Hmm, not so sure, I think I might have got a bad ‘un . It won’t pump above about 500 psi, the non return valve doesn’t seem to be non returning. I’ve changed the spring and o ring, cleaned everything up and it’s still the same. Every downwards pump it just bounces back up again if there’s any resistance. I’ve had enough messing about with it now, asked for a replacement and we’ll see what happens? Jury’s out atm.

just got a hills mk5 one myself as you said problems with refills etc.a bit more expensive at £165 but got it from best fittings as they were cheaper than amazon.free postage too.their service was very good and only took less than 2 days to deliver.no problems with this one and have filled the hw100 up to 200 bar.does take a fair bit of effort to get above 150bar but not too difficult.

Well I’ve just received a full refund and can keep the pump. I’m thinking that I might as well strip it down completely to see if I can find the problem. The thing is, it pushes air through the open end of the whip, but when the whip is connected or stoppered I get rebound as if the air is coming back up into the ram. I’ve changed the spring and seal in the non return valve, but it’s made no difference so I’m a bit baffled.

I think the whip might be a bit big in bore size. I need a 1/8 bsp adapter so I can try my other whip.

Well bugger me its here already! ....

 

[tomburras 2,721]

Iv put it together and pumped it up. It just needed a tighten as the guage, hose etc was a bit loose. It came with a bag of spares. I pumped it up and its held its pressure for 20 mins so far not a movement on the guage. Im made up with it, I can't understand how they do it for the money!

 

[tomburras 2,721]

The hose is fitted with a qd adapter that takes standard size best fittings, which is a bonus. Im that impressed iv ordered another to put away.

Looks good. I can’t get mine up to that pressure. Don’t know what’s wrong with it but I got a refund and still have the pump. I might invest in one of these. Have you pumped a rifle up with it Tom ?
