1. Introduction
Centrifugal pumps, compressors, and blowers utilize various impeller designs that are an essential component for bulk transport of fluids. Typically, a motor is used to spin a shaft that is connected to a housed impeller, which draws fluid in along a rotating axis. The fluid is accelerated and whirled radially and tangentially outward through the impeller vanes, where it exits through a casing designed to decelerate the fluid velocity and increase fluid pressure. Centrifugal pumps are susceptible to various modes of impeller failure including but not limited to intergranular corrosion, erosion, cavitation, material defects, as there are a number of documented case studies in the literature [1–4]. Respiratory care devices utilize centrifugal blowers for oxygen transport, which controls pressure and flow measurements for output optimization of the centrifugal blower and impeller velocity [5]. While there have been a number of failure analysis case studies related to centrifugal pumps and compressors in other industries utilizing alloy impellers, no case studies have focused on polymer based centrifugal impellers, and their associated modes of failure. Non-experimental fractographic analysis of equipment used in service allows for the understanding and further prevention of failure modes to ultimately extend the lifespan of such devices.
