WebThe NPSHa calculation would be as follows: As long as the pump’s NPSHr is less than 26.6 feet, the pump should not cavitate. However, there are some suction piping configurations that may cause the pump to cavitate even though NPSHa is greater than NPSHr. What would cause a negative pressure (vacuum) at the pump suction? WebNPSH-R and NPSH-A are not constants – they are both functions of flow (Figure 3) and also temperature. If there are any changes in capacity, it is important to reassess the NPSH margin.
