Frequently Asked Questions (FAQs)

Q: Why choose a multi-spring seal over a single spring?
A: Multi-spring seals distribute load evenly, offer longer life, and handle higher operating parameters.

Q: Can the springs be isolated from the process media?
A: Yes, we offer designs with non-clogging internal arrangements and metal parts outside the process fluid.

Q: Is it suitable for corrosive or abrasive fluids?
A: Absolutely. With options like Silicon Carbide vs. Tungsten Carbide faces and PTFE/Viton elastomers, it’s ideal for tough media.
