CH 9-14 FL (50 Hz) - Centrifugal single stage automatic flow switch pump


The CH Automatic Flow Switch range of centrifugal pumps are ideal for the pressurisation of water to outlets in a positive head application, where a gravity flow of approx. 1 l/min already exists.


  • The range is suitable for commercial or domestic use, pumping hot or cold water
