Stuffing Box Pressure

The pressure in the stuffing box is somewhere between suction and discharge pressure, but closer to suction pressure.

The general formula for stuffing box pressure in a single stage, end suction, centrifugal pump is:

As an example:

  • Discharge pressure = 50 psi
  • Suction pressure = 10 psi

Stuffing box pressure = (50-10) / 4 +10 = 20 psi
