Gallagher Fluid Seals’ customer is a manufacturer of processing equipment that serves industries, including: food and beverage, automotive, pharmaceutical, and chemical. Their product lines include: fluid bed systems, coating and drying equipment, and mixer granulators.
Gallagher re-engineered the existing PTFE seal, made improvements to the lip geometry, and provided material selection guidance based on application parameters. The material change to UHMW-PE reduced seal wear, equipment downtime, and preventative maintenance.

Difficult seal applications come from all industries and sectors of the economy.
While far-reaching operating conditions certainly consume their fair share of engineering hours, often one constraint also probes the boundaries of sealing technology and design ingenuity: limited hardware space.
The Client’s Issue
A manufacturer was using a pneumatically actuated cylinder to dispense a chemical in a production process. The piston was drawn back in the cylinder thus filling it with the chemical product. The piston was then pushed forward to dispense the chemical out of a nozzle.

Gallagher Fluid Seals helps meters & instruments manufacturer through the design and fabrication of a custom-molded gasket with an engineered profile.
The Problem
Our client’s micro corrector was experiencing water intrusion past the gasket, caused by improper seal material and configuration.
The Approach
Gallagher Applications Engineer Benjamin Mell worked closely with our client to identify & address the issue and suggested sending a sample of the instrument to GFS headquarters. Our engineering team received the hardware and investigated the root cause of the seal failure.
GFS engineers observed that our client’s closed-cell

Seals are the most crucial element of a fluid power system, and the engineers at Gallagher have spent more than 60 years cultivating their fluid power sealing skills.
Fluid power seals need to be able to survive higher pressures and more extreme conditions, while having to seal against evolving fluids.

DuPont™ Kalrez® – Total Cost of Ownership Analysis
The drive to reduce costs and environmental concerns have caused many design and processing engineers to turn to perfluoroelastomer sealing parts as the most cost-effective sealing solutions. The value-in-use of perfluoroelastomer can be proven in operating conditions where conventional elastomers fail. Even under less arduous conditions, DuPont Kalrez perfluoroelastomer seals can be the best solution, as they can last significantly longer than conventional sealing solutions.
Economics depend on the total system cost
When considering the economics of elastomeric seals, it is vital to look beyond the total cost related to the sealing solution. The total system cost in use is the sum of the cost of the O-ring seal plus the installation cost plus the downtime cost (including loss of productivity through leakage and clean-up costs).
