Kalsi Engineering provides <<seo term>> for use in our patented Kalsi-brand rotary shaft seal technology.
<<seo term>> used in Kalsi Seals are for service across a wide range of pressures and speeds, in abrasive and non-abrasive environments.
Kalsi Seals are a family of patented, one-piece rotary seal designs that provide hydrodynamic lubrication to minimize seal and shaft wear, and that accommodate high differential pressure. They are used for lubricant retention and contaminant exclusion. They were originally developed for the harsh and unforgiving oilfield downhole drilling environment and provide an effective solution to the severe service conditions found in many industries.
Kalsi Seals are installed in a housing groove and are radially compressed against a shaft. They seal statically in the same manner as other interference-type seal designs, such as O-rings. The dynamic sealing lip incorporates a wavy hydrodynamic edge on the lubricant side, and a circular exclusionary edge on the environment side. When rotation occurs, a thin lubricant film is hydrodynamically wedged into the seal-to-shaft interface by the waves. This enables higher pressure and speed combinations and longer life because the lubricating film significantly reduces wear and heat associated with dry rubbing that is typical with conventional interference-type seals. When rotation stops, the hydrodynamic lubricating action stops, and static sealing is reestablished.
