Should nitrogen pressure be applied to the sealing oil tank when a high-speed pump is used as a backup?

It is necessary; the sealing pressure of the mechanical seal depends on the pump inlet pressure, so the standby pump needs to be pressurized.

Should the pressure be increased to the normal operating nitrogen pressure, or just a slight increase?

It’s sufficient to be 0.2-0.3 MPa higher than the inlet pressure
