It was the start of an ongoing journey to supply permanent bearing protection to industrial rotating equipment. The first Bearing Isolator was installed in 1975 at the Grain Processing Corporation plant in Muscatine, Iowa, to address a critical issue. It would perform much better than any other labyrinth seals made by pump manufacturers because it would hold off any contamination without contact.” “We finally found a combination of rotor and stator that would keep oil in, but also ward off contamination up to and including a fire hose. “It took about six months to design something that would work in severe hose-down conditions,” said Orlowski.

As he experimented with labyrinth seals, Orlowski started with the challenging application of pumps in the corn processing industry, which were cleaned daily – with a fire hose. Orlowski then turned his attention to solving this issue on process pumps, where rubber lip seals were standard. Orlowski and his team retrofitted the API refinery pumps with standard API labyrinth seals, made with a rotor and a stator. It went through there and into the bearing housing, causing bearing failure and a catastrophic wreck.” One of the single spring mechanical seals started to spray water and of course the water was coming out of the seal and going right through and under the lip seal, which was worn. The building structure began to suffer and several windows had fallen from the 110-story building onto the street below.Īccording to Orlowski, “They were refinery pumps with rubber lip seals, which is a rarity. One of the chilled water pumps had failed, though, resulting in a cooling system failure. Orlowski was working in the pump distribution and repair business when he was called out to repair and retrofit 16 HVAC pumps at Chicago’s Sears Tower.Įven though it was February in Chicago, the south side of the building was supposed to be cooled because of the intense daytime sun load.

The awards, 10 of which were presented in 2017, celebrate major innovations as well as incremental improvements that increase efficiency, productivity and ultimately, the bottom line.Falling Windows: The Origin of the Bearing Isolator We are a proud distributor of Inpro/Seals company’s products, which is world leading manufacturer of engineered bearing isolators and seals for rotating equipment in various industry’s. The Processing Breakthrough Products Awards recognize manufacturers that develop novel solutions to help manage and navigate tough processing environments and meet changing standards for modern processing facilities. The VB45-S Bearing Isolator, as with all Inpro/Seal Bearing Isolators, can be shipped the same day orders are placed, ensuring our customers get their equipment operating as quickly as possible. ![]() A short overall length allows for easy installation, often without the need for equipment modifications. (15.88 mm), the VB45-S Bearing Isolator is the most compact IP66 rated Bearing Isolator available. With an overall (axial) length of only 0.625 in. For superior protection against lubrication loss, the VB45-S utilizes either an enlarged D-Groove to capture oil and return it to the bearing housing or a grease band to block grease from traveling down the shaft and escaping from the bearing housing. The VB45-S Bearing Isolator utilizes Inpro/Seal’s patented XX Interface coupled with an enlarged contamination chamber to achieve an IP66 rating, the standard for premium ingress protection against both harmful particulates and liquids, making it one of the best performing Bearing Isolators available. ![]() Like all Inpro/Seal Bearing Isolators, the VB45-S design protects against contamination ingress and lubrication loss.
