After determining the type of water pump, its economic performance should be considered, and special attention should be paid to the selection of the pump's head and flow and its supporting power. It must be noted that the head (total head) indicated on the pump label is different from the discharge head (actual head) during use. This is because there will be a certain resistance loss when the water flows through the water pipe and the vicinity of the pipeline. Therefore, the actual head is generally 10% to 20% lower than the total head, and the water output is also reduced accordingly.
