Wilo-PB
Safe and stable pressure boosting for the residential environment.
Safe and stable pressure boosting for the residential environment.
The Wilo-PB is a non-self-priming, single-stage centrifugal pump for automatic water supply and pressure boosting. It is suitable for the descending installation of roof-mounted water tanks (e.g. elevated tanks) to the extraction points of the water supply below in semi-detached/detached houses. It is the ideal pump for low or fluctuating water pressure within public water supply networks. Thanks to automatic mode, it always ensures stable water pressure.
