Kalsi Tanged Seals were developed to prevent rotary seals from circumferentially slipping in the seal groove which can lead to premature seal failure. Rotary seals slip more often in applications […]
Rotary Seal Blog
Blogging is a way for Kalsi Engineering to provide up to date information more quickly than we can through traditional information channels like our seal handbook and static web pages. Here you will learn how we are working to solve industry problems through posts about new rotary seal products and posts about testing directed at specific industry problems and applications. You will also learn about the people who make it all happen, as we highlight the achievements and milestones in their lives. Visit our blog for the latest information on Kalsi-brand rotary seals and other Kalsi Engineering products and services.
Forrest Clay joins Kalsi Engineering in our Rotary Seal Testing Laboratory
Forrest Clay joined Kalsi Engineering’s Rotary Seals Testing Team at our Sugar Land, Texas, facility in October 2021. He is one of three laboratory technicians who set up, run, and […]
High Speed Testing of Kalsi Seals
We recently completed high-speed rotary seal testing at dredging and submersible pump conditions on two Kalsi Seal geometries. The two rotary seal geometries were selected because they can operate in […]
Sealing Advancements for Rotating Control Devices (OTC-31159-MS)
Kalsi Engineering’s new technical paper, “Sealing Advancements for Rotating Control Devices” (OTC-31159-MS), was presented at the Offshore Technology Conference in Houston, Texas last month. The authors, A. Richie and L. […]
Kalsi Tanged Seals tested at 300°F
The Kalsi Tanged Seal is excellent at excluding pressurized abrasive fluid in equipment where the seal lubricant pressure is less than the abrasive fluid pressure. We refer to this pressure […]
SBIR Topic NX19-003 Award Announcement
Engineered Integral and Downstream Flow Conditioners
In 2019, Kalsi Engineering was awarded a contract with the Department of Navy (DoN) through the Small Business Innovation Research (SBIR) program to develop and refine flow conditioners for possible […]
Another extreme high-pressure rotary seal test
Kalsi Engineering continues to perform high-pressure rotary seal tests directed at increasing the operating life of high-pressure rotary swivels. Such equipment includes washpipe assemblies, cement swivels, hydraulic swivels, rotating control […]
Early Butterfly Valve Testing with Incompressible Flow
Kalsi Engineering (KEI) conducted a water flow test program for butterfly valves for the nuclear industry as part of the EPRI Performance Prediction Methodology (PPM) between 1993 and 1994. The […]
Development and Implementation of High Flow Gate Valve Model In KVAP
Kalsi Engineering, Inc. (KEI) pioneered the development of advanced gate valve methodology that is used to account for the flow-induced forces and complex interactions between the stem and gate, gate […]
A new seal arrangement for RCDs
We have completed separate effects testing of the key components of a new rotary seal arrangement that enables rotary control devices (RCDs) to operate without the aid of an external […]
