2. Swimming pool sanitation - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool_sanitation

   Water is forced through a filter and then returned to the pool. Using a water pump by itself is often not sufficient to completely sanitize a pool. Commercial and public pool pumps usually run 24 hours a day for the entire operating season of the pool. Residential pool pumps are typically run for 4 hours per day in winter (when the pool is not ...

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 ...

4. EPDM rubber - Wikipedia

   en.wikipedia.org/wiki/EPDM_rubber

   A common use is in vehicles, where EPDM is used for door seals, window seals, trunk seals, and sometimes hood seals. [11] Other uses in vehicles include wiper blades, [ 12 ] cooling system circuit hoses; water pumps, thermostats, EGR valves, EGR coolers, heaters, oil coolers, radiators, and degas bottles are connected with EPDM hoses.

5. Labyrinth seal - Wikipedia

   en.wikipedia.org/wiki/Labyrinth_seal

   Indeed, many gas turbine engine seals leak by design. [4] Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some ...

7. Hydrodynamic seal - Wikipedia

   en.wikipedia.org/wiki/Hydrodynamic_seal

   A hydrodynamic seal is a type of mechanical seal. A hydrodynamic seal uses a dynamic rotor with grooves that act as a pump and create an air film that the opposing sealing surface will ride on. A hydrodynamic seal performs better than hydrostatic seals by providing greater film stiffness, lower leakage and lower lift off speeds.
