What is a common symptom of a damaged impeller in a centrifugal pump?

A common symptom of a damaged impeller in a centrifugal pump is reduced capacity. The impeller is a critical component in a centrifugal pump that helps to convert rotational energy from the motor into kinetic energy in the fluid being pumped. When the impeller is damaged, often because of wear, cavitation, or other mechanical issues, its ability to effectively move fluid can be compromised.

This reduced capacity manifests as a decrease in the flow rate, meaning the pump cannot push as much fluid through the system as it should under normal operating conditions. This drop in performance can lead to inefficiencies in the overall system, decreased output, and potential operational issues that could affect downstream processes.

Understanding this is crucial for maintenance and troubleshooting. By identifying reduced capacity as a symptom of a damaged impeller, technicians can take timely action to inspect, repair, or replace the impeller, ensuring the pump operates efficiently and effectively.
