Let's talk about dirty oil

Dirty hydraulic oil might not be the first thing on your mind, but when you hear that it’s the cause of more than 80% of system failures, it will certainly make you take a deep breath.


Hydraulic oil is often described as the lifeblood of your machines. And just like your own blood, if its contaminated it can have devastating knock-on effects. In your case, throughout your whole body. In the case of your equipment, throughout your whole system.


That’s why effective filtration is so important to total system health – and especially in aggressive environments. Fortunately from forestry to mining, and in the marine, oil, gas and renewable energy sectors, Parker Filtration offers a total system solution with three key elements: prevention, diagnosis and treatment. 

Prevention – it’s better than cure

If your hydraulic oil gets contaminated, then often the only way to cure it completely is a shutdown. Which means lost production, and inevitably lost profits too. So the most effective way to maintain productivity and profitability is to prevent the contamination in the first place.

In extreme conditions, where even carrying out an inspection can be a health and safety risk, gathering relevant information for the kind of analysis that can flag up problems is a challenge in itself. But using the most up-to-date filtration technology, Parker Filtration can help you spot potential problems before they affect your oil and everything it flows through.

Successful prevention starts with choosing the most appropriate and effective filtration solution, backed-up by on-line sensors and on-site testing technology.

The result will be early warning of issues, so you can take appropriate action to avoid component deterioration or critical failure, and the equipment shutdown that could follow.

Diagnosis – before it’s too late

Even in the most well-regulated working environments, if they’re inherently dirty and aggressive then contamination can sometimes occur. Once it does, then the longer it goes undetected and undiagnosed the more damage it can cause: from a minor issue to a critical failure, and from a short period of downtime for maintenance to a complete shutdown for repair or component replacement.


Parker Filtration systems don’t just filter, but monitor too – so you can be alerted to a problem and diagnose the cause before it goes too far. The insights Parker Filtration systems provide into equipment health are based on identifying the smallest changes. Then the systems can trigger crucial interventions, before what starts as a minor issue develops into a major problem.

Diagnostic capability from Parker Filtration includes a combination of sensors and diagnostic tools, plus circuit filtration and off-line systems. Together they provide machine operators with real-time insights into changing machine health.

With all the facts at your fingertips, it’s easier to make truly effective decisions, to improve uptime, minimise downtime, and optimise productivity.

Treatment – the last, or first, resort?

For humans, treatment is what happens when you’re already sick. For your equipment, it’s what happens to make sure it doesn’t get “sick”.

Using up-to-date filtration technology to “treat” your hydraulic oil will help to keep systems clean and fully functional, for greater reliability. As an added bonus, it will also help your oil to last longer.

That in turn extends the time between routine drain and change procedures, with resulting increased uptime, reduced waste, and lower costs for disposal, lubricant and labour.

Correct and effective treatment of hydraulic oil can also reduce the time – and money – needed for maintenance. And when your equipment is running smoothly, with clean oil flowing through your system, unplanned stoppages are reduced to a minimum, and performance and efficiency are optimised.

Total system healthcare

You can rely on Parker Filtration technology to:

  • provide valuable insights to help you optimise performance, streamline maintenance and improve reliability
  • identify potential issues before they become real problems
  • keep your oil – and your systems – contamination free.


In other words: prevention, diagnosis and treatment.


Put them together, and you have a total system healthcare solution that means you never have to talk dirty oil again. And even in today’s highly competitive industrial environment, you can clean up.
