The performance of a submersible pump is typically evaluated using specific parameters that directly impact its efficiency and effectiveness. Unlike factors such as its weight or noise level, which may have some relevance in other contexts, the primary criteria for assessing a submersible pump's performance focus on its operational capabilities. These include the head and flow rate, which are critical in determining how well the pump can move fluids and at what pressure. Therefore, understanding these parameters is essential for selecting the right pump for specific applications.
