What component does the seal piping obtain liquid from in a pump system?

The seal piping in a pump system is designed to obtain liquid from the discharge side of the pump. This connection is crucial as it helps maintain the mechanical seal's integrity by supplying a sufficient amount of liquid to cool and lubricate the seal. The sealing chamber requires fluid under pressure to prevent leakage of the pumped fluid, and drawing from the discharge side ensures that this necessary liquid is both available and at the appropriate pressure to keep the seal operational.

In contrast, if the seal piping were to draw from the inlet side of the pump, the pressure might not be adequate to ensure proper sealing, potentially leading to leakage. Drawing from the sealing chamber or lubrication reservoir wouldn't provide the necessary pressure or volume needed for proper sealing in the mechanical seal's operation and could also interfere with the sealing function. Thus, obtaining liquid from the discharge side of the pump is the optimal approach for maintaining effective seal performance.
