High Pressure Pumps

[Dead-eye Dick]

I apologise in advance if this question has been asked before but just been looking on that famous (or infamous) website at the small high pressure pumps advertised for filling PCPs at between £200 & £300. Little bit dubious as they all seem to be made in China but has anyone any experience of one of these. Are they any good and more importantly are they safe? Or should I resort to the stirrup pump option!!!!!
Thanks in advance.

Quite a bit of discussion on here about it:

Bit 50/50, some people love the idea but many like myself prefer the assurance of the drive bottle for a dry supply. There are a few folks on here who use them.
Also if you're having a 12L 300bar cylinder filled for £7 you need to refill your rifle with the compressor over 2500 times to break even on cost. I rather suspect the cheap compressor will have died or need servicing by then extending that count further.

That's a surprising amount, can you explain your maths please.

£7 x 2500 = £17,500 these cheap compressors cost a couple hundred quid don't they? - where does the other 17 grand come from?

Brian I did a double take I think he means £7 for the divers bottle, which in turn fills the gun a number of times

Not sure the maths is quite right though

A hundred fills at the dive centre £700, it would be cheaper to throw away the compressor and buy a new one if it went wrong!!!!!
ps that £700 dues not include fuel to get there.

Like anything else your personal circumstances are what makes or breaks the cost, by the time I pay for fuel it costs me about £12-£13 per cyl fill but I probably only fill it once a year.

At that rate even the cheapest on the bay would take 10-15 years to break even, & that's allowing for cylinder test costs,

OTOH for someone who's getting their cyl filled every other month It might pay for itself in 2-3 years, assuming it lasts that long
