Gear pump head & flow rates
WebSep 11, 2024 · In this article we learn how to perform pump calculations in both imperial and metric units to assess pumping performance following the change of flow rate, pump speed, head pressure and power. These formulas are common practice rules of thumb and provide theoretical values to which actual values will likely differ. YouTube video tutorial … 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 ...
