Pumps for air rifles are produced with various stands. Pushers in devices are installed in vertical and horizontal positions. Filters are most often used with expanders. For safe use of the model there are sealing sleeves.
The maximum pressure parameter depends on the quality of the valves. If we consider modifications with horizontal racks, then they have an adapter with a spring. In order to understand this issue in more detail, you should consider the design of a standard pump.
Design and principle of operation
The typical model (drawings of a high pressure pneumatic pump are shown below) includes a round post, a handle and a rod. The devices also have a plunger mechanism. The operating principle of a high-pressure pump for pneumatics is based on increasing the pressure inside the chamber. This happens due to the movement of the pushers. They are located under the filter.
Adapters are used to stabilize the pressure in the chamber. There is a special rod in the pump stand. On some models, the plunger mechanism includes a seating pin. When the handle is raised, it moves to the lower position. When the pushers begin to move, the fitting moves down. The maximum pressure is recorded by a pressure gauge.
Application area
Plunger models are special-purpose devices that create very high pressure, so they are practically not used in everyday life. The main areas of their use are the industrial sector, they are used in the following industries:
- In the chemical industry for pumping substances with high viscosity and their precise dosage in the manufacture of chemical compounds that do not react with metal.
- For supplying measured quantities of water and other high-pressure liquids.
- In the oil and gas industry when drilling wells.
- In the energy industry in steam generators.
- In mechanical engineering in the manufacture of hydraulically driven equipment with operating pressures up to 3000 bar, in the automotive industry in injection systems of diesel engines.
- Plunger water pumps are widely used in car wash service centers.
One non-traditional application for plunger pumps is water jetting and cutting materials. At a pressure of about 2000 bar. A jet of water can remove paintwork or rust without leaving any residue. The technology is widely used in cleaning reinforced concrete structures, the sides of ships and runways. A water jet with a pressure of 3500 bar allows you to obtain the highest degree of cleanliness of WJ-1 surfaces according to the international standard.
Homemade modification
How to make a high pressure pump for pneumatics? First of all, it is important to note that it is easier to make a model with a horizontal stand. To assemble a high-pressure pump for pneumatics with your own hands, first of all, take a cylindrical body. The handle under it should be selected with a small width. The rod is directly connected to the adapter. The top valve of the pump is fixed above the fitting.
A jumper is used to connect the spring. The first grommet is installed at the top of the post. Next, to assemble a high-pressure pump for pneumatics with your own hands, you will need a second valve. To fix it, you will have to use a blowtorch. In this case, it is important to lubricate the fitting well with machine oil. Lastly, install the footrests. The pressure gauge for a homemade high-pressure pump for pneumatics is most often fixed near the jumper.
Do-it-yourself plunger pump in a car wash device
In everyday life, you can use high-pressure plunger pumps for water when organizing car washes with your own hands.

Choosing a quality model
How to choose a high pressure pump for pneumatics? First of all, it is important to consider the power limit parameter. The threshold overload indicator, as a rule, does not exceed 4 microns. The adapter must be made of aluminum. The return spring is about 3.6 cm in diameter.
Good models use two sealing sleeves. The top valve must be fixed firmly. Separately, when purchasing a device, the foot rest is checked. In some cases it is done with side overlays. The handle should be held firmly in your hands and not dangle to the sides. A high-quality model these days costs about 16 thousand rubles.
general information
Pneumatic pumps are mechanical devices that operate using only human muscle power to pre-inflate weapon tanks. They are also used for air pistols.
The accessory for each weapon is different, it is worth reading the material about the PSS Vul pistol.
Their main difference from cylinders is that they are completely autonomous and do not depend on the benefits of civilization.
In other words, with a pump you can live at least for a couple of months in a house by the lake, where there is no water or gas, and hunt as much as you like.
Crosman pump
This high pressure pump for pneumatics is in great demand. Its maximum overload parameter fluctuates around 5 microns. If you believe the reviews of experts, the device uses a high-quality foot rest. The stand in this case is made with a round cross-section. According to buyers, connecting the model to the cylinder is not difficult. The model fits perfectly for PP series rifles. The top valve in the device is made entirely of stainless steel. The pump rod is very rarely deformed.
The permissible temperature level is at least -20 degrees. The sealing sleeve of the model is located behind the adapter. The bottom valve of the device is designed for low pressure. If we talk about the disadvantages, it is important to note that the model uses small pushers. In some cases the barbell wobbles. The handles are made with plastic linings, and they are erased quickly. The model does not have a drying filter. You can buy the specified pump for air rifles at a price of 14,700 rubles.
Brief conclusion on the topic
The PCP rifle is an excellent option for hunting and recreational shooting. Due to the design features, it requires careful care. To lubricate the moving parts of the weapon, it is recommended to use Ballistol brand oil.
It is better to entrust the settings of the PSP to a specialist. It is permissible to do it on your own if you have an understanding of what is being done and how it is done correctly. Incorrect actions will reduce your shooting performance.
Filling the tank with a portable compressor is often done at shooting ranges. Manually pumping air into a container is an unpleasant task for owners, but it is cheaper than filling it with a high pressure cylinder.
The price tag for straight-through rifles is lower than for geared rifles.
They are easier to set up, without overpaying for service. Some of the money saved is worth spending on a chronometer - any one, as well as the necessary parts. October 20, 2022

How to regulate the combat direct flow valve?
Adjusting the BC in direct-flow pneumatics is a necessity. By performing the actions correctly, consistently, a “plateau” is formed - a graph showing the actual speed based on the pressure of the air cylinder. To put it simply, this is the range (corridor) where the initial velocity of the bullet is most stable.
Attention!
The process is not easy and requires the knowledge and skills of the PSP owner. It is recommended to seek help in setting up co-current pneumatics from a specialist.
If the weapon is adjusted independently, then the search for the optimal “plateau” is not limited to the combat valve. The caliber, pressure, spring stiffness, barrel length, mass and type of bullets, and firing pin weight are taken into account.
The reservoir is filled with air up to 200 bar, then shooting is carried out without refueling through a chronograph at a paper sporting target. Without measurements it is impossible to make the correct adjustment.
The task is to achieve:
- stable initial bullet speed;
- accuracy.
It is necessary to find the “golden mean”, receiving N shots with the desired speed and minimum acceptable spread. At the same time, avoiding excess air consumption (sudden emptying of the tank). Firing accuracy should not decrease either.
For example, if a PCP user wants to increase the power of a weapon, then the factory spring is changed to a stiff one. The valve remains open longer - the pressure increases, and the bullet is pushed out of the barrel more strongly. Accordingly, a weak spring reduces the valve opening delay time - the air supply and initial speed are reduced. It is important to consider the mass of the striker. Another way to improve performance is to shoot lighter weight bullets.
A long barrel does not guarantee accurate shooting. What is more important is the quality of the channel, whether there is any bending. Opportunities are determined by shooting.
The results (pressure and initial speed) are recorded on a piece of paper. Every shot should be recorded. For clarity, you can download and install a special program on your PC. After entering the received data, a graph will be created - this is convenient.
Important.
Setting up a “plateau” is more complicated than it seems - there are many subtleties. The price for erroneous actions will be unsatisfactory shooting performance from the PCP device.
Model "Axor"
This high-pressure pump for pneumatics differs from other models by its wide foot rest. This device weighs only 4.6 kg. If you believe customer reviews, problems with the bar rarely occur.

Advantages and disadvantages of membrane equipment
A pump with a membrane system for pumping liquids has the following advantages:
- The absence of a motor and gearbox significantly increases the service life of the pump.
- The design is durable and reliable: all components are easily replaceable and repairable.
- Due to the fact that there are no rotating parts inside the housing, the noise level emanating from the pump is minimal.
- High degree of safety: the pump works even with flammable and toxic liquids. The device freely absorbs liquid with a solid fraction (sand or other impurities) with a diameter of 2 to 63 mm.
- Fire safety: the drive (hydraulic drive) is started by supplying a certain volume of compressed air.
- The pump is ergonomic, compact and lightweight, allowing it to be installed even on a bracket.
- A high level of performance is ensured due to the absence of wearing parts: bearings, seals, rubber or caoutchouc gaskets.
- Availability of automatic leak blocking.
- Adjustable air supply levels for improved performance.
- Automatic shutdown of the pump when there is no liquid.
- The outlet pressure reaches 65 bar, and the liquid suction depth is 5-6 meters.
Among the disadvantages of this type of pumps, the following points can be highlighted:
- The most vulnerable part of the pump is the membrane, which experiences the greatest stress during operation.
- Also, the valves pumping water become clogged over time, which leads to breakdown. For prevention, it is necessary to blow out the valves several times a year.

What are the best riflings for pre-inflated pneumatics?
There are 2 types of trunks - standard and polygonal. The latter have advantages over the classics:
- accuracy;
- low lead clogging of the channel (easier to clean);
- are made by forging.
The disadvantage of polygonal forms is the lack of clearly defined rifling, unlike standard ones. In addition, there are parts with and without choke (choke).
The best rifled barrel is a specific concept, because the quality is determined by the bullets used. For example, a blank with polygonal rifling is optimal for 2.2 gr JSB projectiles, but not suitable for 1.645 gr ammunition. the same company.
There are 3 main types of forms sold in Russia:
- Lothar Weather;
- Lobaev;
- CZ.
If for CZ the choice is modest, then Lothar Wather has a large assortment of blanks of different calibers. It is worth noting the high quality of the LW, but this does not mean that the CZ is not worth a look for the owner of a PCP rifle. The correct approach: a Lothar Wather polygonal twist without a choke with a caliber of 6.35 mm is more suitable for a projectile weighing 2.2 g than a CZ twist without a choke for the same ammunition.
However, there is a hidden subtlety here - the forms are produced using different technological processes. The workpiece could be ground to the required diameter, then passed through with a mandrel, or the process was performed in the reverse order. The quality of the finished product will vary. Turning speed is an important parameter that affects the heating of the barrel blank. The parameter has been slightly changed - the rifling is deformed.
Which cuts to choose? The answer is polygonal, but they deform the bullet into a smaller circle, or evenly.
