PH 45 ES B (50 Hz) - Peripheral horizontal end suction boostamatic pump


The PH ES Boostamatic range of peripheral pressure switch pumps are designed to provide a pressurised water supply from a break tank in either positive or negative head applications and do not require a gravity flow of water to activate.


  • All models are ideal for automated pressurisation of hot or cold water services in a single dwelling, or commercial premises
