Hydraulic Oil Filtration & Purification

Hydraulic Oil Purification

Meeting Your Hydraulic Systems’ High Oil Purification Standards

Most hydraulic systems ship with minimal or no filtration system. In an ideal world, there’s no way for fine particulates and other contaminants to enter these closed systems. Filtering our hydraulic oil contamination likely doesn’t seem like a top priority.

But you don’t operate your hydraulic stamping presses and other equipment in an ideal world. You work in the gritty world of manufacturing. In the real world, your system’s breather elements need to draw in air to keep the hydraulic oil flowing and providing lubrication. That air brings with it particles, moisture, and other contaminants. As those contaminants accumulate, they drag down efficiency, decrease the precision of operations, and damage the high-performance electrohydraulic servo valves your hydraulics depend on.

A simple filtration approach isn’t enough. Periodically flushing your system and its reservoirs and recharging may seem like an acceptable solution. But doing so poses significant risks: Pumping out your tanks churns up the debris that’s settled throughout your hydraulic system and reservoirs. Without proper intervention, those contaminants will degrade your fresh oil and destroy your valves.

The ideal contamination control regimen focuses on ongoing particulate management and moisture removal. Such a solution needs to be designed to meet your specific challenges–not some generic filtration spec. That’s what it takes to consistently minimize equipment failure mechanisms, catching them wherever they may creep in.

A filter alone is not enough. We can provide comprehensive fluid purification for the full range of conventional hydraulic oil formulations, as well as non-oil fire resistant hydraulic fluid. This system can be portable off-line, in-line, or “sidestream”/“bypass” filtration, in either fixed or mobile configurations.

Reclaiming Hydraulic Oil

Some applications are plagued by oil continuously leaking and seeping in large quantities. You can recover that hydraulic fluid, even if it’s getting contaminated by water, additives, and other materials. Trucent can help you capture and reclaim that lost oil, filter out water and any particulate, and return the fluid to its OE specification. This will save you a significant amount of money, both in reduced purchases of new hydraulic fluid and by paying less to dispose of smaller volumes of contaminated hydraulic fluid.

Other oil filtration services might try to reduce this contamination with filter media. At Trucent, we have found that a filter media oil filtration approach cannot sustainably handle real world contaminants in the long term.

Trucent has a better way: our comprehensive oil filtration solutions apply the right technology at the right stage, including high-speed three-phase vertical disc stack centrifuges, like our CentraSep DX. This promises fewer interventions, less downtime for maintenance, and more consistent results. Most importantly, it will help you escape the maintenance cycle that comes with dependence on media-based filtration for capturing contaminants.

And Trucent can go even further. We can install a team in your plant to run and manage all your fluids and filtration technology on a daily basis. Your in-house Trucent team will handle fluid buying, oil analysis, and then stay on board to monitor and maintain those fluids at appropriate levels and concentrations. When those fluids are spent, we’ll dispose of them with minimal negative impact to your business and our world.

No one else offers this level of comprehensive service with all hydraulic fluid formulations.

Every solution begins with a conversation. Contact us today to begin that conversation, or schedule a no-obligation on-site consultation. Let’s find a better way to get more from your hydraulic  fluids, every day.


Comprehensive Hydraulic Oil Purification/Filtration Solutions & Services

Trucent provides comprehensive solutions to hydraulic oil purification and reclamation challenges. We can assist with oil filtration services and other maintenance for existing centrifugal separators or design an entirely custom particulate removal solution. We can install one piece of equipment or an entire team to manage all your filtration technology on a daily basis. The goals remain the same: Consistently cleaner fluid, longer tool and equipment life, higher quality parts.

Die Caster Avoids Shutdown and Saves over $20,000


Cross-contaminated hydraulic fluids created safety and waste issues for a die-cast customer.


Within 12 hours of the call, the fluid manufacturer verified that approved fluid specifications were restored, and plant process engineers verified that the plant was ready for full operation. More than 98% of the off-spec fluid was recovered, and the fire-resistant hydraulic fluid was retained.

“Quick responses, personal service, and knowledgeable technicians are able to achieve desired results with little fuss or disruption of our process.”
