CH 4-50 B (50 Hz) - Centrifugal Multistage Boostamatic Pump

Previous Products

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.

Application
