This case study looks at three typical problems we see in the fluid power industry – side loading, contaminants and increased temperatures.

This case study includes: Hydraulic Cylinder - Side loading, Pneumatic Valve - Contaminants, and Rotary Actuators - Increased Temperatures.

GFS designed a custom sealing solution that would mold the seal directly onto the metal component part, eliminating manual labor. This increased production output by eliminating manual installation.

GFS designed a custom-molded gasket, with an engineered profile, which provided optimal sealing performance in the application. It helped eliminate water intrusion and provided more reliability.

No project is too small for GFS. This customer needed a MASSIVE 80ft diameter tank gasket for their sewage digestion tank. GFS developed an interlocking EPDM gasket for the large containment vessel.

GFS identified the application parameters and designed a custom FKM seal to meet the chemical compatibility and temperature requirements, eliminating failures and increasing output.

Gallagher’s team performed friction calculations to develop a low friction spring energized seal that demonstrated low break-away characteristics, helping to increase seal life for the customer.

Gallagher engineers worked with the customer to develop a custom-molded FFKM compensation bladder. Gallagher collaborated with our FFKM supplier-partner to develop a low-temp 60 duro compound that satisfied the needs of the customer’s temperature, enviromental, and flexibility requirements.

GFS engineers assessed the operating conditions and made a change in compound to a new high-performance polyurethane. The change in compound to Freudenberg’s AU30000 allowed the system to maintain performance, while increasing the life of the seal.

Gallagher engineers worked with the customer to troubleshoot the graphite gasket and reverse engineer a superior seal. After determining Kalrez® 4079 would be a suitable replacement, GFS was able to successfully laser cut Kalrez® 4079 to the appropriate size. The new seal helped eliminate the helium gas leakage in the customer application.
