Specify Fluid Data and Net Positive Suction Head Available (NPSHa)

• If the NPSHa is a known value, enter it directly.

• Or, use the NPSHa calculator feature to calculate an NPSHa value.

• You can also calculate the NPSHa using PUMP-FLO’s Total Head Calculator.

• Specify a margin ratio factor to be applied to the pump’s NPSHr value. PUMP-FLO checks that the NPSHa is greater than the pump’s NPSHR multiplied by the margin ratio. (The margin ratio is optional.)

• Choose from a list of 140 fluids.
