SMACO High Pressure Hand Pump for pneumatic guns

Here is a high pressure pump from China which appears to be a clone of the Swedish FX high pressure pumps that use 3 concentric pumping tubes to reach 3000 psi. A lot cheaper in terms of price, but their durability is unknown, however may be OK for pressurizing a "Black Sea" and other high pressure hydropneumatic guns as they require about 100 bar or 1,500 psi. The innermost pump barrel in a thin rod pushing into a close fitting bore which makes such high pressures possible, albeit with a lot of pump strokes and using all your body weight on the pump handle.

This is the patent diagram for the FX pump and was no doubt eagerly read by the engineers at SMACO!

This is the operating leaflet that comes with the pump. Very tiny writing, but hopefully it is legible.


This was slightly crushed inside the package, but I put it under a heavy book for a week to flatten it out, still has a few creases in it which show up on a scan.

Re: SMACO High Pressure Hand Pump for pneumatic guns

There are lots of eBay sellers with sales adverts replete with many glossy photos advertising the SMACO breathing units, but just why this user would need one is unclear.
