What is a critical measure to take to avoid pumping efficiency loss?

Minimizing hose bends is critical to maintaining pumping efficiency because bends can create turbulence and resistance in the flow of fluid. When a hose is bent, the fluid must navigate through tighter spaces, which can impede its movement and lead to significant energy losses. Each bend in the hose can contribute to friction losses, making it harder for the pump to move the fluid effectively. This not only results in a decrease in flow rate but can also cause the pump to work harder, potentially leading to increased wear and energy consumption.

In contrast, using a smaller discharge hose can lead to increased friction loss and reduced flow capacity. Reducing intake head may not be practical or effective in improving overall efficiency and could depend on other system variables. Increasing pump speed does not always directly translate to enhanced efficiency, as it may lead to cavitation and additional stresses on the pump and piping system. Therefore, minimizing bends in the hose is a straightforward and effective measure to ensure better performance and efficiency in pumping systems.
