Diana Need information about PCP hand pump

Hello everyone
I just got my first PCP gun "Diana BANDIT" I really like it but it's a little louder than my co2 chaser but much more power
But now here's come filling the gun
I am really on tight budget so I discovered there's hand pump for PCP
I am start looking here and there so I found Chinese pump that cost around $40-$60
And branded pumps cost over $150 to more than $300
I also read about 4 stage 3 stage
But I came across to one of cons of PCP hand pump is that since they contain oil and water sometimes the pump will create moisture and it may leak with air and get inside the gun
Okay is there any way to avoid this? I mean my bandit is small tank only 50cc and I saw YouTube video he fill his pp800 ( bandit same gun) only 24 pump to fill from 100 to 200bar
So what causes of leak water from the hand pump?
Or suggest me PCP hand pump for under $100 and with acceptable quality or at least fill my gun 150 times (24×150 times=3600 pumps 🙂)
Hello and congrats!
As you are aware....Corrosion inside a 2900 psi tank is NOT a good thing!
I realize that you mentioned being on a budget, but .....
Have you checked your local options, for filling up a large, secondary tank for you?
I am fortunate that there is a local buisness near me, that fills my large 88 CF tanks up for $10.
They specialize in equipment for firemen.
Another option is taking a tank to your local fire station, or scuba shop if you live near a coast.
The best thing about this option, is that the air is high quality, low moisture air, made for breathing!
The upfront expense, is well worth the investment in my opinion, especially if you do a LOT of shooting.
If your hooked on PCP, do a lot of shooting, and plan on staying with it for many years, the expense is very minimal!
Also, I have no idea why, but there seems to be a strong demand for old, expired tanks, so your able to re-coup about 1/3 or more, of the inital investment.
I absolutely do not recomend useing a old expired tank, but believe it or not, there is indeed a strong market for them.
Just food for thought!
