STUFFING BOX PRESSURE S097
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
