2. Lapping - Wikipedia

   en.wikipedia.org/wiki/Lapping

   Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding .

3. End-face mechanical seal - Wikipedia

   en.wikipedia.org/wiki/End-face_mechanical_seal

   In mechanical engineering, an end-face mechanical seal (often shortened to mechanical seal) is a type of seal used in rotating equipment, such as pumps, mixers, blowers, and compressors. When a pump operates, the liquid could leak out of the pump between the rotating shaft and the stationary pump casing. Since the shaft rotates, preventing this ...

   en.wikipedia.org/wiki/John_Crane_Group

   From the years 1941 to 1949, Crane Packing applied for and received 24 patents, the majority of which were for mechanical seals [9] designed to handle high-pressure and corrosive applications. In 1948, Crane Packing developed its own seal face [ 6 ] lapping machines and processes, which evolved into Crane Packing’s Lapmaster division.

6. API Standard 682 - Wikipedia

   en.wikipedia.org/wiki/API_Standard_682

   API Standard 682, titled "Pumps - Shaft Sealing Systems for Centrifugal and Rotary Pumps," is the American Petroleum Institute standard for end-face mechanical seals. [1] The purpose of API 682 is to assist in the selection and operation of end face mechanical seals in centrifugal pumps. It is based on the combined knowledge and experience of ...

8. Dry gas seal - Wikipedia

   en.wikipedia.org/wiki/Dry_gas_seal

   Dry gas seals are non-contacting, dry-running mechanical face seals that consist of a mating (rotating) ring and a primary (stationary) ring. When operating, lifting geometry in the rotating ring generates a fluid-dynamic lifting force causing the stationary ring to separate and create a gap between the two rings.

9. Hydrostatic seal - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_seal

   A hydrostatic seal is a non-contacting mechanical seal that operates under an equilibrium of forces. Unlike traditional hydrodynamic seals , hydrostatic seals have two different pressure zones that are used to establish a balanced pressure zone between two seal faces. [ 1 ]
