Booster Pumps are used to further boost the pressure in a system. It may be end suction, in-line circulator, horizontal split case, or a single or multi stage vertical turbine pump. Booster pumps are used in applications where the normal system pressure is low and needs to be increased. These pumps are specifically designed for boosting water pressure in municipal, well water systems, rain water collection systems, and garden and irrigation applications. Booster Pumps are usually located near the source of water somewhere between the building meter and where the water main enters the building. The maximum boost pressure for a pump is in addition to your existing system pressure.
