Industry Pain Points

Hydraulic systems and heavy-load lubrication systems act as the power core of industrial equipment, and their operational reliability directly determines the continuous operation rate of production lines. Statistics show that approximately 80% of hydraulic system failures are caused by fluid contamination. Four major contaminants lead to system breakdown: solid particles, water, entrained air and sludge.

The fitting clearances of hydraulic pumps, valves and cylinders generally range from 3 μm to 50 μm. Tiny hard particles such as iron filings and silica dust scratch the mating surfaces between valve spools and valve bodies, which may result in spool sticking and response failure. Water mixed into the oil emulsifies lubricants, accelerates the consumption of additives and causes corrosion on metal surfaces. Colloids and carbon deposits generated by oil oxidation block throttle holes and jam sliding valves.

In heavy-load lubrication scenarios such as gearboxes and bearings, accumulated metallic wear debris (iron, copper, tin) aggravates gear pitting, spalling and bearing fatigue failure, which may trigger catastrophic equipment damage.

In addition, under high-temperature working conditions with oil temperatures ranging from 80℃ to 180℃, including injection molding machines, die-casting machines, continuous casters and hot rolling lines, the filter paper adhesive of ordinary filter elements will soften and peel off, while sealing components harden and lose efficacy, resulting in reduced filtration precision and fluid leakage.

Solutions & Applications

1. Filtration & PurificationOur lubricating oil filters and hydraulic filter cartridges adopt high beta values (βx ≥ 200), which can effectively remove metallic wear particles and carbon deposits from oil and accurately maintain oil cleanliness up to standard NAS grades.

2. Adaptation to Harsh Working ConditionsWe supply high-temperature resistant hydraulic filter cartridges for high-heat working conditions such as continuous casting, hot rolling and injection molding, supporting stable filtration performance at operating oil temperatures up to 180℃.

3. Cost-Effective Import SubstitutionWe provide interchangeable replacement oil filter cartridges compatible with global mainstream brands including Pall, HYDAC, MP Filtri, Parker, MAHLE and Donaldson. Our products deliver equivalent performance while drastically cutting customers’ operation and maintenance costs.
