Hydraulically, the flow and head range of the pump positions it between the WXB and WCC models. Critical portions of its massive forged barrel are analyzed by finite element analysis to withstand high stresses of each application. The center diffuser stack is designed using the latest computational fluid dynamics technology to ensure exceptional efficiency and ultralow radial loads.
