water strainer for cooling water

I have a Sherwood E20 water pump on a Palmer P60 inboard. In the past the impeller lost vanes and one broken piece stuck in the pump exhaust port. The question is can I add a water strainer on the cooling line after the pump to catch broken vane pieces if this ever happens again? Currently installed is the blue Globe impeller. Old neoprene impellers do not last as long.

Any ideas would be appreciated....Dean

Yes. It doesn't affect the pump.



Somebody here came up with the idea. I'm in the process of adding after pump strainers on several diesels.

Re: water strainer for cooling water

Yes you can, Iíd recommend the ones that donít have a real fine screen, and you can simply unscrew the cover to clean.
Iím doing it soon myself, just had to take apart my heat ex to get the blades out, today.

I am going to have to remove the stock elbow rubber hose and replace it with a much longer one that is looped so that I can fit the strainer in.
I like silicone hose, it seems to last years longer than rubber and doesnít seem to get hard a crack like a rubber hose does.

I bought one very cheap on aliexpress & have been using for about 1 year. Leaked a bit but thread tape cured that. Doubt a more expensive name brand will leak. Will make the impeller last forever now I got strainer on .lol. As A64 pilot said cant have too fine mesh as will clog with sea life. Ours had that problem but I just drilled holes in the mesh to fix.
