How tight should the packing be adjusted on a pump?

When adjusting the packing on a pump, it's essential to find a balance that ensures both effective sealing and proper lubrication. The recommendation to adjust packing to 1 drip per second strikes this balance.

This rate allows enough leakage for the packing to remain lubricated and cool, reducing wear on both the packing and the shaft. If the packing is too tight, it can cause overheating and premature failure, as well as increase the power required to operate the pump. On the other hand, too much leakage can lead to inefficiencies and loss of fluid.

By aiming for a rate of 1 drip per second, operators can ensure that the packing provides adequate sealing while minimizing wear and maintaining pump efficiency. This method helps prevent significant leakage while ensuring that the packing is not overly constrictive, thus promoting the longevity and functionality of the pump system.
