Get Price2017-3-3 · How Seals in Pumps Work? Mechanical seals are watertight fittings that are located between the fixed part of a rotating device and a shaft thus they are commonly used in pumps. It is important to stress the water-tightness of the pump. This is achieved using a fine fluid or film that is located between two friction faces to prevent the remaining fluid from passing. The film also works as a lubricant thereby reducing the wear and tear between the two lapped faces. With a mechanical seal, …

Get Price2019-8-28 · 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. The seal faces are commonly carbon, ceramic or metal. Mechanical seal applications will also incorporate an elastomer secondary seal to seal on the shaft and to seal the stationary face.
Get PriceO-Ring Mounted. ‘O’-Ring mounted mechanical seals have a small cross-section and a complete recessed ‘O’-Ring housing. A narrow seal head width allows the seals to easily fit confined DIN 24960 (EN12756) housings, whilst also providing the benefits of reduced face surface running speed, with increased circulation around the seal faces.
Get PriceWhen a pump is running fast, your seal supplier better understand what seal face combination will work, and what lubrication will be required to prevent frictional wear on the seal faces. Mechanical Seals are not all we do. Not all pumps require mechanical seals. In some cases a braided packing can prove to be less expensive to run and can ...
