WebThis is known as the “shut-off head”, it’s the amount of head a pump can produce at zero flow. To choose your required pump, you need to know two things: the total head and what flow rate you require. As you might expect, these two quantities are related. The maximum head (shut-off head) is achieved at a flow rate of zero. 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 … t tests with python
