Stuffing Box pressure

 · TenPenny (Mechanical) 4 Apr 13 09:58. Stuffing box pressure will depend on whether the impeller has balance holes or back pumpout vanes, but if I recall correctly the general rule for an end suction single stage pump is. Pstuffbox = Psuction + 0.25 x Pdifferential. ie, suction pressure plus 1/4 of the pump differential pressure.
