Kalsi Engineering introduces KLS™ high pressure lip seals for rotary service
Kalsi Engineering introduces KLS™ high pressure lip seals for rotary service

Houston, Texas (PRWEB) March 30, 2016 -- Sugar Land-based Kalsi Engineering, an industry-leading consulting engineering firm and manufacturer of rotary seals for the oil and gas industry, has recently introduced its latest seal technology, the KLS series high pressure lip seal.

KLS lip seals are spring-loaded and can seal fluid pressures of up to 1000 PSI ( 6.89 MPa) when used in applications that feature unidirectional rotation, and have undergone extensive testing at rotational speeds of 543 feet per minute (2.76 M/S).

"For applications in which clean pressurized fluids must be retained, only one KLS seal is necessary, and it can be lubricated with a simple unpressurized lubrication system." -- John Schroeder, Kalsi Seal Global Business Development Manager

Post this

The ability to maintain a seal at such a high pressure differential is due to the unique construction of the KLS lip seals. They are made from a combination of extrusion-resistant plastic and elastomer. They incorporate a patented wave geometry that provides hydrodynamic interfacial lubrication from the low pressure side of the seal. Without the efficient lubrication of the dynamic sealing interface provided by the wave technology, similar seals with the same cross-sectional profile fail within hours at a much lower pressure of 500 PSI. Initial loading of the dynamic lip against the shaft is provided by a V-shaped spring.

"For applications in which clean pressurized fluids must be retained, only one KLS seal is necessary, and it can be lubricated with a simple unpressurized lubrication system," said John Schroeder, Kalsi Seal Global Business Development Manager. For example, the unpressurized bearing lubricant. In applications where abrasive fluids such as drilling fluid are retained, two seals are required, because the ability of lip seals to exclude abrasives decreases as the differential pressure increases. A lubricant is provided between the seals, and pressure balanced to the abrasive fluid. This arrangement protects both seals from damage by isolating the outboard seal from differential pressure and isolating the inboard seal from abrasives.

In addition to KLS high pressure lip seals, Kalsi Engineering also produces a variety of other seal designs that are tailored to specific service conditions, such as extreme pressure lubricant retention, abrasive exclusion, and low viscosity lubricants.

Kalsi seals are used in a variety of equipment for the oil and gas industry, including rotating control devices, hydraulic swivels, sealed bearing mud motors, and rotary steerable drilling tools. . They can also be found in other types of equipment, such as dredge pumps, submersible vehicles and reverse circulation drilling machines.

Kalsi Engineering was formed in 1978 to provide research, development, design, analysis and testing of mechanical components and structures. They are based in Sugar Land Texas and provide mechanical engineering solutions for many industries, including petrochemical, power generation, defense, aerospace, manufacturing and mining operations. They also manufacture hydrodynamically lubricated rotary seals, and provide predictive software to the energy industry.
