Kalsi Seals Handbook
This handbook includes rotary seal implementation and troubleshooting guidelines, with a special emphasis on oilfield sealing applications. It is based on the collective wisdom of our senior staff members, who have many decades of experience in solving various seal implementation challenges. It is a valuable design manual for existing customers, and for individuals who are interested in using our rotary seals.
Rotary Seal Literature
A seal that facilitates the use of thinner lubricants and higher pressures and speeds, at the expense of greater hydrodynamic leakage. Applicable to surface equipment such as rotating drilling heads/ bop’s and high pressure hydraulic swivels.
The axially constrained seal provides improved abrasion resistance in applications having little or no differential pressure. Available for radial gland depths of 0.250” and 0.309”. Widely used as an oilfield mud motor balancing piston seal.
The wide footprint seal is a new generation Kalsi Seal for retaining pressurized lubricants. Key enhancements include improved environmental exclusion, increased lip width and increased compression.
This four page brochure provides a brief overview of Kalsi Engineering and Kalsi rotary shaft seals, which are used in drilling mud motors, oilfield rotary steerable tools, high pressure coring swivels, and other abrasive service equipment.
A composite FKM/TFEP rotary seal construction for high temperature service in applications with low and medium pressure differential, such as the rotary steerable tools used in oil well drilling.
A pump seal cartridge that provides improved reliability and longer life in oilfield well cementing service. The rotary seals hydroplane on a film of oil to reduce seal-generated heat. A special purpose seal serves as a pump that flushes a pair of lip seals.
A seal that combines enhanced lubrication and zigzag waves to extend performance over more conventional seals. The Hybrid Seal be designed for performance ranging from that of the Wide Footprint Seal to the Enhanced Lubrication Seal.
This brochure outlines recommended practices for using Kalsi-brand swivel seals in multi-circuit high pressure hydraulic swivels.
An optional surface treatment reduces the breakout torque of HNBR seals. This treatment was developed for applications that are sensitive to breakout torque, such as underwater vehicles, oilfield rotary steerable tools, and rotary control devices.
A soft integral energizer significantly reduces seal-to-shaft contact pressure, breakout torque, and running torque.
Kalsi Seals are used in various severe service rock cutting applications, such as mining, coring, utility drilling, and well drilling. Seals with extra wide dynamic lips are now available to provide a significant increase in sacrificial material.
This 2016 paper describes advancements in high pressure rotary sealing, including test results at a PV of 1.89 million.
