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 […]
A new video about high-pressure oil seal testing
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 […]
Testing Super Wide Seals™ for drilling fluid-to-oil partitioning service
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 […]
400 psi reverse pressure testing with runout
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 […]
A 100-rpm test of a 10.49-inch RCD seal at 1,500 psi
We are pleased to announce a successful 200-hour-plus test of a 10.49-inch (266.45mm) BDRP Seal™ at 100 rpm and 1,500 psi differential pressure. The used test seal is still in […]
Two 1,500-psi tests of 10.49-inch BDRP Seals™ at 75 rpm
BDRP Seals (Figure 1) are Plastic Lined rotary seals that were developed to provide hydrodynamic interfacial lubrication in either direction of differential pressure and either direction of rotation. This design […]
15 & 100 psi reverse pressure testing with drilling fluid and runout
In June of 2019 we reported on the successful testing of 3.00” (76.2mm) PN 701-10-11 rotary shaft seals in “reverse pressure” conditions where the pressure of the drilling fluid was […]
368-hour, 10,000 psi test of a washpipe assembly
On July 26, 2018 Kalsi Engineering announced a collaborative effort with Packard International, Inc. to provide high pressure washpipe assemblies to the oilfield drilling industry. On May 6, 2019 we announced the […]
