Things I liked: At the time, seemed like the price. For the first year it worked as designed.
Things I would have changed: Had I did more research, I would of discovered there appears to be a design flaw with the pump. After about a year, there is one small o-ring that goes bad. Of course it is in the most difficult places to get to. Searching some air gun forums, I found the fix. The upside is the size o-ring can generally be found at a hardware store. The down side is those o-rings dont last long either.
What others should know: Spend the extra cash and get the Hill Pump. Otherwise, buy lots of those o-rings. One afternoons day of shooting, I had to change out the o-ring three times. Now I can tear the pump down, replace, re-lube the pump in about 10mins. But I should not have too. And Yes, I do let the pump cool. I do 20 or 30 strokes, take a break, load up a magazine, then do some more pumping, but it still fails.
Things I liked: Built very heavy duty, very sturdy. Great handle grips, allowing a good hold while using.
Things I would have changed: Definitely needs a much longer hose as the one that comes on it only allows you to fill the rifle by laying it on the floor. It would be much better if the hose was longer so the rifle could be placed on a table allowing you to view the pressure gauge better while filling. Also could use a larger stand to place the feet on while using. The one it comes with is sort of small and makes it a bit awkward to use the pump as your feet are very close together affecting balance.
What others should know: Overall this is a very good pump. I can top off my Benjamin Marauder ,25 caliber from 2,000 p.s.i. to 3,000 p.s.i. with 90 pump strokes. It gets a bit strenuous the last 8 or 10 strokes but being a body builder it is a mild workout for me; for a 150 lb. person it would be quite challenging I would imagine. For the money you can't go wrong with this pump.
Things I liked: Pump is sturdy and will last a long time if you take your time pumping. That means pump 50 times and rest for at least 5 minutes. Then pump again.
Things I would have changed: Of course, the major problem with this pump is that the O-rings burn up from too much heat. Not much you can do about that, they are the weak point of any pump whether you are talking about the Hill pump, the AA pump or the Benjamin pump. My seals went out the first time after about 4 months. The pump is not hard to re-build and you can get all the O-rings necessary to do a complete re-build on the pump from Sun Optics USA. They are the makers of the pump. Look them up on the net and use the phone number supplied on the web site and order as many kits as you want, they are not expensive at all ... somewhere around $6/ kit. Instructions on how to re-build the pump from start to finish can be found on youtube without any trouble. The ONE thing that I would stress is that you DO NOT use silicone grease as the lubricating substance for the pump and O-rings. Let me repeat that with as much emphasis as possible ... do not use silicone grease! Yes, I know, everyone will tell you that you
What others should know: are supposed to use it, but even Sun Optics does not recommend it anymore. It will not lubricate long enough or well enough to keep the seals in good condition ... and you'll be in the same position you were in to start with in short order if you use it. I shoot a lot because I am retired now and have the time to kill and I have re-built this pump at least 25 times. When I used silicone grease, I would have to re-build almost every month, not my idea of fun. The secret to getting long life from the seals is to use Nuvair 455. It is a premium Synthetic Food Grade Breathing Air Compressor Fluid and it is not a problem if the pump becomes hot and will protect the O-rings MUCH better than silicone grease is able to. It can be found on the net also. A bottle will last you forever. I know, I've experienced the same frustration as many of you here have and felt like throwing it in the garbage can ... resist the urge and try my suggestion or contact Sun Optics USA.
Can this pump work with the 13 inch cubic air Venturi bottle?
Yes. It can charge that bottle to 3000 psi without issue.
Does this pump come with rebuild kit? The Venturi comes with 3 sets
It does not
Doe you sell the o ring that goes into the hose attachment that connects to the tank in the gun?
Not exactly sure which part you are referring to, but Pyramyd might have it. You can try either calling the tech department there or Crosman directly.
