Motor manufacturers routinely answer questions about the differences between submersible and immersible motors and the applications best served by each design.
Paper production requires large amounts of power. The Smurfit Kappa plant in Piteå, Sweden, uses its own biomass boilers to meet part of its energy needs.
In my June column on pump and motor testing, I said that three-phase voltage variation and unbalance can have a significant effect on motor insulation life.
The term “testing” covers a range of processes. Parts supplied for motor manufacturing are tested as they are manufactured and when they arrive at the plant.
Bearing currents occur in specific motor and drive installations and can lead to motor fatigue and failure.

Even though most Winter Olympic venues are held in locations that are likely to have white winters, there is no guarantee that Mother Nature will deliver.

In my July 2014 column, I demonstrated that three-phase voltage variation can significantly affect several alternating current (AC) motor characteristics. If that variation is large, it can also reduce motor life.
When the pump selection process starts, the required flow of the is often the only known variable for an application. For example, a system must move 2,000 gallons per minute (gpm) from a holding tank to another tank or process.
SKF hosted their annual Technical Press Day on June 9, 2014, at Penske Headquarters in Mooresville, North Carolina. This was my first event to cover for Pumps & Systems, so I had a lot to learn! Here are a just a few of the things I picked up at press day.
