How to fill the pump seal white oil?

Question: How to fill the pump seal white oil? What machinery? Should the pressure regulator be pressurized before refueling or after? Thank you for the reply!
Most mechanical seal systems are equipped with a manual oil injection pump
Open the accumulator inlet using an oil can or a hand-cranked pump. After adding white oil, use the built-in manual pressure pump to apply pressure
Generally, a manual pressure pump is used to fill the isolation fluid; for the 53B bladder-type accumulator, the bladder should be pressurized first before the isolation fluid is added. There is a specialized tool for pressurizing the bladder, using nitrogen gas for this purpose.
Based on the information you provided, it should be the 53B system. 1. First, the accumulator needs to be pressurized; there are specialized tools for this purpose, and nitrogen cylinders are used to pressurize the accumulator. The sealing supplier will specify the pre-charge pressure for the accumulator ； 2. Next, fill the seal with an isolation fluid (i.e., the white oil you mentioned). There is usually a manual refilling pump on the sealing system; it takes a long time to fill it for the first time, as the seal chamber and pipelines need to be completely filled. As time goes by, more force is required to carry out the filling process, since the pre-charge pressure of the accumulator has to be overcome ； There are pressure gauges or pressure transmitters on the 3.53B system pipelines; the sealing supplier will specify a certain pressure, and it is sufficient to fill the system to that pressure ；
