Prophylaxis of communications equipment is a prerequisite for maintaining the proper performance and durability of such systems. This is especially true for pipelines, since the formation of problem areas on its surface can lead to sad consequences. One of the primary preventive operations in this case is a leak test. There are different approaches to this task, but most of them involve the use of special devices and units.

The simplest equipment of this group is a manual crimping pump, the use of which is available to both a specialist and a home master. Such tools are used to audit water supply and heating systems as part of scheduled inspections, after repair work and before putting the facility into operation.

Device and features

The basis of the design is a pump fixed to the reservoir with the working fluid. One side of the pump interacts with the pressure hose, while the other side is integrated into the hydraulic compartment. Also, the complex is complemented by a distribution block, discharge and suction valves, two valves and a handle.

Most of these elementsdesigned to provide control of the working fluid, in particular to control its supply. Despite the simple design, the pressure test pump can be used as a universal device. In addition to working with pipelines, it is also used in the maintenance of refrigeration units, gas cylinders and other equipment.

Almost all modern models are distinguished by a high-strength case made of metal alloys. Also, the container, regardless of volume, has special protection against corrosion. Manufacturers also take into account user requests in terms of ergonomics. This characteristic largely depends on the handle, which performs both the role of a device for carrying the unit, and the direct function of controlling the hydraulics. The pressure pump is also equipped with a pressure gauge. For the time being, this device is supplied as an optional addition, but it is difficult to overestimate its usefulness during the operation of the tool.

What is different from electric models?

There are two types of crimpers. The first option is represented by manual models, and the second - by electric ones. In both cases, developers use the principle of hydraulics. That is, the function of the tools is performed by handling the water content. After pressurizing, the device will allow you to perform the necessary measurements and, possibly, identify deviations from the norm. Now it is worth considering in more detail how an electric pressure test pump differs from a manual one. The first variety is more ergonomic, accurate and easy to use.models. Manual units involve the participation of the operator in the process of performing operations, therefore their accuracy is less high.

Despite the advantages of electrical appliances, their scope is significantly limited compared to the second variety. Lack of electricity does not allow the use of such devices. For this reason, a manual type pressure pump is more often used at temporary construction sites where there is no access to electricity.

Main Specifications

The variety of models causes an equally wide range of values for technical characteristics. However, you can consider the average category of such devices as a baseline for optimal data. So, first of all, it is important to consider the maximum pressure of the device, which is usually 60-70 bar. The design parameters of the pressure test pump also affect the possibilities of application in certain working conditions. The caliber, for example, can be 3-4 cm, the volume of the built-in container usually reaches 12 liters, and the weight of the tool varies on average from 3 to 7 kg. The characteristics of the pressure gauge are also important, again, the average values \u200b\u200bof its scale usually do not exceed 60 bar. As for the dimensions of the pressurizer, they are small. A standard case can have the following dimensions - 32 cm in length, 26 in width, and 20 in height.

Reviews of Rothenberger models

Most specialists firstconsider options for imported models. Judging by the practice of use, one of the most reliable and accurate devices in this segment is the Rothenberger pressure test pump, designed to work with small diameters in water and gas supply systems. Users also note the ease of handling such devices. By the way, in the initial line you can find versions weighing 5 kg, which at the same time do not cause difficulties in moving thanks to the ergonomic handle.

Reviews about the models "Instan"

There are also attractive Russian-made versions, including Instan products. Such models are presented in different versions with a working pressure range of 30-90 bar. Plumbers testify that the devices of this company are distinguished by their versatility. In addition to the ability to operate in conditions without power sources, such models allow you to service a wide range of plumbing systems. At the same time, users mention the accuracy of the pressure gauge provided with the manual pressure test pump. The price for the Instan model is quite democratic - the initial level is represented by equipment from 4 to 8 thousand rubles. In this range, you can find crimping machines with a high-quality metal body, compact dimensions and good functionality.

Reviews of the Saturn models

Deserves attention and another domestic manufacturer - the company "Saturn". There are not many options in the manufacturer's assortment, but the Nir-60 modification received a large number of flattering reviews. This model is valuedin total, for the ability to work in a wide variety of environments, including oil, water and antifreeze systems. The advantages of plumbing include a system of brass poppet valves, which are supplied with a pressure pump from Saturn. Thanks to these devices, the device is able to provide constant pressure for a long time. This device is also praised for its wide range of equipment, which includes a functional pressure gauge and a high-strength reinforced hose.

Prices

In the budget segment of simple devices with minimal features and modest functionality, you can find options for 3 thousand rubles. Of course, such equipment is not suitable for work in critical areas, but it is quite suitable for one-time use in checking ordinary pipes of small diameter. The middle category is represented by models with a pressure of 60 bar and a liquid capacity of 12 liters. This is a standard pressure test pump, the price of which varies from 7 to 15 thousand rubles. The class of expensive models for 20-30 thousand rubles is not so popular, but if we are talking about working at large facilities with large-diameter pipes, then you can’t do without such equipment either. As a rule, these are devices from foreign manufacturers, since domestic devices are for the most part designed to work with small pipes.

Conclusion

With this device you can perform a wide range of preventive operations. The main purpose for which a manual is purchasedpressure test pump is a leak test in pipelines in areas that do not have access to either mains power sources or water supply. Accordingly, in comparison with electric models, such a device has a high autonomy, due to which it has become widespread. However, manufacturers continue to improve the device in different ways.

Thus, the functionality of the pumps is expanded thanks to modern measuring instruments, and reliability and durability are achieved through the use of high-strength steel in the design.
