How are the pumps that come with the Disco holding up? I was told by a vendor that they are having problems with them.

Disco pump for 100 plus fills on my Discovery the last 60 days.I have shot over 4,500 pellets in my .177 Disco and the pump is holding up fine.

If you do happen to get a lemon it will show itself pretty quick and Crosman has a 30 day warranty on the pumps, I believe..

Like I said, mine works like a champ..no problems at all.

I've read if you don't pause every 50 pumps or so and let pump cool,you can damage seals in pump if it overheats...

riun the seals.

I actually I will go further and say pump at a slow steady rate in blocks of about 25-30 strokes. Rest a minute or two and then continue.

I top off my Disco with two blocks of 25-30 strokes during each fill and like I said, have had ZERO issues with my pump(knocking on wood right now as I type this..LOL)

Will pump 50 strokes, then take a break (usually get a cup of coffee). From then on, it's a shorter break every 25 or 30 strokes. Does take a bit of time to fill some of the large volume guns/HPA tanks, but for a Disco will usually get it done quickly with just one cooling break (pumping from 1000 to 2000PSI takes about 50-60 pumps).

Haven't owned all the pumps, but have owned 4. IF they work right from the start and you keep them from over heating as described above, they seem to last for years. A bad one will usually show it's fault within the first dozen fills.

Would be that 90% of the dead pumps are killed by over heating. That little final o-ring is small, and the focus of all the pressure/heat generated....they cook.
