2020-6-2u2002·u2002Pump noise caused by cavitation: Cavitation is a common pump problem that is characterised by a high pitched whining sound or, in extreme conditions, a severe rattling sound. This sound is caused by a condition in which a drop in fluid pressure causes cavities to form in the fluid, which rapidly implode (hundreds or thousands of times every ...
Get PriceThe whining sound may be augmented by a sound similar to marbles or gravel rattling around inside the pump. If you can see the oil in the reservoir, you may see foaming. Air in the oil can cause a system to perform sluggishly and can damage the pump and other system components. Aeration can be caused by:
Get Price2020-10-19u2002·u2002A 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 Price2010-8-5u2002·u2002Pump Cavitation A pump that is cavitating makes a steady, high-pitched whining sound. Since the sound is steady and does not reflect changes in the movement of the machine, it is often confused with bearing wear in the pump. Often a pump is replaced unnecessarily because it is cavitating.
Get PriceI purchased a 2005 Kubota M105S with 700 hrs on it. The hydraulic system makes a whining noise that sounds to me like it has a restriction somewhere. It sounds like maybe a relief valve is lifting. Not sure! The noise gets louder anytime you activate the hydraulic system - - …

Get Price2020-8-17u2002·u2002Check the fluid level in the reservoir, and if low, fill to the correct level. In some systems, air can enter the pump through its shaft seal. Check the condition of the pump shaft seal and if it is leaking, replace it. Cavitation occurs when the volume of fluid demanded by any part of a hydraulic circuit exceeds the volume of fluid being supplied.
Get Pricethanks. if the sound is more of a high pithced ticking sound, it points to cavitation, or starvation of the pump. and yes draining the hydraulic oil and checking the sucktion screen is a good idea. there might be junk caught in there. and also check the oil comming out for obvious particles.
