Can you damage a pneumatic airgun if you pump it too much?

not much damage can happen if you pump your gun to much. unless you go way overbaord
the ones from the stores have a bleed hole to make sure there is not to much pressure.
so even if you pump more, you wont get any more pressure.
thats why they are rated under 500 fps.
now if you plug the bleed valve, well , thats a different story....

WOW, well, sounds like way to much, could have worn out your piston and valve, give it some time to rest, the cup my have heated up a bit.
as long as you dump all the air out there shouldent be a problem.
that being said i am not an expert of how the daisy works.
i can easily pump my 2289 20 to 30 times no problem, i placed a lighter spring to make sure all the air is dumped.
have a look in the canadian air gun forum, tons of info. and im sure you will find info on how to sort out the problem with your daisy

damage
Have owned several and for instance the older .20 cal. Benjamin Sheridans: you most certainly were damaging the seal and weakening the spring applying the proper pressure to keep it closed-off! More then the max. adviced 8 strokes would, after a short while already result in a leaky valve; wich renders the gun useless, unless replaced!

"Can you damage a pneumatic airgun if you pump it too much?"
Pffffff
Uh, no, I'm not being an a$$. That's just the sound your air gun will make if you pump it too many times

Lesse now...
On a airgun that is normally rated for a single stroke, most of them don't even have an air chamber to store the compressed air in, so pumping it a lot will mostly just make you sweaty. Pressurize the air. release the pressure, repeated. The air the pushes the pellet out, is stored under pressure between the piston face and the valve.
Easy way to tell if yours is like that (aside from reading the ****ing) instructions, is that the pump arm will pop out when you go to pump in another stroke.
On a gun like the Crosman's (wood and steel, not the plastic toys)or Benjamin's, pumping over the recommended amount will slowly reach a point where the air pressure cannot force more air into the storage chamber. A really close fitting and properly adjusted pump cup seal will get you a slight improvement. Some guys have increased the amount of volume of the storage chamber, and this increases the total number of strokes worth of air that it will take, as well as increasing the power. It also makes the rifle need to be pumped a lot more times to just plink with.
Some of the Crosman's have a pressure release valve built into their storage chamber to vent pressure over a set amount. More pumps is just exercise. See comment to follow re: pins.
The linkage pins on the Benji's are a weak point, and if they do not get the lube they need, you will need new ones soon. And a new pump arm. The Crosman ones are a bit better, but still need the lube.
The pump arms can buckle if you overdo it.

Mostly, don't cry when it breaks. If you follow the instructions, it'll usually work as advertised.

I fixed 1 for the kids today (X2). Does it build pressure? Or do you hear air escaping as you pump? If so, it's just an O ring. A philips screwdriver and 5 screws will have it pulled apart (other than removing the piston). Very simple inside them if you have a basic understanding of them. PM me if you have questions about dismantling/assembling the 840 while it's fresh in my mind.
trevj is right about the single pump guns in that they only retain each pump. Extra pumping is just extra wear. You have to remember the 840 is designed for little ones and you can blow the O ring if you pump & fire quickly.
