Buildings of all types and sizes use pumps for  re protection, heating, cooling and for domestic water distribution. 

While these pumps do not generally represent a large fraction of the total building cost or energy budget, careful selection of the pump type and size will reduce both the  rst cost of the building, and the cost of operating the building over the years. More importantly, proper selection of the pumps will make the building more valuable by providing reliable, sustainable service at low cost. This manual will discuss the operation, selection, and installation of centrifugal pumps, the most widely used type of pump in building service.
