When designing a pumping system for industrial, commercial, or municipal applications, choosing between split case and end suction pumps can significantly impact system performance, maintenance requirements, and long-term operational costs. In this comprehensive guide, we'll explore the key differences between these two pump types, helping you make an informed decision for your specific needs.

Split case pumps, also known as horizontally split case pumps, feature a unique design where the pump casing is divided horizontally into two parts. This distinctive construction allows for easy access to internal components without disturbing the connected piping or drive system. The impeller is typically mounted between bearing assemblies on both sides, providing excellent support and stability during operation. Learn more split case pump
End suction pumps utilize a simpler design where fluid enters through a single inlet at the pump's end and exits through a discharge connection typically positioned at the top of the casing. These pumps feature an overhung impeller design, meaning the impeller is mounted on a shaft supported by bearings on only one side. Learn more end suction pump
