Frequently Asked Questions

Here, you can find answers to your most common questions about the repair process, the most common problems, and how we handle each case at SERIMAN. If you have a more specific question, our technical team is available to assist you.

  • What are the most common problems in diaphragm seals?

    The most common cases are dented diaphragms, loss of filling liquid, material corrosion, and damage to capillaries or gaskets. All these problems affect measurement accuracy and require specialized intervention.

  • What should I do if the diaphragm is dented or damaged?

    A dented or punctured diaphragm does not provide correct readings. The solution is to replace it with a new one. Contact our technical service.

  • How does corrosion affect the diaphragm?

    Aggressive processes can corrode the diaphragm material and the wetted parts. That’s why it is essential to choose the right material (Hastelloy, tantalum, etc.). If corrosion is severe, it may also be necessary to replace the flange.

  • How long does it take to repair a diaphragm seal?

    The standard lead time is 14 days from order receipt. In urgent cases, we can provide express service in just 48 hours after order confirmation.

  • Can any type of diaphragm seal be repaired?

    Yes, we work with all kinds of materials (stainless steel, Hastelloy, tantalum, Monel, etc.) and market brands. We adapt the repair to the process needs and customer specifications.

  • What documentation is provided after the repair?

    We always deliver a detailed technical report with all equipment data, tests performed, and the warranty of the work.

  • Can I request equipment pickup at my facilities?

    Yes, we arrange pickup at your plant or workshop, so you don’t lose time on logistics or travel.

  • Is it cost-effective to repair instead of buying a new device?

    It means savings and reduces waiting times compared to acquiring completely new equipment.
