In the mining industry, equipment reliability directly affects safety and profitability. A large mining company faced chronic seal failures on their excavators operating in dusty, abrasive environments. These failures led to hydraulic fluid leaks, increased maintenance downtime, and rising operational costs.

Application Background

The client’s excavators operate in open-pit mines under extreme dust and debris exposure. The original sealing solution failed every 6 months, requiring frequent fluid top-ups and unscheduled maintenance interventions. Downtime was estimated at 15 hours per intervention.

COMBI Solution Customization

COMBI engineers conducted an on-site assessment and proposed a multi-lip sealing solution with integrated dust exclusion channels. The seals were designed using heat- and abrasion-resistant materials tailored for hydraulic actuators exposed to particulate ingress.

Performance Results

Following installation, the COMBI seals operated for over 18 months without any leakage or performance degradation. Dust ingress was virtually eliminated, and maintenance intervals extended from monthly to quarterly. Total unplanned downtime dropped by 70%.

Client Feedback

According to the site maintenance engineer: "COMBI’s sealing solution has completely changed our approach to equipment uptime. We’ve seen a major improvement in reliability and reduced operating costs. It’s become our new standard for high-risk systems."
