Stenner Econ FX Series Fixed Rate Pump | E20FXB
The Stenner E20FXB is a streamlined, fixed-rate peristaltic pump designed for reliable chemical dosing in low-pressure water systems. This model is engineered to provide a consistent output of 24.8 Gallons Per Day (GPD), offering a dependable "set-and-forget" solution for applications where a stable, unchanging flow rate is required.
Operating at pressures up to 25 PSI, the E20FXB is a popular choice for light-duty commercial and residential projects, including swimming pool sanitation, cooling tower treatment, and irrigation. Its simplicity is its strength; with no manual speed adjustments to manage, it integrates seamlessly into automated systems that use timers or controllers to trigger dosing cycles.
