Recently, we procured a John Crane Mechanical Seal Type 606 as a replacement part for pumps. However, upon inspection, we noticed that it was stamped as type 605 on the shell (Rotary Seal Assembly near the face). Additionally, the Rotary Seal Assembly's color is brown instead of the standard stainless steel silver color, while the Compression Ring remains the typical stainless steel silver color. This discrepancy has raised questions about the authenticity of the seal—is it truly the original John Crane Type 606 or an outdated Type 605? Your assistance in clarifying this issue would be greatly appreciated. Thank you.
Have you inquired with the supplier about this product?
quote by Danny Harvey: Have you inquired with the supplier? Such a novel idea!
The supplier claimed that their product was original, but they were offering it at a significantly lower price than Johne Cran's. This competitive pricing makes it a great deal for customers searching for quality products at affordable rates.
If you need further guidance, I recommend consulting with John Crane for assistance.
Is there a material certification provided by the supplier?
It's important to make sure the correct mechanical seal is being used, especially when you're dealing with something as significant as pump machinery. If I can suggest, you might want to get in touch directly with a contact at John Crane. Their team should be able to check the serial number and verify if it's indeed a Type 606 or not. The color difference could be due to a variety of reasons, like a change in manufacturing processes or materials. I wouldn't solely rely on the color to determine authenticity. Reach out to their team—they're typically good about helping with these sorts of queries.
That's an interesting concern you've raised. While I'm not an expert on John Crane Mechanical Seals, typically, different types (like 605 vs 606) refer to different design specifications, which would include color and stamping. However, it's also possible that the distinction is coming from a manufacturing error or simply due to differentiation in production batches. I would definitely recommend reaching out to John Crane's customer service or your supplier for a detailed explanation, as they would be able to provide the most accurate information. Just to cover all bases, I'd also suggest verifying authenticity by checking for authenticity markings, which might also include barcodes, holograms, or unique serial numbers.
While it's possibly a mislabeling issue, the color discrepancy you mentioned does raise some eyebrows. Genuine John Crane seals typically maintain consistent coloration across parts. Furthermore, there can be functional differences between seal types, so using type 605 instead of 606 might lead to unexpected problems or poor performance even though they appear similar. I would suggest reaching out directly to the supplier or John Crane customer service to clarify the issue. They should be able to resolve your concerns about authenticity and make sure the seal meets your requirements.
