Titanically engineered inflatable seals

Click2Contact

The Pronal range of stock and customised, application-specific flat and 3D seals is used in many industrial applications as OEM and replacement parts for applications including sealing, pressing, gripping, handling and isolating.

The tough and highly durable seals include types suitable for equipment widely used throughout Australasia, including crushers, conveyors, hoppers, presses, vibrating equipment, silos and materials handling equipment in applications extending from powder handling, primary product and process engineering to minerals processing, power generation and pipelines and tanks.

Pronal doughnut seals technologies include:

• Weldable polyeurethane materials, with or without textile fabric reinforcing, for operating pressures up to 0.5 bar depending on application. Available in different shapes, including round, square, rectangular, hoop, gripping and fixing skirt, gripping bars and single- and multi-stage actuators and isolators.
• Vulcanised elastomer made from textile fabric coating with synthetic rubber and assembled using the vulcanisation hot curing process. Operating pressure up to 7 bar depending on application.

Pronal doughnut seals and lifting bags combine the advantages of high durability and power with gentle, precisely controlled force and expansion that can spread over broader surfaces of the object being actuated, isolated or sealed.
