Leading Mechanical Seal Makers: Scale and Global Service Networks
The global mechanical seal market has several major suppliers with a wide production and service network. Knowing their scale helps users evaluate the ability to support local technical services, but scale is just one of many criteria.
Information announced by the companies
- John Crane: a network of over 200 facilities including production, sales and service, and 13 turbo service centers in more than 50 countries.
- EagleBurgmann (Freudenberg group): around 250 locations and 90 service centers worldwide.
- AESSEAL: established in 1979, according to the introduction document has over 1,750 employees and serves customers at 230 locations in 104 countries.
- Flowserve: the 2023 report mentions 35 manufacturing facilities, 131 quick response centers and approximately 193 mechanical seal models and sealing systems.
Why the service network is important
Seals often fail at the most inconvenient time. Suppliers with spare parts warehouses, repair centers and engineers near the factory help shorten downtime. For critical equipment, response time is sometimes more important than the price difference.
Criteria for evaluating seal suppliers
- Ability to provide technical support and service in your area.
- Availability of spare parts and delivery time.
- Compliance with standards such as API 682 and testing capabilities.
- Experience with your chemicals and industry.
- Training programs, failure analysis and technical documentation.
