Fluid Contamination Control: What You Need To Know


Did you know that over 70% of all hydraulic system failures are caused by contaminants in the fluid?

Ingression of solid particulates, liquid, and air bubbles are constant threats for hydraulic equipment. Without proper filtration, these contaminants can impact your vital equipment in many ways:


  • Reduced hydraulic system efficiency
  • Reduced lifespan of machine components
  • Damage to cylinders, pumps, motors, seals, and other important system components.
  • Expensive repairs and machine downtime
  • Catastrophic failure of hydraulic equipment while in operation

Hydraulic filtration is the key to controlling contamination and protecting your equipment.

Schroeder Industries is a global provider of high-performance, high-efficiency filtration solutions, including our range of onboard hydraulic filters. Our experts can work with you and your team to determine a treatment plan for your hydraulic fluid and guide you towards the optimal products and solutions for your filtration needs.

Case Studies: Hydraulic & Lube Filtration


Don’t just take Schroeder’s word on the quality of our products. Here are just a few success stories highlighting how hydraulic filters from Schroeder Industries’ Hydraulic and Lube group saved our customers money, downtime, hassle and more!



When a Frac Drilling OEM in West Texas was facing delivery delays and contamination issues with their filters, the experts at Schroeder stepped in to provide a cost-effective, high-performance filtration solution.

Schroeder Industries upgraded the OEM’s system with the QF5i, featuring an innovative magnetic filter rod.

The QF5i’s magnetic filter rod increases capture of metallic particles and improves the overall dirt holding capacity of the new filter elements by preventing ferrous particles from reaching the element.

The increased dirt holding capacity and overall longer life expectancy of the filter elements allowed the OEM to save substantially on the cost of replacement elements alone.

Here’s how this OEM benefited from this Schroeder Solution!



Dirt Holding Capacity:

+73% (40 µm)
+254% (25 µm)


Element Life Expectancy:

+40% Versus
Competitor


Element Cost Savings:

40% – 60%




An OEM manufacturing a variety of hydraulic refuse trucks sought ways to improve the design and efficiency of their side loader model.

When Schroeder Industries performed a Tank Optimization analysis, our experts saw clear opportunities for tank performance improvements and downsizing.

By combining next generation BRT in-tank filtration and an optimized rotomolded reservoir design, the customer was able to downsize their reservoir substantially!

Here’s how this OEM benefited from this Schroeder Solution!



Reservoir Reduction:

-19 Gallons
-335lbs


Initial Cost Savings:

$380 USD per Unit


CO2 Reduction:

-450lbs CO2 per Unit



You could be Schroeder’s next success story!
