Replacing SMC Pump Gasket - Can I Make a Gasket?

[markymarkuk]

Hi

I'm about to take apart an old SMC Comet 2-120F Pump (see Picture), as this pump is no longer available I'm worried that once I disconnect it or take it apart, the gaskets will be ruined. As its old, I'm guessing I cannot go buy identical replacements????
Is it possible to make gaskets, what material, or will that tube of squeezey stuff be ok?
Any advice greatly appreciated.

This picture shows the hex bolts Im going to try and undo

nOt doing any harm or damage so just leave it well alone

Head gasket material from motor stores could work. It may be an O ring seal, in which case simply obtain a new one. Good luck with that. Looks like an old Potterton boiler. If you are serious about keeping that boiler then I would drain and replace the valves and fit a new pump. As said, if the open vent is 22mm then simply remove and plug the safety valve.
112's advice is probably the way to go, but I simply answered your question.

Yes

If still working then my strong advice would be to leave it well alone!

If not working then it would be possible but fiddly to fit new pipework and valves and a new pump.

No pumps now use that flange connection !

you can still get these type of gaskets imported from america, they are cheap but the shipping probably wont be

Really appreciate advice.

The pump is not working properly, so as a temporary fix I picked up an identical pump (but not a flange type) so wondered if I could undo those 4 hex bolts and swap over the pump part.
I'm having a new system installed this Spring, so wanted temp fix to see me through January to April.
One of you were correct, this is an old Potterton open vent system installed in the 70s.

Will my idea work of swapping???

Cheers

When I was an apprentice (some 45 years ago) we used to buy a sheet of gasket material place it ove the flange and gently work with a hammer to cut it to shape.
