Click For Summary
The discussion centers on the design of a pulley for use in slurry or seawater environments, emphasizing the advantages of floating seals over lip seals in high-pressure situations. Participants seek information on international suppliers of floating seals beyond Simrit, design guides for pulleys, and standards regulating floating seal specifications. Recommendations highlight Parker as a reliable source for seals, noting their technical support and quality products. The conversation also touches on the durability of polypacks used in high-pressure applications. Overall, the focus is on ensuring effective sealing solutions for demanding conditions.

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

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
