Bearings are a vital component in the wastewater industry. Breakthroughs in bearing technologies help wastewater companies extend the life and operational efficiency of critical applications—even when those applications are operating in harsh conditions, with corrosive fluids and under heavy loads.

The Himalayan Mountains tower over some of the most rugged terrain and harshest climate conditions on the planet. Melting snows from Mount Everest, K2 and hundreds of other snow-capped peaks carve out more than 6,000 rivers in Nepal, China, Bhutan, India and Pakistan.
Minimizing pump downtime directly affects the bottom line. Sealless mag-drive and canned-motor pumps, commonplace in the petrochemical and power industries, enhance reliability and reduce emissions and leakage compared with more traditional sealed pumps. The choice between sealless and sealed pumps often involves savings in both time and money.
For any bearing used in rotating machinery, applying best maintenance practices and using the correct enabling tools can help contribute to maximum bearing service life. These practices include proper storage and mounting, adequate lubrication, and close monitoring and inspection that can uncover the root causes of any damage.
Many industries use variable frequency drives (VFDs) with induction motors. Introduced in the 1960s, VFD technology has advanced considerably during the past 50 years.
Despite their simplicity, centrifugal pumps often experience repeat failures that even seasoned maintenance and reliability professionals have trouble preventing.
Minimizing pump downtime directly affects the bottom line. Sealless mag-drive and canned-motor pumps, commonplace in the petrochemical and power industries, enhance reliability and reduce emissions and leakage compared with more traditional “sealed” pumps. The choice between sealless and sealed pumps often involves savings in both time and money.
A multistage BB5 diffuser machine in oil transfer service in the Middle East had been in operation for many years without problems. After a routine maintenance strip down and rebuild, the pump experienced a high thrust bearing temperature of 105 C, which caused it to alarm and shut down. The temperature range had previously been 75 C to 85 C.
Within the oil and gas industry, the rotating shafts of equipment—such as pumps, motors, compressors, gearboxes and turbines—perform an essential function in both upstream and downstream applications. This rotating equipment ensures process flow and the safety of employees and the surrounding community.
Few industries can tolerate the unscheduled downtime of critical equipment. In refinery operations, it can have particularly serious implications. For an operation that runs 24 hours per day year-round, the losses—in both production and profitability—can be staggering.
