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.
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.
Our client’s micro corrector was experiencing water intrusion past the gasket, caused by improper seal material and configuration.
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
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.
Case History #ST091 – A Chemical Processing Plant Success Story
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).
