Where do I look first when confronted with hydraulic pump failure?


A broken hydraulic system isn’t obvious to address unless you are aware where to look for the main symptoms. Since it’s not always about a visual symptom, as you may think of a problem that pops our right in front of your eyes like a structural damage and you cannot miss it ! Unfortunately, you seldom realize a bit too late you need to actually repair your hydraulic pump, sometimes you risk reaching the point of no return and you definitely need a complete replacement of your hydraulic pump. Anyway, if you do know what kind of ‘symptoms ’ to look out for, you can even try solving some of these hydraulic issues yourself..

Spot #1 : Oil level is too low

If the pump’s oil level is too low, your hydraulic system won’t work properly or not even at all. The same fact is available for every type of motor or engine. If you make sure that your oil level is always optimal, the same way you take care of it for your own car, then obviously you need to do the same for your hydraulic pump.A reservoir left uncovered or even an air leak can be the reason of your lack of oil. A defected suction line will lead to an impossible oil flow and a not properly covered reservoir will lead to spill the oil out. If you are lucky to detect in due time this problem, then you can limit the harm brought to your unit.

Spot #2 : Installation is not made properly

An incorrect installation may lead to a pump malfunction and that might be the most probable scenario I’m afraid, especially if you did it by yourself. In any case, even if the installation was made for you by another person it might still present some issues. Important to consider is the fact that if the installation is not made properly, the pump won’t be able to work at all. An inaccurate installation will prevent the smooth functioning of your hydraulic pump since its pipes must attach themselves seamlessly to the pump from the very beginning. Otherwise you can be confronted with lots of problems due to complementary external loads.

Spot #3: Corrosion due to aeration and / or cavitation

Two of the most encountered problems that lead to a pump failure are aeration and / or cavitation. This means that you have either air or vapor in your pump’s oil. The main symptom is that you will get a noisy or bumpy sound which is caused by both of these issues. The pump housing and pressure plates will get corroded eventually due to the air bubbles and vapor present inopportunely in your oil. Usually the intruder air bubbles get from undetected suction leaks, instead if there is a full restriction in your pump then you will experience most probably a cavitation due to the vapor present in your pump oil. A specialist help as Hydraulic Center in Timisoara is obviously necessary if you experience these symptoms and you want to solve your pump’s blockages.

Spot #4 : Metal particles issue

Small and very small metal particles are the most often encountered reason for hydraulic pump failure. A unit repair followed by an inadequate system flushing can be reason of pressure plate scratches made by very small metal particles
Even dust particles can cause damage to your pump because they can get so easily through any type of seals. This is why a properly cleaned area around the pump is strongly advised as well as an increased attention at the cleaning factor of the filter necks, funnels and tank caps when opening the tank.

This is our short story about the main reasons why your hydraulic pump could present a malfunction. If you’ve diagnosed any of the above issues, you can contact a specialized service center.

These pump failure symptoms are just a few examples brought forth in order to help you make a basic diagnostic about the pump failure issue you are facing and hopefully you will sort out shortly and cost-effectively.
