When installing a mechanical shaft seal, it is critical to ensure the correct spring pressure is applied to the seating faces. This allows the seal to properly seat and creates the necessary seal between the pump shaft and the housing. Applying the proper spring pressure helps prevent leaks and ensures the long-term reliability of the mechanical seal.

B) Polishing the seating faces with emery cloth is not necessary and can actually create uneven surfaces.
C) Final spring collar adjustments should be made with the pump stationary, not running.
