A lock washer is a small but essential hardware component that sits beneath a nut or bolt head to resist loosening caused by vibration and dynamic loads. On a centrifugal pump like the QPT405SLT, where continuous motor and impeller vibration are part of normal operation, lock washers play a critical role in keeping fastened assemblies secure. When a lock washer fails, flattens, or is omitted during reassembly, fasteners can back out gradually, leading to leaks, misalignment, or component separation.
