The Flojet D3135B1311AR is a self-priming duplex diaphragm bypass pump for 12V DC systems, designed for fluid transfer with extended dry-running capability. It delivers up to 7.5 L/min (1.9 GPM), provides a self-priming lift up to 2.4 m, and has a maximum recommended total head of 30 m. The internal bypass is set to 3.5 bar (50 psi), with 3/8 inch (9.5 mm) NPT connections; it uses nitrile diaphragms and valves with EPDM O-rings and a polypropylene housing, and is specified for intermittent duty operation.

Flojet Duplex II Self-Priming Diaphragm Bypass Pump (12V DC)
The Flojet D3135B1311AR is a Duplex II series self-priming diaphragm pump built for 12V DC installations where reliable transfer, dry-running tolerance, and pressure control are required. Its duplex diaphragm design supports extended dry running, while the integrated bypass helps protect the system from excessive pressure build-up.
Features
- Duplex diaphragm design for extended dry running
- Self-priming capability up to 2.4 m vertical lift
- Integrated internal bypass set at 3.5 bar (50 psi) for pressure control
- Intermittent duty design
- Nitrile diaphragms and valves for chemical and abrasion resistance
