There are a lot of components in a hydraulic system, and the pump is the one that is most subject to wear. It’s also the component that is most likely to cause gradual failure in your system, and in some cases, this can occur suddenly, so your pump needs to be inspected to prevent such problems.
Increased noise, difficulty to develop full output, decreased speed of cylinders or hydraulic motors and increased heat are all signs of pump trouble, as is erratic operation of cylinders. These are indications that your hydraulic pump needs to be replaced, so it’s a must that you address this problem. Proper maintenance will allow most hydraulic pumps to operate smoothly for years, but the pressure inside the device will eventually lead to failures, and the following symptoms will tell you that it’s time for a replacement:
Strange Sounds
Hydraulic pumps should work quietly because they are specifically designed this way. As parts wear down, however, you may start to notice strange sounds, and this will also happen whenever the seal starts to deteriorate. If you hear banging and knocking sounds, it’s a sign that there is air in the system or cavitation, which happens whenever there is not enough pressure. If this issue is not addressed, you may face serious consequences, so it needs to be corrected right away, and in most cases, this problem can be solved by locating the point through which air is entering your system.
Leaks
Both interior and exterior leaks are problematic, and a lot of hydraulic leaks happen inside the machine, often without any exterior signs of a malfunction. Exterior leaks, however, will result in decreased performance, drops in pressure or oil on the outside of your pump, so these would be more noticeable and would indicate that you have a problem. Replacing a valve or seal may solve the problem, so look into it right away; otherwise, you may experience system-wide failure.
Leaky Seals
Your seals should not leak, so if you see that they continuously fail, it may be the result of a bent or misaligned rod that your pump may be operating with. Professional technicians may be able to repair your existing equipment, although this will depend on the extent of the damage. Repairing your existing equipment would minimize your costs while allowing you to get the most out of your equipment, so this option should always be considered.
