A quiet pump serves as a good industrial equipment for many. Moreover, an industrial pump that does not elicit any noise means doing its job at its very best. However, the concern goes on the moment the pump becomes noisy.

Yet, the noise may be linked to cavitation but it doesn’t mean that every industrial pump that is noisy is having the same problem. Furthermore, the noise of an industrial pump may also come from bearing failure, recirculation, flow turbulence, or electrical geometry. 

These immediate industrial pump issues may be an immediate one compared to cavitation. Moreover, at some point, it becomes music to the ears.

Basically, cavitation damages the suction eye of the impeller without giving effect on the surface. 

How to address the sounding noise of an industrial pump like what grabe does

Generally, the noise from the industrial pump that comes from cavitation should be inspected to verify if it is really the source of the noise. Like grabe, here are the basic steps in order to address potential causes of the sounding noise. 

Eliminate the bearing noise 

Typically, this is easy to identify. Simply listen to the volute and bearing housing of the pump. Once the sounding noise is louder compared to the volute than the bearing, rule out the bearing noise as the source of the issue

This can be determined by using an ultrasonic listening device. However, you can also use a mechanic’s stethoscope if device availability is your concern. 

Look for recirculation

Generally, you may know if the cause is more on recirculation once the alteration of the suction head affects the noise a little. This will eventually lead to a discharge flow restriction. Moreover, the cause of this is the obstruction of the discharge valve.

However, determining the flow rate under a closed system that does not contain flow rate instrumentation may be difficult. You’ll only need to have a portable flow meter attached to the piping. This will generally offer accurate information. Yet, this may be costly.

Identify if the sounding noise comes from mechanical or electrical geometry

You may easily know if it is a mechanical or electrical concern. Once the noise of the pump comes from changing of the suction head or the discharge flow, it is usually a mechanical issue.
