Aseal is a device or material that helps join systems, mechanisms or other materials together by preventingleakage (e.g. in apumping system), containingpressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case ofsealants and compression in the case ofgaskets. Seals are installed in pumps in a wide range of industries including chemicals, water supply, paper production, food processing and many other applications.[1]
A stationary seal may also be referred to as a 'packing'.
Bodok seal, a specialized gas sealing washer for medical applications
Bonded seal, also known asDowty seal or Dowty washer. A type ofwasher with integralgasket, widely used to provide a seal at the entry point of a screw or bolt[2][3]
Bridgman seal, a piston sealing mechanism that creates a high pressure reservoir from a lower pressure source
Split seals[4] are innovative sealing solutions designed to enhance efficiency and convenience in various mechanical systems. These seals are specifically engineered to address the challenges associated with traditional seals, offering improved installation, maintenance, and operational benefits.
Inflatable seal Seals that inflate and deflate in three basic directions of operation: the axial direction, the radial-in direction, and the radial-out direction. Each of these inflation directions has their own set of performance parameters formeasurements such as the height of inflation and the center-line bend radius that the seal can negotiate. Inflatable seals can be used for numerous applications with difficult sealing issues.
Labyrinth seal A seal which creates a tortuous path for the liquid to flow through
