Kelco F27 Time Delay Flow Switch is a robust, high-performance solution for protecting pressure systems and bore pumps from dry run damage. Designed and manufactured in Australia, this advanced paddle flow switch integrates built-in digital timers to ensure reliable pump operation, even in challenging conditions.

The F27 ensures smooth pump function by overriding the off state during startup, allowing initial flow establishment while preventing dry run scenarios. The adjustable run-on timer maintains operation during minor flow interruptions, ideal for pressurising systems and handling low-yield bores.

Suitable for 25mm pipes and larger, the F27 is easy to install in straight discharge sections. Its magnetic paddle suspension provides frictionless performance, while brown-out and voltage surge protection ensure durability. For industrial, rural, and irrigation applications, the Kelco F27 Flow Switch is the ultimate safeguard for your pumping systems.
