Our online seal handbook, which provides guidelines for implementing Kalsi-brand rotary shaft seals in rotating equipment, has been revised. Highlights of the revisions follow. Chapter D7 “Extrusion gap considerations” — […]

We are continuing to explore the installability of Plastic Lined Kalsi Seals™ made with the stiff and highly extrusion resistant -318 seal material combination. Our literature currently reports, “We were […]

Kalsi Engineering has been conducting 10,000 psi tests directed at increasing the pressure capacity of hydraulic swivels, washpipe assemblies, and similar applications. Our previously reported 320-hour and 368 hour tests […]

Plastic Lined Kalsi Seals™ have the most pressure capacity of any polymeric rotary shaft seal. This video explains why.     We are pleased to announce a new video (above) […]

In late 2019 we blogged about concentric and eccentric testing of Kalsi-brand rotary seals with dynamic lips that were significantly wider than those of our 507-series Wide Footprint Seals™. The […]

As a critical provider of products and engineering services to nuclear power plants and the oil and gas industry, Kalsi Engineering has taken various steps to promote safety and preserve […]

Our new generation of high pressure rotary shaft seals is redefining the pressure capacity of high pressure rotating equipment. This video explains how we did it. Here is a new […]

Many rotary seals that partition drilling fluid from lubricant are used with lubricant overpressure, which improves the ability of the seal to exclude abrasives. With partitioning seals, the typically recommended […]

Kalsi Engineering employee Lannie Dietle is the 2020 recipient of Epsilon Pi Tau’s Region 1 Warner Professional Practice Award for exemplary achievement as a practitioner in a technology profession. A […]

In a previous blog, we reported on successful 162°F (72.2°C) tests of the tanged 3.00” (76.2mm) PN 701-10-11 rotary shaft seals with 0.010” (0.25m) intentional runout. In one test, the […]
