Stuffing Box Pressure - Quick Calc
Stuffing Box Pressure - Quick Calc
(OP)
Hello
To get the box pressure I have used a quick calc
************************************
Suction + 1/3 Differential = Box
(Dis - Suction) = Diff
NB - With Balance Holes
*************************************
I have a pump where there is NO BALANCE HOLES in the impeller and would like to est. box pressure
Is there a similar quick calc to get this ??
TIA

RE: Stuffing Box Pressure - Quick Calc
The equation in the other email is good. But if your impeller has pumpout vanes on the backside or the pump has an expeller behind the impeller, the stuffing box pressure will be greatly reduced. This will vary by manufacturer.
