Pressure tests are carried out when testing the tightness of piping systems in heating, water, and oil installations, solar systems, and during the construction of boilers and pressure vessels. What pumps are used to perform these tests? Read on to find out.
What is a pressure test?
A pressure test is designed to check the tightness of installation pipes. It should be performed immediately after the installation has been assembled, in accordance with the pipe manufacturer's recommendations, and the result should be recorded in the construction log. During the test, a medium is pumped through the installation at a suitably increased pressure—usually approximately 1.5 times higher than the operating pressure. Installation tightness tests are most often performed by the contractor; however, choosing an external company specializing in this type of work ensures that the test will be carried out reliably. Performing a tightness test helps prevent unpleasant incidents such as leaks or installation failures.
What pumps are used during pressure tests?
Installation pressure tests are performed using test pumps. Dambat offers high-quality IBO pressure test pumps with manual control—the PR50—and electric control—the PR Auto. The manual pump offers an operating pressure of 5 MPa, 50 bar, 50 kg/cm². It is also equipped with a 12 L tank. The main advantages of manual pumps are their compact size, ease of use, and low price. Although the electrically controlled pump is more expensive and heavier than the manual model, it provides greater operating comfort. It also offers better technical parameters. In this case, you can expect an operating pressure of 6 MPa, 60 bar, 60 kg/cm² and a flow rate of 174 L/min.
Dambat's pressure test pumps perform their function perfectly. They are characterized by high pumping capacity, achieved through a long stroke, and the ability to adjust the pressure precisely, enabled by a short stroke. They are therefore an excellent choice for installers, construction companies, and companies specializing in installation tightness testing.
