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.
