3. Tips to Choose Industrial Seals Manufacturers & Suppliers for the Water Treatment Industry
Accordingly, the selection of the manufacturers of industrial seals involves entering a totally different mindset compared to other industries. As mentioned above, the functionality of the seals used in water treatment systems is heavily influenced by the lifespan of the materials, as well as the long service life.
(1) Chemical and media compatibility shall be the priority
Seals may be exposed to chlorinated compounds, ozone, acids, alkalis, and other chemical treatment agents used in water treatment systems. Instead of asking the supplier for temperature and pressure limits, consider asking if they have experience in material selection for EPDM, FKM, PTFE, etc., in chemically treated water treatment systems and can provide long-term aging testing, swelling data, etc.
(2) Consider Lifecycle Cost, Not Just Unit Price
The cost associated with shutdowns in water treatment plants can be substantial. There is potential for a seal that may be a bit more expensive but would give longer life and greater compressive set resistance. Suppliers with performance information and life cycle cost comparisons available would be more valuable.
(3) Assessment of Stability during Continuous Operation
Unlike intermittent running industrial systems, the systems in the treatment plant using water operate on a continuous basis, described by the 24/7 system. The product should therefore possess the ability to be elastic and seal in the constant running condition. Hence, companies that provide the results of product use under continuous running are better suppliers.
(4) Assess Clean Manufacturing and Compliance
Many applications in water treatment, particularly potable water systems, require adherence to drinking water standards. Seek out manufacturers with experience and knowledge of certifications and traceability requirements specific to either municipal or industrial water systems.
(5) Look for Custom Engineering Support
Water treatment equipment may use large diameter seals, flange gaskets, and non-standard profiles; companies offering rapid prototyping and design consultation may be highly beneficial in the optimization of seal performance in pumps, valves, membranes, and filters.
Buyers can determine the true sealing partners in water treatment environments by focusing on such points as chemical compatibility, lifecycle value, operational stability, compliance, and depth of engineering.
4. Conclusion
As mentioned above, all 10 Industrial Seals Manufacturers and Suppliers are excellent examples of water treatment sealing industry companies. Their superior technology and quality control processes, coupled with their customer-centric solutions, have enabled them to stay abreast of innovation in local and industrial water treatment systems. Using any of these companies as a supplier for your needs will ensure you not only maintain efficient running operations but also keep your costs lower than they could be.
