Air Venturi (Hill) MK5 Hand Pump

[mtnGhost]

I have a Hill MK4 that I use mainly with my Leshiy 1 and Mutant while hunting in the mountains. Wanted to get a second hand pump and spare rebuild parts for peace of mind, but when I saw the MK5 in stock on AGD/PA - I placed an order. 


With that said, I wanted to see if anyone else has either used one or (fingers crossed) can tell me if they're better / worse than the MK4's. Do they feel like an improvement over the previous model?

...looks like you are the pioneer...

I guess so!!!

Let us know how it is, because I thought the mk4 was already pretty good. They do advertise less effort though.

Yep, that and support for higher pressure (4500psi/310 bar). I'll find out on Friday!!!

Thanks in advance for the report.

It claims to be easier to pump to 4500 PSI. There's a trade-off between easier to pump and volume per stroke. So I presume that although it is easier to pump to high pressure you get less volume per stroke so you need more Strokes. I have an old MK3 it pumps well over 4500 PSI. Although it needs a hell of a lot of force to do so.

My $40 Chinese pump us easier to pump than my Hill MK3.

I just received my Hill MK5 yesterday. Pumped up my Brocock bantam HR to 250 BAR no problem. Never had a MK4 so can't compare.

Nice!!! That has a 480cc bottle, right? How long did it take roughly?

Be careful about the water. Every time I used my Mk3 a little water mixed with silicone grease and wear particles were expelled after I loosened the bleed screw. This is before I added a large > 1QT pressurized desiccant filter before the input to the pump. Now usually get no water filling a small 90ci tank from 3000 to 4500 without bleeding from start to finish. I recently filled the tank from empty to full and I got a small amount of water from the bleed valve. I won't do that again and will only fill 1/3 of the tank before bleeding in the future.

Yes it has a 480cc bottle. I started at 80 bar and did 100 pumps waited 15 mins then 80 pumps wait 15 min then 54 to finish it off. So 234 total. I'd say the time actually pumping was ~ 10 min with the 15 min breaks to allow the pump to cool. The next time I shot I am going to stop at 150 bar and see how many pumps to fill. Will post an update then.

Does it actually say MK5? I ordered a MK5 from Pyramyd, but was shipped an MK4 and am being told they're the exact same (by Pyramyd). I have an inquiry in to Hill but they are closed in the UK already today.

 

[mtnGhost]

It arrived! Gave it a quick test, and it seems to be a little slower than my MK4. I recall there being a small break-in period though with my old one, but it took around double the pumps to get it up to my Leshiy's fill pressure (250bar).

After hitting 250, I was able to fill it to just under 300bar with relative ease. I say relative, because this one feels a little more efficient than the MK4 (outputs more high pressure air with slightly less effort).

 

[ctfish]

So where did you all buy your MK5 from? Here was the "MK5" that Pyramyd sent me, and I'm a bit leery to try them again. I'd rather not have another 6+ week wait (9/26 to 11/10) and get a MK4 again.

Here's what I received from Airguns of Arizona for Hill MK5

I got mine from AGD. Did they give you a Dry Pack with yours? (They boxed mine separately with a QD fitting)

So far, so good! This pump is a little more efficient and doesn't flinch when I get the pressure up to max.

 

[ctfish]

Dry pack was in the hill box for me

So if I was going from 100 bar to 230 bar just to top off my gun how much effort would it take? Seems like these would work well in the field just to top off your gun if you didnt have a tank or power access.
