Everybody likes a quiet pump — one that just does its job and doesn’t break down often. But a noisy pump raises concern. Although the noise is often attributed to cavitation, not every noisy pump is suffering from this problem. Failing bearings, flow turbulence, recirculation, and even a machine’s mechanical or electrical geometry can also generate noise — any of which may be a more immediate problem than long-term damage from cavitation.
Cavitation erodes the
