A realistic split-scene image explaining does a centrifugal pump need priming, showing the contrast between an unprimed and a properly primed centrifugal pump in a real construction environment. On the left side, technicians wearing safety gear work on a centrifugal pump running dry, with signs of overheating and vapor caused by air trapped inside the pump casing, illustrating the risks of operating without priming. On the right side, the same centrifugal pump is fully filled with liquid and operating smoothly, delivering a steady flow of water through connected piping. The image visually demonstrates why priming is essential for centrifugal pumps to create suction, prevent cavitation, avoid dry running, and ensure reliable performance, highlighting practical field operation of RAFSUN centrifugal pump systems without any visible text.

A realistic split-scene image explaining what is the maximum height a pump can pump water, showing two different pumping methods. On the left, a surface water pump operated by a technician draws water upward from a shallow well, illustrating the suction limit caused by atmospheric pressure at approximately 33 feet. On the right, a powerful high-pressure pumping system pushes water vertically to a much greater height through industrial pipelines, demonstrating how water pumps can move water hundreds or even thousands of feet when pushing rather than sucking. The scene visually explains pump head limitations, elevation differences, and correct pump selection for high-lift applications, highlighting RAFSUN water pump technology in real-world usage without any visible text.
