (98.4 feet), this pump ensures consistent performance, even in demanding environments. The duplex diaphragm design allows for extended dry running and enhanced durability, ensuring long-lasting reliability.

Equipped with Viton diaphragms and valves, the Flojet D3131V1311AR is resistant to harsh chemicals, high temperatures, and wear, making it suitable for a wide range of industrial and residential applications. It features a built-in internal bypass set at 3.5 bar (50 psi), which helps to maintain stable system pressure while protecting against over-pressurization. The pump is designed to self-prime up to 2.4 meters (7.9 feet), allowing for flexible installation options. The unit’s compact design, combined with low power consumption, makes it both energy-efficient and easy to install.
