Which crimper should I choose: electric or manual?

A pressure gauge (pressure pump) is a device that is used to check the systems of heat and water supply, ventilation, shut-off valves for tightness with increased pressure. There are two types of pressure gauges: manual and electric. Manual pressure gauges are a container (tank) for liquid in metal or plastic design, a pressure piston, a lever, a pressure gauge, a pressure hose with a fitting for connection to the system.
The electric pressure gauge consists of a self-priming pump, a built-in pressure gauge, a set of hoses (suction and discharge) and an electrical connection cable. Pressure pumps are also divided into classes according to maximum pressure.:
1 – up to 20-30 bar (atm.);
2 – up to 50-60 bar (atm.);
3 – 100-120 bar (atm.);
4 – 150 bar (atm.) and above.
The performance of manual crimpers is determined in milliliters per cycle (ml/cycle) - the volume of liquid supplied in one lever movement, and electric - in liters of liquid injected into the system in one minute (l/min).
The process performed by the above devices is called hydraulic testing, or crimping. These works are carried out not only at the final stage of installation of engineering systems to check the tightness of the system before delivery to the Customer, but also once a year at operated facilities in preparation for the new heating season.
In order to choose the right pressure pump for you, you need to answer the following questions::
- how often will it be used?
- What are the volumes of the systems that are being tested?
- is it possible to connect to the power grid?
- how much time are you willing to spend on the test?
In case of irregular use of the equipment and in cases where the volume of the tested systems is small (private houses, individual risers, etc.), a manual pressure pump can be used.
If the operation of the device is intensive, which is usually the case in construction and installation organizations involved in the installation and repair of internal and external engineering systems, an electric pressure pump is the best option.
Special attention should be paid to the volume of systems that are being compressed: when testing systems of large industrial buildings, apartment buildings, and pipeline sections of outdoor networks, when the system capacity can be tens of liters, using a manual crimper is ineffective, because to pump 1 liter into the system, you will have to make from 30 to 100 movements. Electric pressure gauges pump 6-20 liters/min, which allows testing the system in just a few minutes. Saving time in this case is very significant!
However, if there is no power supply at the location of the hydraulic test, then it is not possible to use an electrical device. Gasoline or diesel generators are usually used to solve this problem.
Currently, the market of equipment for testing engineering systems is represented by a large number of manufacturers: Rothenberger (Germany), Ridgid (USA), CANDAN (Turkey), Virax (France), V-Test (Republic of Belarus). The product range is expanding every year: more and more pipe and shut-off valve manufacturers are also producing pressure pumps.
To make a final choice in favor of a particular equipment, you should answer the above questions, as well as familiarize yourself with the characteristics of the equipment in more detail.
