Hand pump compression: features, manufacturers, description and reviews

Prevention of communication equipment is essential to maintaining proper performance and durability of such systems. This is especially true of pipelines, since the formation of the problem areas on its surface can lead to dire consequences. One of the primary preventive operations in this case is to check for leaks. There are different approaches to this task, but most of them involves the use of special fixtures and assemblies.

The Simplest equipment of this group is the manual compression pump, which is available both to the specialist and to the house master. These tools are used to audit water systems and heating in the framework of planned inspections after repairs and before delivery of object in operation.

Features

The structure is Based on a pump, fixed to the tank with the working fluid. One side of the pump communicates with the pressure jacket and the other is integrated into the Department of hydraulics. Also the complex is supplemented with a distribution block, valves suction and discharge, two valves and a pen.

Most of these elements intended to provide control of the working fluid, in particular to control its flow. Despite the simple construction, the compression pump can be used as a universal device. In addition to working with pipelines it is also used in servicing refrigeration units, gas cylinders and other equipment.

Almost all modern models are high-strength housing made of metal alloys. Also the capacity regardless of the volume has special protection against corrosion. Manufacturers take into account users requests in terms of ergonomics. This characteristic depends largely on the arm, which performs the role of adaptations for carrying of the unit, and a direct function of hydraulic controls. Also, the pump is supplied with a compression gauge. Yet this unit is available as an optional Supplement, but its benefits in process of operation of the tool is difficult to overestimate.

What is the differences from electric models?

There are two types of opressovka. The first option presented in the manual models, and the second – electric. In both cases, the developers use the principle of hydraulics. That is the function of the tools is performed by contacting with the water content. After pressurizing the device will allow you to perform the necessary measurements and, possibly, to identify deviations from the norm. Now it is worth considering more than the compression of the electric pump differs from a manual. The first form is more ergonomic, accurate and easy to use model. Manual units require the participation of the operator in the course of operations, so their accuracy is less high.

Despite the advantages of electrical appliances, their scope is considerably restricted compared with the second variety. The lack of electricity prevents the use of such devices. For this reason, the manual compression pump of the type often used in temporary construction sites, where there is no access to electricity.

General specifications

The Variety of models leads to an equally wide range of values of technical characteristics. However, you may want to consider the middle category of such devices as a basic guideline for optimal data. So, it is first important to consider the maximum pressure of the device, which usually is 60-70 bar. On the possibility of application in different operating conditions is influenced by structural parameters, which has the compression pump. Calibre, for example, may be 3-4 cm, the amount of internal capacity usually reaches up to 12 l, and the weight of the tool varies in average from 3 to 7 kg. Important characteristics of the gauge, again the average values of the scale usually does not exceed 60 bar. As for the size of opressovka, they are small. Standard housing can have the following dimensions – 32 cm length, 26 - in width, and 20 height.

Feedback about the models Rothenberger

Most professionals in the first place considering the options of imported models. Judging by the practice of use, one of the most reliable and accurate instruments in this segment is the compression pump Rothenberger, designed to work with small diameters in the systems of water and gas. Users noted the ease of use with such devices. By the way, in the initial lineup can be found a version of mass 5 kg, which in this case do not cause difficulty in moving the ergonomic handle.

Reviews of the models "Instance"

There are attractive versions of the Russian production, including the production “Instan”. Such models are presented in different versions with a working pressure range of 30-90 bar. Plumbing suggest that devices of this company are flexible to use. In addition to the possibilityoperation in conditions without power supply, such models can serve a wide variety of plumbing systems. At the same time, users mention the accuracy of the pressure gauge, which is equipped with manual compression pump. The price for the model "Instance" are quite affordable – the initial level of the presented equipment from 4 to 8 thousand. within this range, it is possible to find pressovshchiki with high-quality metal casing, compact size and good functionality.

Reviews of the models "Saturn"

Deserves attention and another domestic producer – the company "Saturn". In assortment of the manufacturer there are not many options, but the modification is “NIR-60” received a great number of good reviews. This model is valued primarily for the opportunity to work in many different environments including oil, water and antifreeze systems. The advantages of plumbing includes a system of brass Poppet valve, which supplied the pump compression from the company "Saturn". With these devices, the device is able to provide constant pressure for a long time. Praise this machine and the broad package, which includes a functional pressure gauge and high-strength reinforced hose.

Prices

In the budget segment of simple devices with minimal features and modest functionality, you can find options and 3 thousand RUB. of Course, to work on critical areas such equipment is not suitable, but for single use in the verification of conventional small diameter tubes will fit perfectly. The average category is represented by models with a pressure of 60 bar and a liquid tank for 12 l. This is a standard compression pump, the price of which varies from 7 to 15 thousand rubles is Not so popular class of models costly for 20-30 thousand rubles, but if we are talking about working on large projects with large diameter pipes, without such equipment are necessary. As a rule, devices from foreign manufacturers, as domestic instruments in the mass, designed to work with small pipes.

Conclusion

With this device you can perform a broad spectrum of preventive operations. The main purpose for which the acquired manual compression pump is to leak test the piping in areas that do not have access neither to the sources of the power network or to water supply. Accordingly, compared to electric models, this device has a high autonomy, due to which widespread. However, manufacturers continue to improve the device in different directions.

So, the functionality of the pumps is expanding, thanks to modern instrumentation, and reliability and durability are achieved by applying high strength steel in the structure.
