Mechanical seals are undoubtedly a critical component of industrial machinery and equipment. However, most manufacturers fail to identify where they’re located before repairing or replacing them. While mechanical seal repairs and replacements require the same process, it’s essential to take the right steps to identify the seal instead of looking at the pump, compressor, or impellers.
With the right mechanical sealing solutions, you’ll never have to worry about working with the wrong mechanic seals. If you’re new to this process, here are the three key steps to take when trying to identify a mechanical seal.
Find the Part Numbers
One of the most straightforward ways to pinpoint a mechanical seal in an industrial device is by looking at the part numbers. These are short descriptions of a piece of equipment placed on a mechanical seal, highlighting details like the mechanical seal’s metallurgy, elastomer, and seal face type.
Most renowned machine manufacturers and designers always place part numbers of machines before shipping them off. However, there’s also a chance you might not find these part numbers at all. In such cases, start by finding the elastomer by looking for a rubber component. This will give you a better idea of the mechanical seal’s overall compatibility with the machine and its quality.
Look at the Seal Faces
Once you’ve successfully pointed out the mechanical seal’s elastomer, the next step is to determine what kind of seal face the machine has. This process is a lot easier than others, especially if you’re good with others. Keep the following factors in mind:
- Ceramic mechanical seals have white seal faces.
- Metallic mechanical seals have bronze and brassy colors.
- Silicon mechanical seals are usually lightweight and gray.
- Tungsten carbide mechanic seals are heavier and gray.
- Carbon mechanical seals have black seal faces.
Determine the Metallurgy
The last step is determining the metallurgy. This will help you instantly determine where the mechanical seal is located. Most models are manufactured with stainless bronze and brass materials. These are for conventional industrial applications.
However, if you find Monel as a construction material in your seal, you’ll know that it’s better suited for marine applications. Similarly, a seal designed for use in high temperatures will usually be made with Hastelloy.
