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.

High-speed rotary seal testing in support of dredging and submersible pump applications
Submitted by
on
Kalsi Engineering recently completed an 1,800 RPM rotary seal test on a 2.75” shaft. This testing builds on previous successful testing performed at dredge and submersible pump operating conditions. The previous tests were reported on in December of 2021 and April of 2022. For the new test, we used a rotary seal material that…

High-speed rotary seal testing of Kalsi Seals at 1,800 RPM
Submitted by
on
In December we reported on successful high-speed rotary seal testing (1,290 RPM) with two Kalsi Seal geometries at dredging and submersible pump conditions. We recently completed even higher speed rotary seal testing with these seals. As previously described, the high-speed rotary seals used in this testing have a significantly lower hydrodynamic pumping related seal…

Rotary seal testing of Kalsi Tanged Seals at 500 psi differential pressure
Submitted by
on
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 where the environment fluid pressure is greater than the seal lubricant pressure, a condition we refer to as reverse pressure. In June 2019 we reported…

High Speed Testing of Kalsi Seals
Submitted by
on
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 an abrasive fluid environment, and they have a significantly lower hydrodynamic pumping related seal leak rate than other Kalsi Seals used in high-speed applications. This…

Sealing Advancements for Rotating Control Devices (OTC-31159-MS)
Submitted by
on
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. Dietle, and their team have been developing seal technology targeted at increasing the pressure and speed capacity of self-contained Rotating Control Devices. Through extensive analysis,…

Kalsi Tanged Seals tested at 300°F
Submitted by
on
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 condition as “reverse pressure”. Many un-tanged seals slip circumferentially in the seal groove in reverse pressure operation. The seal tangs and mating pins in the…
