This article is a follow up to the article, "Selecting Fire Pumps for ESFR Sprinkler Applications," published in PME in March 2002. The original article outlined the design challenges associated with widely fluctuating residual and static pressures experienced in ESFR sprinkler systems. The article further offered a number of ways to remedy this problem by applying alternative fire pump system designs.
