Pump Wear and Cavitation
Air entrainment and particulate abrasion erode vane/piston pump internals; cavitation pits valve plates, shortening pump life by 40%+.

Powering Motion with Precision: Hydraulic Fluids That Outlast the System
From 35 MPa+ high-pressure circuits to sub-zero startup conditions, KERUN delivers fluids engineered for shear stability, filtration performance, and contamination control—keeping your pumps, valves, and cylinders running longer, cleaner, and more efficiently.
Process Challenges
The Silent Profit Leaks in Hydraulic Systems
Industry data shows up to 80% of hydraulic failures trace back to fluid issues—not pump defects. Contamination, shear breakdown, and viscosity drift work quietly in the background until a vane pump fails at 3 AM or a press loses positioning accuracy. We catch them before they cost you.
Contamination Spiral
Particulate + moisture + oxidized by-products create a self-reinforcing wear loop—more particles → more damage → more particles.
Filterability Drop
Poor shear stability releases thickener "slugs," plugging 3μm/5μm filters and tripping differential pressure alarms.
Cold Start and Viscosity Loss
Wrong VI or base oil choice causes slow priming in winter and thin-film failure at high temp—compromising both startup and load-holding.
KERUN Solution Approach
Precision Filtration, Predictable Performance
Quantify status
Test fluid Physical & Chemical Properties analyze particulate composition, identify ingression sources (breathers, seals). Correlate ISO cleanliness codes with equipment wear patterns.
Lock in performance
Select high shear-stability base oils and additives based on system pressure and temperature. Ensure long-term viscosity retention to prevent pump inefficiency or film collapse.
Reset baseline
Perform circulating flush prior to filling to remove welding slag, scale, and legacy contaminants. Establish required flush velocity and target cleanliness to ensure fluid introduction under controlled conditions.
Maintain stability
Monitor viscosity, acid number, and water content periodically. Use trend analysis to forecast fluid degradation or contamination risks. Execute corrective actions (filtration/dewatering) to prevent unplanned downtime.
