CH 4-60 B (50 Hz) - Centrifugal multistage boostamatic pump


The CH 4 Boostamatic range of centrifugal multistage pumps has been designed to provide a pressurised water supply from a break tank in either a positive or negative head application, as it does not rely on gravity flow to activate.

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


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

* The maximum pressure that can be applied to the pump under any installation conditions.

** A stored water temperature of 60 °C is considered sufficient to meet all normal requirements and will minimise deposition of scale in hard water areas.

*** A suction lift of up to 4.6 metres can be achieved if a footvalve and strainer is used.
