Manual pressure test pump: specifications, manufacturers, description and reviews

The prevention of communication equipment is a prerequisite for maintaining the proper operation and durability of such systems. This is especially true for pipelines, since the formation of problem areas on its surface can lead to unfortunate consequences. One of the primary preventive operations in this case is leak testing. There are different approaches to this task, but most of them involve the use of special devices and assemblies.

The simplest equipment of this group is a manual pressure test pump, the use of which is available to both a specialist and a home technician. Such tools are used to audit water supply and heating systems as part of routine inspections, after repairs and before putting the facility into operation.

Device and features

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

Most of these elements are designed to provide control of the working fluid, in particular for controlling 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 plants, gas cylinders and other equipment.

Almost all modern models are characterized by a high-strength body made of metal alloys. Also, capacity, regardless of volume, has a 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 the device for carrying the unit, and the direct function of controlling the hydraulics. The pressure test pump is also equipped with a pressure gauge. For the present, this device is supplied as an optional addition, but its usefulness in the process of using the instrument is difficult to overestimate.

What are the differences from electric models?

There are two types of pressure testers. The first variant is represented by manual models, and the second one by electric models. In both cases, the developers use the principle of hydraulics. That is, the tools function is performed by handling water filling. After the pressure is injected, the instrument will allow you to perform the necessary measurements and, possibly, detect abnormalities. Now it is worthwhile to consider in more detail, than a pressure test electric pump differs from a manual one. The first version presents more ergonomic, accurate and easy-to-use models. Manual assemblies involve the operator in the process of performing operations, so their accuracy is less high.

Despite the advantages of electrical appliances, their field of application is considerably limited in comparison with the second version. The lack of electricity does not allow the use of such devices. For this reason, a hand-type pressure testing pump is often used on temporary construction sites where there is no access to electricity.

Main technical characteristics

The variety of models determines the same wide range of values by technical characteristics. Nevertheless, we can consider the average category of such devices as a reference point for optimal data. So, first of all it is important to take into account the maximum pressure of the device, which is usually 60-70 bar. The design parameters, which the pressure pump possesses, also affect the possibility of application in certain operating 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 instrument varies on average from 3 to 7 kg. The characteristics of the manometer are also important, again, the average values of its scale usually do not exceed 60 bar. As for the dimensions of the crimping machine, they are small. The standard case can have the following dimensions: 32 cm in length, 26 in width, and 20 in height.

Reviews about Rothenberger models

Most experts first of all consider options for import models. Judging by the practice of using, one of the most reliable and accurate instruments in this segment is the Rothenberger test pump, designed to work with small diameters in water and gas supply systems. Users note and ease of handling such devices. By the way, in the initial line you can find versions with a mass of 5 kg, which in this case do not cause difficulties in the movement due to the ergonomic handle.

Feedback on models "Instance"

There are also attractive versions of Russian production, among which are the products of "Instance". 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 possibility of operation in conditions without power supplies, such models allow servicing a wide range of plumbing systems. At the same time, users mention the accuracy of the manometer, which is equipped with a manual pressure test pump. The price for the "Instance" model is quite democratic - the initial level is represented by equipment from 4 to 8 thousand rubles. In this range, you can find pressure testers with high-quality metal casing, compact dimensions and good functionality.

Reviews about models «Saturn»

Another domestic producer, the Saturn Company, deserves attention. In the manufacturer's range, there are not so many options, but the modification of "Nir-60" received a lot of flattering reviews. This model is appreciated, above all, for the ability to work in a variety of environments, including oil, water and antifreeze systems. The advantages of plumbing include the system of disk brass valves, which are supplied with a pressure testing pump from the firm "Saturn". Thanks to these devices, the device is capable of providing constant pressure over a long period of time. This device is also praised for its wide range of equipment, which includes a functional manometer and a high-strength reinforced hose.

Price list

In the budget segment of simple devices with minimal characteristics and modest functionality, you can find options for 3 thousand rubles. Of course, such equipment will not work for responsible areas, but for a one-time use in testing ordinary pipes with a small diameter it will do. The middle category is represented by models with a pressure of 60 bar and a liquid capacity of 12 liters. This is a standard test pump, the price of which varies from 7 to 15 thousand rubles. Not so popular is the class of expensive models for 20-30 thousand rubles. But if it is a question of working on large facilities with large diameter pipes, then without such equipment also can not do. As a rule, these are devices from foreign manufacturers, since domestic devices in the mass are designed for work with small-sized pipes.

Conclusion

With this device, you can perform a wide range of preventive operations. The main purpose for which a manual pressure test pump is purchased is to check the tightness in pipelines in areas that do not have access to either mains supply 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 directions.

Thus, the functionality of pumps is expanded due to modern measuring instruments, and reliability and durability are achieved by using high-strength steel in the structure.
