Three types of mechanical seals are used in process equipment: A cartridge-mounted, end-face mechanical seal is a self-contained unit that houses the sealing components—a gland, sleeve, and hardware. A cartridge seal allows the unit to be preassembled and preset by the manufacturer.
The materials used for the seal faces and other components directly affect the sealing gap. Different materials have varying thermal expansion rates, hardness, and wear resistance properties. Proper material selection ensures that the sealing gap remains consistent and within the desired range under operating conditions.
Oct 28, 2021 · With that said, let’s look at some of the most common types of materials used in making rubber seals and the applications of each type of seal. Nitrile, or NBR, is a synthetic copolymer of acrylonitrile and butadiene, and a popular choice for seal applications requiring high oil resistance.
Feb 23, 2024 · There are two types of seals out there and the can be determined based on their anatomy. The Otariidae seals have ears that extend from the skull while the Phocidae seals don’t. Those that have ears have hind flippers that they can bury under their bodies.

Aug 28, 2019 · A mechanical seal has four components: a flat stationary seal face, a flat rotating seal face, a spring mechanism and a secondary elastomic seal. The two seal faces are pressed together by a spring mechanism.
Jan 11, 2024 · To understand how a mechanical seal works, we need to understand the basic components that make up the anatomy of any mechanical seal. Image 1 shows the cross section of two different types of mechanical seals, which show the same basic four components.
principles in mechanical seal design contribute to a working seal at the interface of the rotating shaft and stationary pump/mixer/ seal-chamber housing. Mechanical seals are usually end-face seals or rotating-face seals, but in some designs they can be circumferential or even a hybrid of lip-type seals. In either case, the following
