WebAug 1, 2024 · When flow data are not available, operators can use the following five ways to try and determine a pump operating point. 1. Measure total dynamic head. Total dynamic head (TDH) is total head developed across the pump centerline reference for a given set of conditions (pump speed, impeller diameter, etc.). WebThe performance of the pump at a certain speed (RPM) can be found in the manufacturer’s datasheet displayed as the flow rate (Q) versus head curve (figure 2). At 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 ...

WebExample: A pump with a max. pressure head of 8 bar (80 metres) will actually run at 18 bar if the NPSH A is 10 bar. i.e.: 8 bar (pump curve) plus 10 bar NPSH A = 18 bar. This … WebThe relationship between the flow and pressure (head) developed by a pump is graphically represented by a pump curve. A pump curve shows all of the operating points of a …
