Over the years, Kalsi Engineering has performed many tests directed at rotary control device (RCD) sealing. When we first came up with the concept for the now-patented floating metal backup ring, we did our initial testing in a test fixture with a 2.75” (69.85mm) shaft, so that we could get quick, economical feedback on rotary seal performance and hardware

Consulting Engineering Services
Kalsi Engineering, Inc., a high technology firm, was founded in 1978 to provide consulting engineering services in the areas of research and development, design, analysis, and testing of mechanical equipment and structures. Our facilities are located in Sugar Land, Texas, approximately 17 miles from downtown Houston and easily accessible from the airports.
Kalsi Engineering has a diversified client base that includes equipment manufacturers, oilfield service companies, petrochemical plants, nuclear power plants, aerospace engineering companies, architect/engineers, industry research organizations, and government agencies. In addition to serving individual clients, we have successfully completed many joint-industry group-sponsored projects.
In addition to providing consulting engineering services, Kalsi Engineering offers rotary seal and software product lines that were originally developed to solve difficult problems associated with energy production. Our patented rotary seals are the result of our pioneering research in hydrodynamic lubrication.
Our suite of engineering software began with JarPro™ jarring analysis software, which is used to reduce the costs associated with a stuck drillstring by optimizing jarring tool placement. KVAP™, CVAP™ and LiFE™ are state-of-the art software applications that are widely used to evaluate critical valve and actuator issues in nuclear power plants.
Traditional Kalsi Seals require the lubricant pressure to be balanced to or higher than the environment pressure. The revolutionary BDRP™ Rotary Shaft Seals were developed for applications where the pressure of the seal lubricant may be up to 1,000 psi (6.89 MPa) less than the pressure on the opposite side of the seal. The ability to handle pressure in either direction and significant speed makes the BDRP a good candidate as a hydraulic swivel or rotating control device (RCD) seal.
KLS® spring-loaded lip seals are used to retain a pressurized non-abrasive fluid. They were designed and successfully tested for service conditions where the pressure acting from the spring side of the seal is up to 1,000 psi greater than the pressure of the seal lubricant. This performance is the result of hydrodynamic interfacial lubrication that is provided by a patented wave geometry on the low pressure end of the seal.
The patented floating backup ring arrangements are axially force balanced, and radially pressure balanced. These features allow the smallest practical extrusion gap to be used, while accommodating shaft runout and misalignment. By minimizing the extrusion gap, the rotary seals can seal higher pressures for longer periods of time. Floating backup rings are applicable to many types of equipment, including rotating control devices (RCD), oilfield washpipe assemblies, sideport swivels and hydraulic swivels.
A rotating control device (RCD) reduces formation damage in oilwell drilling by maintaining the pressure of the annular fluid column of drilling mud at a pressure below, or comparable to, that of the reservoir. Early versions of Kalsi-brand rotary seals began to be used in RCDs in 1991. Since then, several advances in technology enable our seals to operate in more adverse RCD sealing conditions, including higher pressure, higher speed, less cooling, lower viscosity lubricants, and less complicated lubricant supplies.
