An average pneumatic pump of this type will cost around 20 thousand rubles.
Rifle Devices
The pump (pneumatic) for rifles is notable for its compactness. Rods in models are most often made of aluminum alloy. In the upper part of the housing there is a protective cover with a thread. If we talk about the parameters of the pumps, it is important to note that the operating pressure of the system is at least 250 bar. As a rule, two-stage modifications are presented on the market.
Pressure gauges are located in the lower part of the housing. Pushers in devices are equipped with special adapters. Manufacturers make pens with rubberized pads. You can buy a model in stores at a price of 13 thousand rubles.
Modification for piston maintenance
Pumps of this type are characterized by an increased parameter of ultimate pressure. The indicated indicator fluctuates around 310 bar on average. The rods in the devices are available with a length of about 45 cm. Many modifications are equipped with pressure gauges. At the same time, digital devices are rare. On average, the weight of the model does not exceed 3 kg. The mounting pins in the devices are located above the plunger mechanism. It is also important to note that the models have an injection advance clutch.
It is most often made of steel. Handles are made in various widths. Racks are usually made C-shaped. Some models have special filters. To service modifications, sets of keys are often included in sets. There is a pump (pneumatic) of this type not more than 20 thousand rubles.
Transfer pumps
Pumps for pumping liquids are in demand in the industrial field. In this case, the cases are installed cylindrical in shape with a double wall. Many modifications are capable of boasting a high working pressure parameter. Rods for models are used with screw type wraps.
Pushers are mounted directly above the plunger mechanism. Some pumps have a sealing sleeve. It is also important to note that modifications are presented on the market that have a boom longer than 60 cm. The pump (pneumatic) of this type weighs about 3.3 kg, and you can buy it at a price of 13 thousand rubles.
Oil model
Pneumatic type oil pumps are manufactured with and without adapters. It is also important to note that there are modifications with a return spring. Plunger mechanisms in the devices are located in the lower part of the structure. For many models, the case length does not exceed 40 cm. Three-stage modifications are most often presented on the market.
The mass of this type of pump does not exceed 3 kg. Handles are often made with rubberized pads. Pushers in devices are used disk type. If we talk about the parameters, then the working pressure of three-stage modifications is 300 bar. Pressure gauges are installed in almost all models. If we consider two-stage pumps, then they can withstand the ultimate pressure at around 230 bar. You can buy a model at a price of 12 thousand rubles.
Pump crosman
The specified high-pressure pneumatic pump is made with brass valves. The parameter of the working pressure in the system does not exceed 300 bar. Pushers are standardly used disk type. It is also important to note that the plunger mechanism is mounted on a special gasket. There is no filter for drying in this case. A standard set of modifications includes a set of keys for maintenance. The mass of the device in assembled form is 2.7 kg. The user is able to buy this model for 14 thousand rubles.
VAM devices
The pump (pneumatic) of this series is made with a wide handle. The case is made of aluminum alloy. Pushers in the devices are located above the plunger mechanism. The stand is set wide and comfortable to use. If we talk about the parameters, the modification weighs exactly 27 kg, and the operating pressure does not exceed 270 bar. You can buy a pump (pneumatic) of the specified series in stores at a price of 13 thousand rubles.
Model "Axor"
The pump (pneumatic, manual) of this series is made at the factory with a sealing sleeve. This model is classified as a two-stage modification. The grease on the rod due to the protective ring lasts a long time. The standard set of models includes a set of keys for maintenance. At the top of the case there is a special threaded cover. This pneumatic type pump weighs 2.3 kg. The manometer is located near the rack. It is also important to note that the presented device is equipped with a filter for drying. The hose length is exactly 35 cm. The sealing sleeve in the device is mounted on the gasket.
The mounting pins in the housing are located above the plunger mechanism. The fitting in this case uses a small diameter. Directly return spring fastens with pushers. The adapter in this pneumatic type pump is of the cam type. For advancing injection, a special coupling is used. The case of the model is made in the form of a cylinder, and its diameter is 4.5 cm. The handle in the presented modification is not wide, however it is comfortable to use. You can buy this pump in stores at a price of 15 thousand rubles.
Umarex Pump Features
The specified pump (diaphragm, pneumatic) is made with a short rod. Durable pushers are considered a distinctive feature of the modification. Also, the model uses special rubberized pads. The case in this case is made of aluminum alloy. For advancing injection, a coupling is standardly used.
The adapter is located above the plunger mechanism. According to the documentation, the pump can withstand a maximum pressure of 310 bar. The return spring of the model is set to a small length. Directly the fitting over the plunger mechanism is fixed on the rod. To prevent its wear, there is a small sealing sleeve. There are no filters for drying in this pneumatic type pump.
