Case Study - Rapid Prototype CNC Cap Seal

View All Case Studies

CASE STUDY: Custom DuPont Kalrez® Grommet

GFS’ customer is a leading manufacturer of level measurement technology. Their product lines are within RF admittance level instrumentation as well as hydrostatic, ultrasonic, and more

CASE STUDY: Garlock MILL-RIGHT® ES for Chemical Manufacturer

GFS’ customer is a global leader and manufacturer of specialty chemicals and natural materials, such as: monomers and polymers, surfactant blends, polyglucosides, and oils.

CASE STUDY: BACK-UP RING ASSEMBLY PREVENTS EXTRUSION

GFS' customer manufactures reliable filter & distillation technology for pulp & paper, chemical and petrochemical, and semiconductor applications. Their membrane technology helps to reduce load on energy-consuming evaporators or distillers.

CASE STUDY: DIAPHRAGM FLAPPER PART

World leader in medical and dental instrumentation, specializing in the fabrication of precision instruments. Customer could not maintain their in-house fabrication and required outside help from Gallagher Fluid Seals.

CASE STUDY: CRITICAL STERILIZER GASKETS

Customer is a world leader in biomedical research that strives to uncover cures and genetic solutions for diseases. Customer needed to identify material specifications and find a functionally equivalent supplier.

CASE STUDY: RAPID PROTOTYPE CNC CHANNEL CAP SEAL

Through design consultation with the customer, GFS recommended an O-Ring energized seal package (2x seal) in UHMWPE. Utilizing the GFS rapid prototype CNC machine, parts were fabricated quickly and efficiently, matching the design specifications required by the customer’s application.

Garlock Split Guardian Case Study

The improved sealing solution with a Garlock Split Guardian Isolator provided greatly increased uptime, less maintenance, and most importantly, eliminated the fire hazard due to the increased temperature resistance.

CASE STUDY: MECHANICAL SEAL REPAIR AND REFURBISHMENT

GFS partnered with EagleBurgmann to disassemble and clean the mechanical seal, exchange the seal elements, refinish and replace two seal faces, replace the flange, re-assemble the seal, and leak-test it. The precisely-performed seal repair and refurbishment doubled the life to 18+ months.

Replacing Graphite Gaskets with Kalrez 4079

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.

CASE STUDY - UPGRADING ROD SEALS TO AU30000 POLYURETHANE

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.

CUSTOM-MOLDED FFKM BLADDER

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.

CASE STUDY: SPRING ENERGIZED PTFE SEAL

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.
