Flow Switch for Direct Switching of Pump

Manufacturer's part number :


Manufacturer UK_CYNERGY3_SI.png


Description :

The FSP10 is designed for directly controlling an electric pump that is providing increased pressure or flow within water systems that are gravity fed from storage tanks. The device has to be fitted in the pipe above the pump.

The FSP10 starts up the pump when the flow rate through the device exceeds 0.6 l/min, so giving an increased flow and pressure, dependant on the pump capacity. A flow of less than 0.6 l/min , or 3.0 l/min depending on version, whether due to a lack of supply (e.g. tank empty) or to a decrease in demand(e.g. tap closing), will turn the pump off again.
