Brand new pumps like that will make a horrendous clatter until they're primed.Then they go quiet once the fluid goes through.

I took the mechanism out of the burned pump and put it in the coil of the 'new' one, took a bit of brute force, I suspect they are not intended to go together. 

Tested the machine and it works perfectly now. So there you go, if you burn the coil of a stairville smoke machine, you can replace it with the coil from a coffee machine pump. 

Cool.

Usually when you disassemble electronics/mechanical parts you'll be left with some extra bits.. I recall my smoke machine is missing a part or two from the pump after taking it apart and cleaning it, it produces thicker smoke now.

If you are left with extra bits after you've put electrical or mechanical machinery back together you have done it wrong and are incompetent and more importantly NOT SAFE. 

Anyone reading that should not accept that as normal.  

You need to be more careful, more methodical and logical and take more notes/pictures. Lay components / fittings / fasteners out in a pattern or different pots or on paper or card, number them. Whatever it takes to make sure you havent missed something.

Maybe if I was 8 years old.

There are no parts missing, its just a hybrid of two different pumps.

The voltage & wattage of the ebay one looks right - so should work. 




Would any variation in flow rate matter? 


That´s obviously related to the power, but should be more or less the same. As noted above, these pumps are pretty much generic devices.

You could also replace with a larger pump, but then may damage the control circuitry. That usually uses either a relay, or triac to fire up the pump. It looks like yours has a relay, which can be a bit more 'robust', in that the pump will draw 5 or 6 times it´s run current on startup, so risks blowing an (undersized) triac - especially if you´re constantly switching the pump. The problem is that the relay contacts will spark & pit over time, so 6 of one, half a dozen of the other.

That may well be but there is no part taking things apart if you haven't replaced the fuse first to check, just in case.

OP, The pumps in these tend to be very generic I wouldn't be surprised if it works.
