Benjamin HPP2KU High Pressure Hand Pump

Great backup in a pinch ! Not great for the only air source for a PCP Air Rifle but it works great when my SCBA 4500 psi Air pack drops below 3000 psi. I'm in my fifties and I have used it from zero psi to 3000 and it will take some time with a few breaks in between to reach a full fill in my Benjamin Marauder. When my primary source runs low it will top it off without too much trouble in a pinch.I have read reviews where people had trouble with o ring failure bit I think it because of user error not the fault of the pump. If you use it like a bike pump and just pump fast up and down it will overheat and fry the o rings. It clearly states in the basic manual that you need to pause for a second at the peak of the up stroke and at the bottom of the stroke. This gives the pump a more efficient stroke and the o rigs will last a long time. Each stroke up and down actually fill the chamber. You Tube has some good videos on the proper technique but if they are not pausing at the top and bottom of each stroke it is NOT correct.One thing I recommend, if you can't afford a scuba tank rated for 3000psi or an SCBA 4500psi (Scott air pack) and a HP pump is the only air source you can afford, you will spend allot more time hand pumping than shooting. The SCBA is the best choice but fill sources are harder to find than for scuba tanks. The scuba tank will obviously drop below the 2700 psi point much sooner but never over fill your 3000 psi max gun. The 4500psi air pack should be regulated to not exceed 3000psi to avoid dangerously over filling. I paid $120 for a used SCBA in great condition, $350 on eBay for a 6000psi regulator and another $65 for high pressure air paintball fill station rated for 5000psi, quite the investment !

Bought the Benjamin pump to match a Benjamin Airbow and everything worked out perfect! Forget all the nonsense reviews you've read, here IS the real truth behind the Benjamin pump!First, it NEVER got hot while pumping my Airbow up from 1,000 psi to 3,000 psi. Even after 25 pumps the entire unit was cool to the touch, so to get this thing "hot" is gonna take someone just "a pumpin' and a sweatin'" nonstop!Another fact worth mentioning for those who don't already own PCP guns....it's the FIRST thousand psi that wears you out! My Benjamin Airbow came with 1,000 psi on the gauge. With the pump connected, the FIRST 1,000 psi is simply pressurizing the line between the pump and the Airbow! That took about 100+ strokes! You see, until you have created enough "line pressure" to overcome the internal valving, your strokes don't mean diddly squat toward increasing the gun's reservoir pressure!As most can figure out, once volume is satisfied, pressure comes up pretty quickly...and this is true of the Benjamin pump. Once line pressure was equal to gun reservoir pressure, "psi" started to come up pretty quick. From 2,000 psi to 3,000 psi wasn't about number of strokes, but about getting the pump all the way down to inject the next slug of air! By 3,000 psi it is extremely difficult to get the pump all the way down unless one is a large person with good body mechanics....so there is that.At the same time, when shooting, if the gun reservoir is recharged around the 2K psi mark, it won't take long at all to be back to 3,000 psi!The Benjamin pump is clearly well made and made to hold up to a lot of use. And, point of fact, pumping up the Airbow was excellent exercise!I highly recommend this pump for those looking, but not expertly familiar with all the pumps on the market!

i purchased this pump for a airsoft/paintball tank. im using a 48 cubic inch 3000 psi tank and it hooks up directly no other hoses required which is a huge plus. it takes about 1000 pumps to fill the tank which will get me roughly 2000-3000 rounds out of my airsoft gun.i am happy with the quality and price for a compressor would have ran me about $3500 or $700 for a shoebox compressor but they take like 4-6 hours to fill a tankthe reason for the drop in 1 star is the physical strength required after you pass about 2000psi gets im 6ft 170lbs and work wil trucks unloading by dolly around 100-250lbs per load and this pump is a harder workout then my job.luckily you can fill the tank in small increments you do not have to fill it all at once but if you remove the hose be sure to bleed it with the bleeder screw first so you dont damage the pump and the next time you connect it to add more air (in a senario where you have not used any just want to add more) it will take about 3 pumps to be back up to pressure and your adding air again.me personally i will continue to use this product it is very handy due to the fact that i can bring it with me to games and no electricity is needed but i will probably only fill my tank to about 2000 psi because the extra time to get that last 1000psi isnt worth it to me YET (ill slowly build my strength and increase it 50psi or so a month)please note that the cylinder will start to get hot/warm i pump about 100 at a time then take a 10 min break so i dont hurt the seals
