The Welflo WFSM405AX smart centrifugal pump features a LED display panel that allows the user to both set and monitor the water pressure and pump working condition - This makes for an indispensable tool for troubleshooting water pressure-related problems allowing the user to quickly diagnose between a malfunctioning pump or clogged plumbings.

The Welflo WFSM405AX displaces the older Welflo HQSM405A and apart from the LED display and streamlined model naming convention, you still get the same legendary Welflo consistent water pressure coupled with legendary reliability, backed by a 36-months warranty!
