When pump packing fails, the results can be far reaching and devastating. Failure in packing can damage the pump, cause pump failure and emergency or unscheduled plant shutdowns besides the needed clean-up effort due to possible spillage. Because pump failures are the leading causes of pump downtime in most setups, it is important to consider steps that go towards ensuring the integrity of your pump packing.

For the majority of pumps, compression packing provides the best return on your initial investment when it comes to product service life benefits, leakage control, and dependability. Compression pump packing has been in use for a long time and remains the most extensively used method for equipment that requires prevention of process fluids loss.
The original packing materials of choice were the flexible, soft types. These are still widely used largely due to their easy installation, low upfront cost, and ready availability. However, it’s important to note that over time, it could become an extremely expensive venture as they will need more maintenance. They in addition allow more product fluid loss compared to mechanical seals.
Mechanical materials can save considerable time for maintenance of people and money as well. However, this is only possible if they’re correctly installed and properly taken care of.
Durability of the pump is a very vital consideration. Ensure that the packing chosen is not only strong but also long-lasting. Avoid going for the lowest-cost alternative pump packing. It pays to bear in mind that the packing cost is insignificant when pitted against the cost of packing failure or repacking. The actual real savings you get from a longer-lasting pump are going to be many times more than what it cost to pay for durable pump packing.
Ease of Removal
It is vital to avoid packings that tend to harden, leaving behind residue or those that are likely to score the pump shaft sleeves. Using a non-abrasive and non-hardening packing is always recommended as it becomes easy to remove just as the installation was.
While more advanced pump sealing and packing solutions are now becoming widespread, such as mechanical seals, compression still holds its place as an important technique in the sector. The packing’s available today come in a broad variety of options, with something for just about every pump application. The pump packing arrangement that you select needs to meet the desired product reliability, life cycle costs, and the pump application.
