      This specific size (99.5 mm x 3 mm) is used on the Edwards E1/E2M pump family . This includes the following pump models:

      • E1M18

      • E2M18

      These are single and two-stage rotary vane pumps used in laboratories and industrial applications. If you own or service these pumps, this is a seal you should keep in your spare parts box. As the product description notes, its “primary role is to ensure a tight and reliable seal within these pump models, preventing leaks and maintaining the proper functioning of the equipment” .
