CH 4-30 (50 Hz) - Centrifugal multistage pump

CH

The CH 4 range of centrifugal multistage pumps are built to provide a high quality and reliable solution for applications that require high flow rates of up to 160 l/min and heads up to 62 metres.

The range includes 4 base pumps suitable for independent switching.

Application

  • The CH 4 range of pumps are the ideal base unit for pressure boosting sets or for applications where long pipe runs or high heads may be involved
  • 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.

*** With footvalve fitted.
Although these pumps are self priming we recommend a footvalve/strainer is used if a suction lift is required.
