What should I do if my hydraulic pump is making unusual noise?

Stop the equipment and check the suction line, strainer, and reservoir fluid level first, since unusual noise often indicates cavitation from fluid starvation rather than a purely mechanical pump fault. Continuing to run a cavitating pump causes cumulative, irreversible internal pitting damage, so addressing it quickly matters. If the noise persists after checking these basics, a technician should inspect the pump internally. Sparkline Group offers diagnostic support for exactly this kind of noise complaint across UAE sites.
