When packing is improperly installed on a reciprocating pump, it can lead to increased friction between the packing and the pump shaft. This friction occurs because the packing may not be making proper contact, which can result in the shaft experiencing resistance. Consequently, the shaft will have difficulty turning freely, which may cause operational issues within the pump system.

Improper packing installation can create a misalignment between the shaft and the packing box, exacerbating this effect. As the shaft struggles to turn, it can also lead to excessive wear on both the packing and the shaft, potentially leading to further complications and maintenance requirements. While other options may suggest different outcomes, they do not accurately reflect the immediate mechanical consequences of improper packing installation.
