Hi folks.

I bought a manual pump that on the site was described as 250bar capable, then i read the manual and it states up to 200bar. Pissed!

Complicated and unconfortable to send it back so i was wondering, how can i push it above 200 bar without destroing the seals? My rifle is 250 bar, still seems that at 200 it's when i get the best performance, but still. It's a hatsan pump.

Thanx
 
You can buy seals that are upgraded in durability. Perhaps a 90 durometer if yours are 70. It's not a perfect solution. Often times the higher durometer seals don't seal as well as lower ones. You might need to get slightly thicker ones to compensate. Honestly I wouldn't bother. I'd send it back or keep it and just pump to 200 bar. My Chinese pumps said 4500 psi capable and seals blew in the foster fitting at 3600. I think the huben handpump is a good choice for higher pressure like that. Goodluck.

It's been several years since I pumped. Only had an old Benjamin pump and it got to be a REAL PIA trying to keep it working. Yep, the seals are what goes and the one that went more than all the others combined was the one at the bottom of the plunger … which meant that I had to take the whole pump apart to get to it. As I said … a royal PIA … got to where I was spending more time replacing seals than pumping. I must have re-built that darn pump 75 times, sometimes it lasted a month sometimes a week. Heat in the pump is your main enemy and destroys the orings in fairly short order and I was only filling up to 3,000 psi. Some say to only pump about 50 times and rest until it cools down. I tried just about everything, different Duro ratings on the seals, different thinkness, different lubes etc … nothing worked very long.

There comes a point in time where you simply say "enough is enough" and you end up buying a compressor. When and where you come to the point of complete frustration is different for everyone … but if it were me in your situation … I'd get myself something that I can work with. Yeah, it will cost a lot of money, but if you get a good one it will bring a smile to your face.

Raden hit the nail on the head. The huben hand pump is your best bet if you want to pump to higher pressure with ease. I’ve had mine for 2 months now and it only gets hard to pump when I’m up to 270 bar. Achieves the higher pressure than other pumps with less pumping. It really is the best hand pump out there. I’ve had the Benjamin and hill pump and they don’t even come close to the efficiency and ease of the huben pump. Not to mention this thing is built like an abrams tank! The main reason I bought it is because it’s small and light enough to fit into my backpack. Although, if you don’t have a compressor already I would suggest buying a yong heng compressor for $250 rather than a $325 hand pump. Unless you already have a compressor then go for it! As far as pushing your 200 bar rated hand pump, it probably won’t last long pumping to higher than rated pressures. Just make it your emergency pump and get a huben pump or YH compressor

Thanx guys, lot's of good info here.....even if not what i was hoping hear but I suspected that my pump would not be enough. I just got my first pcprifle and set and already out of budget so yes, will pump till 200 letting cool down and as soon as possible i'll get a huben or even better a small compressor.

Hate when they mistake with descriptions. Anyways, i have spare seals in case the first set blows up and will have a look for upgraded seals.

Damn!

Wow people still using hand pumps? I remember back in 2010 I used to use a hand pump lol. Once i got my compressor, bye bye hand pump. I will never go back to hand pumping ever again. I toss all my hand pumps, Benjamin, hills mk4 and cheap chinese pump, all in the recycling bin. Compressor are $300-400. If you cant even afford it maybe this hobby isnt for you. Cause pcp are really expensive. I think I'm in the $15,000 range on all my pcp guns, tanks, compressor, ammo, chrony, etc.

He can afford this hobby, he has the 3 things needed: gun, air source, ammo. He’s just on the beginner level of PCP. According to your logic you shouldn’t be in the hobby either. There’s guys out there that have compressors that are worth more than the $15,000 you have in ALL of your gear. You should just say bye bye to your sub $1000 chinese compressor and trade all of your gear in for a “real compressor” then get yourself a few AAA guns. If you can’t afford that then maybe this hobby isn’t for you. Do you see how skewed that sounds? It’s like saying just because you can’t afford a Lexus you shouldn’t drive at all. There’s nothing wrong with starting out where your budget allows

What Hatsan pump do you have? I have a Hatsan Tactair 3 handpump that is supposedly good to 250 Bar according to the owner’s manual. I have only used it to 3000 psi. By the way it is just a rebranded chinese air pump, and I have had some problems with It as far as having to rebuild it several times after little use. It working now, but just use it as a backup for my scba.

Dear 2fast2furious,
Click to expand...

you spent in at least 10 years of hobby 15.000$ with all your 2fast2furious gear, that's 1500$ per year.....a bit less than what i spent in the last week for rifle, scope, pump, ammo, still i don't feel "smarter" than you. But the point it's not even this, but the fact that i have too many hobbies (fly drones, sail my boat, just got an electric scooter.....) so i have to put a budget (initially wanted to spend around 500/600€ but ended in 1500) specially in something that i still have to discover if i like or will practice so intensively that a compressor would justify the purchase. It's not very clever to use words like "if you can't afford" with people you have no idea. Cheers.

I have used my Hill pump for years,Pump all my pcps;usually 2700psi,some to 3200psi.the last 500psi is harder.I pump 40 pumps wait 1-2 minutes then 20pumps ,sometimes more ,then another 20 and so on...the pump can get hot,you do not want that to happen...

I like hand pumping and I like my Hill pump,never been rebuilt +I do no more than 3 pcps at at time...after a while I do get tired...I just want to shoot....oh takes about 120 pumps to get 2800-3000psi....

I admit most are small cylinder pistols.....and Crossman Challenger ,Discovery,Gamo Urban....

Tell you this,it puts a smile on my face when I get over 40 shots between pump sessions....most PCP I have get 26 or so shots.

I am Jesse and like to use my hand pump....truth be told...maybe because I want to keep my expensive low...I know I have just as much FUN.

Wasnt attacking anyone to telling anyone to not to get into airgun. OP stated he just bought his first pcp and already out of budget. That means he doesnt have the money. I was simply saying and giving some advice to someone new into airgun that pcp is no joke. It is a expensive hobby and will cost thousands of dollars. So they can decide whether they really want to invest in pcp or go break barrel. If someone doesn't have the cash, I say stick to break barrel. It will be cheaper.

I use my Hill MK3 to 4500 psi all the time and am still on the original o-rings. I only do 50 strokes at 2 seconds per stroke and then let it rest for 5 to 10 mins before repeating until I reach 4500 psi. I don't recommend that others do the same as you have to be very strong and heavy to do it without assistance. However it does speak for the reliability and robustness of the Mk3 if you don't overheat the o-rings.

I have an older style, steel bodied, Hatsan pump. I don't use it anymore but it still works. I used to fill a gun to 230 BAR regularly, no problem. I sometimes use it to test filters and fittings for leaks at up to 300 BAR. The instructions are a bit contradictory but the gauge's green zone goes to 250 bar, so I assume that it's OK to go that high if you must.

Ha, my Greek and Italian is a little poor so not sure I can entirely decipher that web page, but I think your pump is this one: https://www.opticsplanet.com/hatsan-pcp-hand-pump.html which in case it does apparently only go to 200 bar. I think it was probably an older model. You could probably push it a little beyond 200 bar and see if works but would have to be careful that the hose and fittings are up to it. Like CMshooter said in an earlier post you could tune your gun down a bit and it sounds like it might already be there anyway since you said it shoots good at 200 bar. I have my Marauder set up for field target right now where my best shots start at 2300 psi and end at 1800.

As one other (above) noted...just a heads up.

You DO NOT want hot air going into your gun's air chamber.

Like the other poster noted, 40 or so (I use 50 as a max.) pumps at a time. Let the pump cool. Normally takes more than two minutes, I normally wait five or so..

Just remember when the lower portion of the pump is hot, so is the air. Hot air creates moisture. Moisture is not good for the gun. Pumps (like the Hill) that have a desiccant chamber on them, they don't really do much. The desiccant is on the "inlet" side of the pump, in reality, it NEEDS to be on the pressure side.

So just remember, to be kind to your gun, 40 to 50 pumps, let stand for about 5 minutes (or until cool), 40 to 50 more pumps, let cool, and so on.

Your gun, your money, do as you see fit.

Mike

Thanx guys. I will try today, slow pumps and i guess my 200 pounds will help. My rifle should give 100 efficient shots at 250 bar but i saw a review where the shooter got the fastest shots around 200 bar. Probably i will pump till that value, maybe try to push a bit further to 220/230 with completelly cold pump.....but i really don't care to get 20/25 shots less.

Yes, looks like my pump. The red zone in the gauge starts at 200 on mine and end scale is at 300.....will give a try. ;)
