Despite the fact that seals are a part of our everyday life, many people don’t notice their value. No matter if you are a beginner or an expert, finding the right seal for your project can be confusing. There are two main types of sealants you’ll need to choose from: mechanical seals or packing seals. This will all depend on your unique project. Below you will find a pump sealing basic guide so you can decide which one is right for you.

Pump Sealing Basic Guide

Packing Seals

Packing seals are the most common and widely used sealing solution. They use rope-like materials that wrap around the shaft of a pump. This fills the dead space and reduces fluid loss. In most cases, packing seals are the top choice for rotating equipment applications. It has a wide variety of benefits and can help make your job a lot easier in the short- and long term. Consider the following benefits of packing seals the next time you need to determine your seal options.

• Cost-Effective: Unlike mechanical seals, packing seals are most cost-effective. They have lower up-front costs and it is cheaper in the long run if they are properly taken care of.
• Smooth Installation: The ease of installation and the total turnaround time for packing seals is fast and efficient. This not only saves you time, but also money. The installation of packing seals does not require the decoupling of the drive shaft. This is a major advantage as compared to certain mechanical seals.
• Low Maintenance: Packing seals are less complex in regard to maintaining the equipment and the related inventory.
• Durable: Unlike mechanical seals, packing seals can withstand radial movement and misalignment much more effectively. For machinery that is frequently moved axially, packing seals are the best option. Packing seals are just much more forgiving compared to other sealants.
• Versatile: Packing seals can effectively operate on machinery that is in average to good condition. This is unlike mechanical seals as they require the machinery to be in good condition and operate reliably.

Mechanical Seals

While there are major benefits to packing seals, mechanical seals are also an effective seal option. A mechanical seal is just like a packing seal in the sense that it is used to provide a seal at the entry and exit points of a rotating shaft. The seal itself often has flat faces that allow the shaft to turn while maintaining the seal. It is very difficult for leakage to occur with mechanical seals if they are installed properly. Consider the following benefits the next time you need to figure out which seal is right for your project.

• Safety: If you have a substance that absolutely cannot leak due to safety or environmental issues, it’s important to go with a mechanical seal. One of the major benefits of mechanical seals is their effectiveness in terms of safety.
• Low Repair Costs: Mechanical seals are more expensive as compared to alternatives. However, their repair costs are low as they do not require a lot of maintenance. As long as they arrive installed effectively they can prove a great long-term investment. There is less wear and tear due to their effectiveness which reduces the need for replacement.
• Specialized Equipment: For unique and specialized equipment, mechanical seals are preferred. They are designed to withstand much more in terms of durability as compared to other options.
