Metal Fabrication: The Secret To A Great Roll Cage

When Should You Consider Rebuilding Your Hydraulic Pump?

by Sally Burke

Hydraulic pumps are one of the most essential components in a hydraulic system. These pumps help convert mechanical power into hydraulic energy, which powers the hydraulic system. While these pumps are designed to last for years, there comes a time when they may need to be repaired or replaced. This piece will discuss when it's time to rebuild your hydraulic pump.

Decreased Efficiency:

One of the most common signs that your hydraulic pump needs to be rebuilt is decreased efficiency. If you notice that it's taking longer for the hydraulic system to produce the desired force or that the system's performance has decreased, it's time to have your hydraulic pump inspected. A worn-out internal seal or vanes may cause this issue, which can be fixed by rebuilding the hydraulic pump.

Strange Noises:

Another common sign that your hydraulic pump requires rebuilding is the presence of strange noises coming from the machine. If you hear screeching, squealing, or knocking sounds, there may be some problems with the internal components of the hydraulic pump. It may be due to damaged bearings or rotors that need to be replaced by rebuilding the pumps.


If you notice oil or fluid leaking from the hydraulic system, it's a clear indication that there are cracks or gaps in the pumps' internal parts. This leakage can cause serious damage to the machine and even pose a safety risk to the operators. Having the hydraulic pump rebuilt is essential to guarantee the continued safe and efficient operation of the system.

Contaminated Oil:

When you check the oil in the hydraulic system, it should be clean and clear. If it appears murky or contaminated with debris, it indicates that the hydraulic pump is not working correctly. Contaminated oil can cause significant damage to the pumps' internal parts, leading to the need for a rebuilding service.


Finally, the age of the hydraulic pump is another factor to consider. While these systems can last for years, they will eventually wear out and require rebuilding or replacement. If you've been using the same hydraulic pump for a long time and have noticed any of the above issues, it's likely time to consider rebuilding your hydraulic pump.

Hydraulic pumps are essential components in a hydraulic system, and it's critical to address any issues as soon as they arise. Signs that your hydraulic pump may require rebuilding include decreased efficiency, strange noises, leakage, contaminated oil, and age. By resolving these concerns, you can ensure the continued safe and efficient operation of your hydraulic system. If you notice any of these signs, it's the right time to seek a professional's help and have your hydraulic pump rebuilt.
