  • Sealing method, new seal for components of fluid transfer systems, especially tubes, and their applications, especially in pumps and circuits for special fluids
    Patent number: 6517076
    Abstract: The invention concerns a new seal system for resolving the problem of the contamination of special fluids carried in pumps and moreover providing improved sealing by virtue of its special geometry and design. According to the invention, one of the elements to be connected can replace the seal owing to the fact that the seal system includes a combination of two elements to be connected with a fine film ring, one of the elements to be connected having a geometry able to effect a double indentation on the film ring. The invention may be used in pumps and circuits for fluids of the semiconductor industry. The three elements of the seal system, including the pump body, tube, and film ring, may be made of PFA.
