What is the 'rule of thumb' regarding pump packing?

Replace packing rings once a month
Use as many rings as possible for efficiency
Never put rings of new packing over the old packing
Always add lubricant to the packing before use

The correct answer is: Never put rings of new packing over the old packing

The 'rule of thumb' regarding pump packing is to never put rings of new packing over the old packing. This practice is critical for maintaining the efficiency and functionality of the pump system. If new packing rings are added over old ones, it can lead to improper sealing and increased wear on both the new and old packing materials. This accumulation can encourage leaks, increase maintenance requirements, and reduce the overall longevity of the pump. When properly maintaining pump packing, it is essential to ensure that the packing area is clean and that old packing is fully removed before new packing is installed. This allows the new packing rings to seat correctly, creating a better seal and ensuring optimal pump operation. Proper maintenance and attention to this rule can prevent costly repairs and downtime associated with pump failure or inefficiencies in the system.
