Reducing Maintenance Downtime with High Performance Rubber Diaphragms

Repeated seal failures can lead to leakage, production downtime, and increased maintenance costs. A client approached Arvico after facing continuous sealing issues in a critical industrial application where standard sealing solutions were not delivering consistent performance.

Client’s Issue

The client was experiencing repeated seal failures within short operating cycles, resulting in:

• Frequent leakage issues
• Unplanned maintenance shutdowns
• Increased replacement costs
• Reduced equipment reliability

The existing seals were unable to withstand the operating conditions consistently.

The Challenge

The application involved a combination of mechanical stress, temperature exposure, and oil/gas compatibility challenges.

Major concerns included:

• Premature seal wear
• Compression set issues
• Material degradation
• Inconsistent sealing performance
• Need for extended operational life

The client required a long term solution rather than repeated replacements.

Application & Operating Conditions

The seals were used in an industrial fluid handling system operating under continuous pressure and varying temperature conditions. The application involved exposure to process media that affected the performance of the existing elastomer compound. Frequent operational cycles also increased wear on the sealing components.

Arvico’s Solution

We conducted a detailed analysis of the application conditions, seal design, and material behavior. Based on the findings, both the seal geometry and elastomer compound were optimized to improve sealing efficiency and durability.

The revised solution included improved material selection for better chemical and temperature resistance, along with design modifications that reduced stress concentration and enhanced sealing stability during operation.

Manufacturing & Quality Approach

To ensure consistent quality, Arvico implemented controlled compounding and precision molding processes. Each seal underwent dimensional inspection, hardness testing, compression set evaluation, and application based quality checks to verify performance under operating conditions.

Strict process monitoring helped maintain consistency across production batches.

Result & Performance Improvement

After implementing the optimized design and compound solution, the client observed significant improvements in seal performance. 

Key improvements included:

• Reduced seal failure frequency
• Improved resistance to wear and deformation
• Better sealing reliability
• Increased operational life
• Lower maintenance requirements

Outcome

The optimized sealing solution helped the client improve equipment uptime and reduce operational disruptions. The reduction in replacement frequency also lowered overall maintenance costs and improved long term system reliability.
