The low cost of high-grade PTFE diaphragms
The correlation between performance and savings has many more variables than simply the cost of a diaphragm compared to how long it functions before failure. Simply put, Garlock makes high-quality diaphragms that save manufacturers money.
For aggressive pumping and metering applications, PTFE is a very popular choice.
Besides being one of the most chemically inert materials on the planet, it offers high-temperature resistance, and the ability to meet the strictest certifications and requirements.
To complement these desirable characteristics, Garlock uses PTFE that has improved dynamic and mechanical properties.
Enhanced high-grade PTFE is achieved by using manufacturing methods that physically alter the material in a way that is not achievable with the conventional (skived) PTFE manufacturing process.
Increasing the strength, flexibility, and permeation resistance of a diaphragm material can...
