The flushing fluid pressure of the pump is 1~2 atm higher than the seal chamber pressure, but how to determine the pump seal chamber pressure?

The pressure of the seal chamber must be calculated according to the form of the pump, such as a single-stage double-suction pump (split pump) type BB1, the seal chamber pressure = inlet pressure. You need to look at the location of the sealing chamber.
The seal chamber pressure of an end-suction pump is the pump inlet pressure plus one-third of the pressure difference
