Many users have replaced worn-out motors on older pumps. Close-coupled pump motors made before late 2010 did not have a regulated efficiency.

Q. What primary and secondary containment considerations are recommended for canned motor pumps?

An overlap between 460 and 4,000 volts exists where multiple types of motors and starters are readily available. The question, though, is which one is better?

The objective of this month’s column is to show end users how to hydraulically evaluate their pump systems and determine the power required for the drivers to move the desired flow through the pipi

Worldwide, private and public enterprises are seeking to become more “green” in their operations, either by regulatory mandate or by conscientious choice.

For motors used in the U.S., the selection of an energy-efficient instead of premium-efficient motor is no longer an option. The U.S.

For a large pump package, a medium-voltage motor (above 1,000 volts) incurs significant cost. For this reason, many users ask a common question: How can motor cost be reduced?

This article continues my previous article on power factor (Pumps & Systems, April 2016, read it h

The U.S. Department of Energy (DOE) Advanced Manufacturing Office (AMO) is updating the Motor System Market Assessment (MSMA) that was previously published in 1998.

In certain applications, alternating-current (AC) variable speed drives (VSDs) can offer several advantages over traditional methods of process control, including energy savings, reliability and pr

NASA Tech Briefs describes proportional integral derivative (PID) controllers as "the modern industrial workhorse" because of their distinct role in automating the regulation tasks of toda

Finding ways to effectively reduce equipment, the space it occupies and associated costs is a goal in nearly any industrial application.

What is power factor, and how does it impact your bottom line?

In recent decades, engineers contemplating variable speed pumping for their systems often only consider a variable frequency drive (

A small percentage of bearings achieve their application design life, and in pump and motor applications, bearings are the most susceptible components to premature failure.

At the end of May 2014, the U.S. Department of Energy (DOE) released the Final Rule that amends the regulation for integral horsepower motors.

Energy efficiency has become a major focus for the U.S.

In most U.S. states, running a 100-horsepower pump motor continuously for a year can rack up more than $40,000 in energy expenses.

A new line of explosion-proof, inverter-duty motors provides a solution to the problem of electrical bearing damage caused by energy-saving inverters (also known as variable frequency drives) in pe
