WebAt the maximum head (circled in red), the pump has zero flow or little. This is often referred to as the shut-off head. When looking for a pump, ensure that the head provides a sufficient flow rate. For example, if you require the pump to operate at 180m³/h (780USGPM), the maximum head would be 26m (86ft.) WebThe total head is the sum of the static head (remember that the static head can be positive or negative) and the friction head. 5. Select the pump. You can select the pump based on the pump manufacturer’s catalogue information using the total head and flow required as well as suitability to the application. breakaway chelsea mi
