Fill HPA Tank with Hand Pump?

Hey guys, while doing some research on Airguns, I came across some information stating that some of the PCP (Pre Charged Pneumatic) Airguns operate via an on-gun reservoir that can be pumped to over 3000 PSI using pumps such as the following:

Using a hand pump for PCP air rifles.

Now I was wondering, if I were to buy one of these High Pressure Pumps and the necessary air fittings, would I be able to attach a normal HPA tank (i.e. a 13/3k) to the hand pump and pump my way up to a full tank?

I don't see why not, but understand how much pressure and volume is in one of your tanks. It would take a LOT of pumping to get anywhere.

If you're really bored I suppose you could try it..I guess at worst it'd be a hell of an arm/pec workout. But for reference, the average car or bike tire is inflated to around 30-60 PSI...so figure 100x the amount of strokes at minimum (assuming linear stroke per charge, which is probably not likely).

I've seen this question asked quite a bit referring to the pyramid air pump. IF you follow the instructions correctly for it's use, it would take you over 8 hours of continuous use to fill a 68/4500 air tank.

So 13/3000 would be a breeze......lol

You will end up rebuilding the pump every time you attempt to fill your tank. The pumps are made for short term use not prolonged constant pumping. Every 45 minutes you have to let the pump rest for an hour then you have to service. every 3-4 hours of use you will need to replace all the seals. Figure 250 = for the pump figure 50-75 in parts and materials every time you fill. If you are rich and can afford to through out money go for it.

best bet buy a used scuba tank 50-100 , fill station 30-50 fill at a scuba shop 8

A few years ago, there was a kid on another forum that was using a similar pump to fill his tank. He stated he would pump all week while he was watching tv and he would get just over 3300-3500 psi by the weekend to play. It worked out for him as the feild he played at had no HPA and the closest place to fill was more than an hour away. He noted that the pumping gets progressively harder as the pressure builds.

Well, using the following chart I've determined that it would take about 1 hour of pumping to fill a 13/3000. Does that sound right?

I think closer to an hour and a half. But is it really worth it?
