Keeping the noise levels down in the workplace is not only vital for the morale and performance of your staff, but in many cases there are also safety regulations and restrictions to consider. Given the power and the size of the machinery involved in hydraulic systems (hydraulic pumps, hydraulic cylinders, hydraulic valves and so on), noise levels are clearly something that should not be neglected.

Generally speaking the hydraulic pump is what causes the most noise out of all hydraulic parts and the three main sources of noise are: structure-borne, fluid-borne and air-borne.

When it comes to fluid-borne type of noise, it’s difficult to completely cut out the noise caused during operation, but it can be significantly reduced by installing a hydraulic pump silencer.

Structure-borne noise comes about due to vibrations between the hydraulic pump and its corresponding prime mover. This can usually be reduced by cutting out sound bridges relaying between the power unit and the tank and hydraulic valves.

Finally, air-borne noise can be reduced considerably by mounting the hydraulic pump inside of the system’s tank, though the knock-on effect of such a layout is that the tank itself becomes less accessible.
