How to Prevent High Pressure Seal Failure? DMHUI Preventive Maintenance Guide

Common Causes of Seal Failure:

• Excessive Pressure: If the pressure exceeds the seal's rated capacity, it can cause excessive wear and failure. Solution: Select DMHUI’s high pressure seals rated for 30MPa or more, such as the Viton TCV seal, to ensure leak-proof operation in high-pressure systems.

• Improper Installation: Faulty installation can lead to misalignment or damage to the seal, causing failure. Solution: Follow the manufacturer’s installation guidelines carefully and use proper alignment tools.

• Contamination: Contaminants in the fluid or on the sealing surface can cause the seal to fail prematurely. Solution: Keep the sealing surface clean and ensure that fluids are properly filtered.

• Temperature Extremes: Exposure to extreme temperatures can cause materials to degrade and seals to fail. Solution: Use DMHUI Viton seals that are specifically designed to handle extreme temperatures ranging from -40°C to 200°C.

Preventive Maintenance Tips:

• Regularly inspect seals for signs of wear, leakage, or damage. Early detection can prevent costly repairs.

• Clean and maintain sealing surfaces to avoid contamination buildup.

• Monitor the pressure levels and ensure they remain within the specifications of the seal.

• Replace seals at regular intervals based on the manufacturer’s recommendations, especially when exposed to high-pressure or extreme-temperature environments.
