Enter the suction pressure (Pa) and the design pressure (Pa) into the calculator to determine the Pump Discharge Pressure. 

Pump Discharge Pressure Formula

The following formula is used to calculate the Pump Discharge Pressure. 

Ppump = Ps + Pd

  • Where Ppump is the Pump Discharge Pressure (Pa)
  • Ps is the suction pressure (Pa) 
  • Pd is the design pressure (Pa) 

How to Calculate Pump Discharge Pressure?

The following two example problems outline how to calculate the Pump Discharge Pressure.

Example Problem #1:

  1. First, determine the suction pressure (Pa). In this example, the suction pressure (Pa) is given as 54.
  2. Next, determine the design pressure (Pa). For this problem, the design pressure (Pa) is given as 15.
  3. Finally, calculate the Pump Discharge Pressure using the equation above: 

Ppump = Ps + Pd

Inserting the values from above and solving the equation: 

Ppump = 54 + 15 = 69 (Pa)


Example Problem #2: 

Using the same process as above, first define the variables required by the formula. In this case, these values are:

suction pressure (Pa) = 95

design pressure (Pa) = 189

Entering these values yields:

Ppump = 95 + 189 = 284 (Pa)
