Description

GX PCP HAND PUMP 3-STAGE 300BAR

As far as hand pumps go, the GX PCP Hand Pump 3-Stage 300BAR is one of the best models out there today.

Lower in cost than cylinders and compressors, an ideal filling choice for those on a tight budget. Also perfect for shooters looking for a back-up filling method. Made for use on PCP rifles, as well as pistols. Also, you need no electricity to run it, nor to refill it like scuba tanks. So, it is ideal for off the grid airunning, or if you live in an area where there’s no scuba cylinder filling services.

This hand pump is, to be sure, by far the most portable and affordable refill option on PCP airguns. It is also perfect to keep as a back-up filling option. If your scuba tank falls too low, or power outages prevent the use of a compressor, simply grab your hand pump. Of course, you can take it out to the field in a lightweight backpack, or your rifle’s carry bag for on the go refills. Alternatively, you can store it in your vehicle, as it takes up very little space.

Assembly is quick and easy, with the included Allen key fitting all 4 necessary screws. GX included tools for assembly and maintenance, spare seals and parts, as well as some silicon oil and a test plug to maintain your hand pump.

Filling Tips

Note that a PCP hand pump may not fill a completely empty air rifle, because you first need to pressurise the hose and check valve. Which, to be honest, requires significant effort and hand pumps are not designed for filling from zero pressure. The initial pumps only build pressure in the line between the pump and the gun, and it can be hard to overcome the “check valve” until the hose is pressurised.

Use your body weight: Use your body weight to push down on the pump, especially as you reach higher pressures.

Ensure the bleed valve is closed: Before you begin pumping, make sure the bleed valve on the pump is closed tightly.

Pump steadily: Pump slowly and steadily to avoid creating excess heat, which can damage the pump’s O-rings.

Make upstrokes count: On multi-stage pumps, the upstroke also creates pressure. Pause briefly at the top and bottom of each stroke to allow the air time to transfer between the different stages. 

Check the pump’s pressure gauge: You will see the pressure gauge on the pump rise before the one on the rifle, confirming that the line is pressurising.

Let the pump cool: Let the pump cool down every 25 to 50 pumps, or about 5 minutes of continuous use (whichever comes first) to prevent damage.

Maintenance

Being the most affordable filling method, you can be assured that it’s also the most labour intensive. The bigger and emptier the air reservoir on the rifle and the higher the BAR rating, the more you’ll have to pump, of course. You’ll also have to perform some maintenance and upkeep. Refer to the included booklet for recommended maintenance and also make sure to use the pump as instructed. If you take proper care of your hand pump, as with your airgun, you’ll enjoy it for far longer.

We highly recommend that you acquire spare seals for your handpump. Take any spare seals that are included to your local seal / o-ring dealer. They can measure the seals and assemble a few spare kits for you. This is a very inexpensive way of ensuring you always have spares, as importing spare seals alone are very expensive, so most dealers / importers do not import spare seals.

Do not let dirt or moisture enter the moving parts. This will damage the pump, just like a car’s engine.

Very importantly, do not use just any lubrication! Use only pure silicon oil that cannot combust under pressure.
