Get Price2020-10-19 · A hydraulic pump might get noisy if one of its parts or connections has a problem. A faulty or failing pressure control, bearing, valve, seal, or coupling can make a noise you haven't heard before. For example, if a relief valve stops working correctly and opens up permanently or too often, then the valve might make hissing sounds.
Get Price2019-8-21 · Something else — not mentioned in the catalog — is contributing to the increase in noise level. The problem is that any slight noise generated by the pump is amplified throughout the structure of the hydraulic equipment. Lab tests show that pump noise levels are increased by 2 to 3 dB A just by adding 12 ft of outlet and return lines. These lines do not generate noise - instead they radiate noise when they respond to pulsations or vibrations generated by the pump.
