High-quality hand pump PCP

If you are new to PCP guns or need a replacement part for your compressor, check out this new model. I've spent many hours looking for affordable toppings. It's definitely better quality than the regular hand pump I have, which needs to be re-capped much quicker than I expected. I hope the photos I've attached are clear. It's not something I do all the time, but the quality/attention to detail on this pump is very impressive. The box was securely packaged to avoid damage during shipping. Also, the pump itself was packaged in vacuum plastic packaging, so it shouldn't corrode even if it's in Amazon's warehouse for months. Also included are replacement parts for repairs should you eventually need to reseal. What is unique to me is the design and location of the oil/water filter. While it's true that many pumps have some sort of filter, most are simply coiled tubing of cotton or foam. The best of these are a true desiccant such as molecular sieve zeolite. This is the only pump I've seen that has a filter that's closer to the top of the pump hose. Unique appearance. You can open it and dry the beads to use again and again. As for the GX pump itself, they put a lot of detail into the finished product. The sensor is filled with liquid with unique numbers. It's rotated so you can read it while looking down while pumping. The perforated hose has a metal neck bent upwards so that the connection to the pump cannot be kinked. By the way, the hose is about 20 inches long. I appreciate that the hose includes a simple cord to hold and lock the pump in the closed position. The paint finishes in carbon, black paint/paint, plastic/rubber are very clean. The grips feel solid and comfortable, definitely higher quality than others I have. In addition, the GX logo is printed on the grips. The logo is also in other places. GX has a premium design. The instruction manual is written in broken english, but pretty good english. This is a very detailed and thorough guide. So it weighs 6.8 pounds. A bit heavy, but you can feel the solidity in everything. It took 20 clicks/clicks to increase the pressure in my Artemis PP800 pistol from 110 to 200 bar. For caliber cricket about 45 deep squats of 150-200 bars (much more than a pistol). It feels like it fills up a lot quicker with the GX. In any case, it takes more energy to go down. So saying this is the 3.5 level makes sense. This is a brand new product, time will tell. However, it seems to me that he can keep up with the big boys.

Pros
  • Easy installation
Cons
  • There are other interesting options.
