Cavitation, erosion, and corrosion are the three most common causes of impeller failure. Cavitation is a significant risk for any centrifugal pump. Cavitation is most commonly observed on the pump impeller and is caused by a pressure difference on the pump body or the impeller. An impeller is a component of a pump or compressor that rotates at high speeds and acts as a propeller to increase the pressure and flow rate. The impeller transfers energy to the fluid as it passes through the pump, increasing the fluid's velocity at the pump's discharge outlet. The impeller is nothing more than a series of rubber vanes molded around a hub. The vanes are flexible, and the hub rotates on an eccentric within the stainless steel-lined pump housing.
