Indicators of Hydraulic Pump Problems

When you’ve been in the business as long as we have, you tend to know when hydraulic pumps are going to start breaking down. You know what to look for. Little things here and there that tell you trouble is coming. But there are also fairly common issues that come up that you need to know about. When it comes to replacing a hydraulic pump, here are some key questions you need to ask.

Is the Pump Leaking?

Obviously, you have an issue if your pump is leaking, but the severity of the issue might depend on whether you have an internal leak or an external leak.

If you have an external leak, you’ll usually have a pool of fluid somewhere. So make sure to keep the workspace and environment around the pump clean. That way if you have an external link it’s easier to spot.

With an internal link, you won’t be able to see it, but other parts of the system should see a decrease in efficiency, and you’ll probably get overheating, so check for high heat or a slow response. Another indicator of an internal leak is increased cycle time.

Does Your Pump Sound Right?

When you use a machine on a frequent basis, you know what it’s supposed to sound like. If you start to hear grinding or knocking, you’ve got a problem. Many times, the cause of unfamiliar noises is cavitation somewhere in the pump.

Is Your Cycle Time High?

Take a look at the actuator on the pump. If the time to run a complete cycle has gone up, then you probably have a leak somewhere. If the time has increased then you’re going to get additional wear and tear on the parts in your pump.

Is Your Oil Too Hot?

You always need to keep an eye on the temperature of your oil. It should be around 120 degrees and not more than 150 degrees. If you get more than 150 degrees your oil will start to oxidize and that can cause corrosion if you let it continue to operate that hot.
