What type of pump is normally used when hydro testing?

In the context of hydro testing, a single acting positive displacement pump, such as a Baker pump, is commonly used due to its ability to generate the high pressure necessary for testing the integrity of piping systems. This type of pump operates by moving a fixed volume of fluid with each stroke, ensuring a consistent flow rate and the capability to produce significant pressure. This is particularly important in hydro testing, where it is essential to exert enough pressure to identify leaks or weaknesses in piping systems.

The fixed displacement nature of single acting positive displacement pumps provides precise control over the volume of fluid being pumped, which is vital during testing to avoid exceeding pressures that could lead to equipment failure or unsafe conditions. Furthermore, these pumps can handle a wide range of fluids, making them versatile for various testing applications.

While other types of pumps, such as centrifugal or diaphragm pumps, have their specific applications, they may not deliver the same level of pressure consistency or control required for effective hydro testing.
