pump cylinder interior diameter?

[fullmetaljacket]

Can anyone with a (Hills, FX?) PCP pump kindly enlighten me as to what the interior cylinder/pump head diameter is?

I'd love to help but my pump is buried under 101 other things in the spare room at the moment as I'm redecorating my bedroom..

Why do you want to know? I can tell you that it's a two stage pump (compresses air on both upward and downward strokes) so if you want to work out the internal volume it's not as simple as just working with the ID of the outer cylinder.

If you have had no luck by this time next week (when everything should be normal in my house again) I'll have it to bits and have a quick look for you

Cheers for the links, I'm just trying to figure out exactly how much downward force is exerted on the handle at maximum pressure, a kind of 'workout equivalence' if you will.

I'd guess about 50K at the top end
