Just change out the slotted screws with knurled cap screws, hang a hex key nearby, and I always oil soak my paper gaskets that are xerox copies of an original and my impelker changes are near as fast as just the time to get the impeller out .
The knurled cap screws - do you know the size of the screws?

Why? Once set up, CNC is much cheaper for actual production.

I'm sure that's what he meant. The cost is probably driven by single source low volume.

I don’t know for sure, but I suspect that they were not made in a CNC machine shop. I spoke to the owner when I bought mine and he said they would make them for me. It did take about a month to get them. I think they made them as they got orders in. Maybe not the most cost effective but that may have been due to the fact that there are many different pumps out there and maybe they didn’t have the capital required to set up a large production and stock lots of Speedseals. Don’t know for sure but I am extremely disappointed that they have gone out of business because it is an excellent product.

I hear you. I have 2 sources (one in house at my work and one other guy who makes prototypes for us) where I could get these made. I'm going to see what the cost might be.

Someone could make parts for them and step into a good business. Let us know if you find a source. The teflon wear plates and O rings have been a topic on another thread.
