The Benefits of Pump Restoration and Coating
Part one of a two part seriesLast April, I received an email from Paul Maier of the Monroe County Water Authority (MCWA) in Rochester, N.Y. Paul attached a copy of his 2009 WEFTEC presentation and...
The Case of Action/Reaction
 Energy efficiency may not always mean total efficiency.The Department of Energy (DOE) has adopted new energy conservation standards for electric motors. The DOE has determined these standards...
Pumps & Systems, June 2007 Named for a technique commonly used on failing pumps, "percussion maintenance" - where a technician beats on the pump's stalled motor with a hammer or rubber mallet...
Advanced motor protective relays provide superior protection for motors and pumps.For years, motor overload relays have been used to protect pumping systems. Traditionally, they monitored current to...
Pumps & Systems, June 2007When a motor fails, users can (1) rewind, possibly for high efficiency; (2) replace the failed motor with a new motor; or (3) invest in a premium efficiency product. Here...
In the past year, the rate of acceleration in the cost of raw materials (including steel, iron ore, copper and aluminum) has reached unprecedented levels in the pump and rotating equipment industries....

Trends in Variable Speed Technology
Choose the right variable speed motor for specific equipment.Why and how do leading OEMs choose a variable speed motor for their equipment? While rated efficiency has been an important driver in the...
It is impossible to balance line-to-line voltages perfectly in a three-phase circuit. In fact, line voltages typically differ by a few volts or more, but a difference that exceeds 1 percent can lead...

Pumps & Systems, June 2007Shaft failures do not happen everyday, but when they do, it can be a challenge to determine the cause of failure. Here's a technical explanation of what happens when the...
Production, distribution and refining applications in the oil and gas industry rely heavily on motor-driven pumps and pumping systems. Keeping electric motors driving critical operations at peak...
Optimized Energy-To-Thrust Ratio and Mechanical Reliability: The Keys to Submersible Mixer Cost Efficiency
Energy is the largest ongoing cost of mixer operation, so it is vital to carefully consider the energy-to-thrust ratio (sometimes called the “water-to-wire” ratio) for each and every mixer...
