"Once installed end-users obtain the latest in motor grounding seal technology, which helps boost equipment reliability, meet regulatory demands and reduce maintenance costs."

Introducing the new Inpro/Seal Current Diverter Ring (CDR™, patent pending).

Inpro/Seal Company has long been associated with the electric motor industry as the sole supplier to OEMs for their IEEE-841 Premium Efficient motors for industrial use.

Now, with the newly-developed CDR technology, Inpro/Seal is the logical supplier of bearing protection devices for motors using Variable Frequency Drives (VFDs) to adjust the speed output of Alternating Current (AC) motors. The motor manufacturers can conveniently package the motor, drive and CDR.

Only 40% of the motors in industrial use today employ VFDs for powering motors. According to industry sources, this percentage will increase significantly, near term. VFD-controlled motors inherently produce destructive shaft currents that must be redirected around the bearings; otherwise, unmitigated electrical currents initiated by the VFD and induced by the motor shaft destroy the bearings. The Inpro/Seal CDR safely diverts these currents and saves the motor bearings.

When operating centrifugal equipment such as pumps and fans, a 10% reduction in speed will result in a 27% reduction in energy consumption of the pump or fan. Rather than being limited to fixed system parameters such as rigid pump performance characteristics and pressure reduction valves in the system, centrifugal equipment can be programmed to respond to system requirements.

Inpro's CDR components are developed, engineered, tested and manufactured completely within the Inpro/Seal Company facilities in Rock Island. They are made from corrosion resistant bronze in any shape or configuration needed by the customer.

The new device will be available from all major motor manufacturers around the world as well as EASA repair facilities. It will be available as a "press-in," a "Clip-on," a "split" configuration or an "MGS" design Inpro/Seal, which prevents contamination from entering the motor bearing enclosure while diverting destructive shaft currents.

Inpro's reputation for customer service and customer accommodation is well-known and appreciated by clients in the process industries who have worked with Inpro/Seal Company to solve bearing-related problems. Same-day shipments and point-of-use technical service are available 24/7 which is characteristic of Inpro, where innovation is a way of life.

Inpro/Seal Company is the originator and the world's number one manufacturer of bearing isolators, used to protect motor and pump bearings, machine tool spindles, turbines, fans, gear boxes, paper machine rolls and many other types of rotating equipment. Additional applications include the sealing, handling, processing, packing and storage of dry particulates, powders and bulk solids.

Of the 4,000,000+ bearing isolators delivered, almost all of them continue to be in operation in process plants worldwide, where end users continue to report significantly reduced operating costs with increased productivity and reliability. Protected bearings have run 150,000 hours (17 years) or more, eliminating the need for costly maintenance and repair. Documented cases show that a plant can more than double the mean-time-between failure (MTBF) and reduce maintenance costs by at least half, with users reporting an extremely high ROI.

Using A Water Barrier, The Inpro/Seal Water Mizer Shaft Seal Provides Sealing Efficiencies Other Methods Cannot Attain. No Moving Parts, No Friction, No Wear, No Contact, No Energy Consumption.The Inpro/Seal Current Diverter RingA bearing protection device, the Current Diverter Ring prevents contamination from entering the motor bearing enclosure of VFD controlled motors and impedes stray shaft currents from traveling to coupled equipment such as rotary feed valves, mixers, blenders, agitators, pumps, fans and related centrifugal equipment.The Return On Investment Calculation Worksheet, an Excel spreadsheet module, allows users of pumps and motors to quantify the effectiveness of bearing isolators when applied to rotating equipment. Available only from Inpro/Seal, once completed, it allows plants to calculate their own ROI (return on investment) relative to the use of bearing isolators, including benchmarks of current repair costs and the effect of doubling the reliability of their rotating equipment.The Inpro/Seal manufacturing complex is the largest of its kind in the world devoted to the engineering, research, improvement, testing and manufacture of bearing isolators.Green Is The ColorExcel module answers the long standing question of how long a rolling element bearing will last. By plugging in certain data, this interactive Excel module shows an end user how long they can expect their roller element ball bearings to last.The OM32 Series was developed exclusively for Oil Mist applications to contain stray mist and keeping it from entering the environment. Once installed end users receive levels of protection previously unattainable. With the oil mist bearing isolator, the lubricant is coalesced to a liquid and drains back into a system sump or reservoir instead of into the environment. Bearings are protected, shafts are sealed and environmental housekeeping problems are solved.The Mine Safety and Health Administration (MSHA) has recognized Inpro/Seal%u2019s Belt Conveyor Idler/Roller Bearing Isolator, assigned it tag #AP2007-93304 and posted it on their website%u2013 www.msha.gov. Once installed it will protect idler bearings in mining operations and provide additional safety and reliability.While they are engaged with a rotating shaft and effectively sealing, contact seals, including lip seals and face seals, consume significant energy. According to industry sources, that rate of power consumption is, on average, 147 watts per seal.Inpro/Seal, the manufacturer of bearing isolators, has significantly revised - www.inpro-seal.com - their long standing website.

It is a valuable source of information and useful tool to anyone involved in the management, maintenance, repair and operations (MRO) of motors, machine tool spindles, turbines, fans, gear boxes, paper machine rolls, pumps and other types of rotating equipment used in industrial/process plants. It includes important and useful information on the evolution of the bearing isolator, including: how and why it was invented; how it works; how and why contact seals fail in a short period of time; how to eliminate catastrophic failure; how to reduce power consumption in rotating equipment; costs; maintenance; configurations and much more.The Inpro/Seal bearing isolator is a permanent replacement for contact seals that wear out in a matter of months.The bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized so that they don%u2019t separate from one another while in use. Typically, the rotor turns with the rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of the bearing enclosure and the lubricant in. While a lip seal or contact seal operates with contact, the bearing isolator makes no contact, never wears out and can be used over and over for many years. Contact seals, on the other hand, have a 100% failure rate.The Air Mizer%u2122-PS was developed to seal shafts where dry particulates, powders and bulk solids are handled, processed, packaged and stored.
