Under the condition of no fluid at the inlet, what pressure can the white oil in the sealing system of the centrifugal pump 53B achieve? In other words, should the white oil pressure be considered based on the operating pressure or the design pressure?
It is generally about 1.5 kilograms higher in pressure than that of the sealed chamber
It should be about 0.1-0.2 MPa higher than the pressure in the sealed chamber; the pressure value for the sealed chamber can be obtained from the pump manufacturer.
