The Wilo-PB is a non self-priming, single-stage centrifugal pump for automatic water supply/pressure boosting. It is a downward installation for the supply from a tank (e.g. elevated tank) on the rooftop to extraction points located beneath for single-family/two-family houses. It is the ideal pump in case of low or fluctuating water pressure in the public distribution network and it guarantees a stable water pressure due to an automatic operation.
