SUMMARY

The discussion focuses on the design of a pulley suitable for use in 10-25m slurry or seawater, emphasizing the advantages of floating seals over lip seals in high-pressure environments. Participants highlight "Simrit" as a notable supplier of floating seals and recommend "Parker" for their high-quality O-rings and polypacks, which can withstand pressures up to 72,000 psi. Additionally, inquiries are made regarding design guides and standards for floating seals, indicating a need for comprehensive resources in this area.

PREREQUISITES
  • Understanding of floating seal technology
  • Familiarity with pulley design principles
  • Knowledge of high-pressure sealing applications
  • Awareness of industry standards for seals
NEXT STEPS
  • Research alternative suppliers of floating seals beyond Simrit and Parker
  • Explore design guidelines for pulleys in high-pressure environments
  • Investigate relevant industry standards for floating seals
  • Examine technical specifications and performance data for polypacks
USEFUL FOR

Engineers and designers involved in pulley systems, sealing technology specialists, and professionals working in high-pressure fluid applications.

Some question about floating seal

Hi, everyone,
I am designing a pulley that can be placed in 10-25m slurry (or you can treat it as sea water I think).
Some ppl suggest that using a floating seal is much better than lip seal with back bone in such relatively high pressure situation.

Due to the above situation, I wonder the following issues:
1. apart from "Simrit", who are the common international suppliers of floating seal.
2. is there any guide book that can help me to design a pulley?
3. what are code of standards that regulates the size and spec. of floating seal
4. Is there any other issues that's needed to be notified apart form the specification stated in the sales catalog?

Thanks for your kind help and your precious time.

heres a couple seal sources

we use orings from parker, and both their web tech info, and tech support are very good
the polypacks are some of the nicest seals I have ever seen. we use them up to 72Kpsi and they also last a small lifetime
