Flat and 3D seals
Pronal inflatable seals form a tight barrier between two surfaces. Because of their high mechanical resistance, they are used for applications where a perfect seal is required.
Typical uses include:
Available either as original equipment or spare parts, they are frequently applied in or between pipes; as an annular seal; or in tubes, conduits and machinery and installations involved in the industrial, mining, mineral processing, offshore, energy and safety sectors. Examples include providing a leakproof seal between gas or liquid pipes in the oil and energy industries; plugging leaks from tanks, cisterns and pipes; sealing crushing equipment in the mineral processing industry; and to facilitate grout packing for offshore platforms or similar structures.
Sometimes referred to as doughnut seals, Pronal seals have many applications in the bulk handling industry. For example, a Pronal inflatable seal can effect an airtight dust seal around the necks of hoppers. Depending on the application, Pronal inflatable seals are made from either vulcanised fibre-reinforced synthetic rubber or polyeurethane (both reinforced or unreinforced).
One of the main benefits of Pronal seal technology to industrial and construction processes is the flexibility of the products, which:
