Since these pum pcurv es usually apply to a particular impeller an dpump design, different manufacturers may sho wslightly different performance for the same type andsi ze of pump. Therefore, several manufacturers pump c urves should be checked to esta

42、blish arealistic and cost effective criteria for the pum psele ction. Figure 3-3 shows three types of pum phe ad capacity (performance) curves; a “norma lrisin g“ curve, a “drooping“ curve and a “steepl yrising“ curve.For pumps in a typical water supply an d distributionsystem, only pumps with “norm

Pumpswith these characteristics will perform well i npara llel operation and will have relatively smal lcapacity change with pres sure changes. In addition,the b rake-horse power curve will be relatively flat,which will minimize the
