This little tidbit of info from scotch is great! not only for the seal that we use but also stirred my thoughts as to other applications.
I own a granite fabrication bus. and run three inline c.n.c. machines that are driven by five horse motors that use a mechanical seal on the main spindle.
Use to get the seals from Italy for 135.00 U.S. took an old seal to the local pool store and found the exact same seal for 37.00
Thinking outside the box has saved me a chunk of money. Thank You Scotch!!!!!!!!!
Just to add for info, mechanical seals are serviceable provided the seals are not cracked. The seal faces can be lapped and o-rings replaced making them as new again. There are many companies out their providing the service. I would say if a seal can be bought for under $35 a replacement is the way to go however if a replacement is over $35 or no longer available, refacing is an option you could investigate.
