All hydraulic systems feature high precision components, which are vulnerable to very small amounts of contamination. Even microscopic metallic particles that make their way between close-fitting reciprocating surfaces can very quickly bring even the most powerful hydraulic systems to their knees.

Hydraulic fluid aeration refers to the presence of air in a hydraulic system in any form including the formation of large bubbles, dissolved air or foam. Regardless of the form, aeration has several negative effects. It causes increased pump cavitation, leading to excessive noise. Air has an erosive effect leading to increased wear on hydraulic […]

Hydraulic fluid contamination is the number one cause of hydraulic system failure and as such it’s a serious concern for maintenance managers everywhere. Hydraulic systems can become contaminated in a number of ways – including poor system design, lack of maintenance or improper maintenance procedures and other contributing factors. In this article, we’ll discuss 7 […]

Hydraulic hoses are an often-overlooked part of hydraulic maintenance, but they are critical to the efficient and safe operation of your machine. If hydraulic fluid is the lifeblood of your machine, then hydraulic hoses are the arteries of the system – containing and directing the pressure to do its work. But they’re also equally dangerous […]

Whether you operate fixed plant or mobile hydraulics, you know that you need to maintain a schedule of regular preventative maintenance in order to keep your equipment performing properly. However, are you truly aware of all the risks associated with hydraulic cylinder failure? The consequences of poorly maintained hydraulic equipment go beyond the cylinder itself. […]

Hydraulic fluid contamination is one of the biggest threats to the integrity of your hydraulic system. More than anything else, contamination plays the biggest role in the premature failure of hydraulic components. And particle contamination is one of the main culprits when it comes to this problem. Particle contamination refers to the presence of microscopic […]

Hydraulic fluid is the lifeblood of your hydraulic system. This incompressible liquid does more than transmit force, it is also responsible for lubricating many moving mechanical parts. The friction-reducing properties of hydraulic fluid prevent components such as bearings, pistons, pump vanes from grinding, eroding and tearing themselves apart. However, hydraulic fluid is a wear item […]

If hydraulic fluid is the lifeblood of your system, hydraulic fluid contamination is its Achilles heel. That’s because even unseen, microscopic particulate matter in the fluid can bring colossal machines to their knees. In this war against contamination, the hydraulic filter is your first and only line of defence. When in good condition, filters will […]

As CEO of Berendsen Fluid Power, James Leach knows more than a thing or two about hydraulic equipment. In this blog, he explains why preventative maintenance is so important – and how it can save your business time and money.

When air is mixed with the hydraulic oil in your cylinders it can create the conditions for an extreme phenomenon known as “hydraulic dieseling”. This happens when bubbles of air mixed with oil undergo extreme pressurisation, causing them to explode in much the same way that diesel fuel ignites within an engine cylinder. Does that […]

Viscosity is the measure of a fluid’s resistance to flow. It is commonly thought of as thickness, or resistance to pouring. Choosing a hydraulic fluid with the right viscosity is important to the overall efficiency of the hydraulic system.
