Motors

Proper alignment of the pump shaft with the driver can reduce vibration and significantly improve reliability.
Unanticipated noise and vibration can be problematic for both occupants and processes within structures.
Last September, we spoke about the importance of pipe-to-piping alignment, evaluating actual numbers, and tabulating stress values as they approach yield stress of pipe at various values of misalignment. This time, we will discuss the effects of pump-to-motor misalignment, beyond hype or generalities, by numerically quantifying the conclusions.
Owing partly to tradition, the shafts of electric motors are often larger than those of the equipment they drive.
Bigger is better — or at least it used to be
Understanding resonance is essential for solving problems of increased vibration.
How do I move from my situation to a better one? In other words, is it possible to retrofit a less-than-optimal installation with a better solution, and how?
New motor starting controller provides one solution.
A paper or an electronic work order system can be used to capture alignment data.
Couplings are often forgotten until a project is nearing its end.

Water and wastewater systems in the United States use a tremendous amount of power. The EPA estimates that these systems use 50 trillion watt-hours annually at a cost of $4 billion. Combined with electric rate increases upward of 20 percent in a single year, water and wastewater system operators are left with an enormous strain on their budget.

Data-driven visibility helps protect industrial processes and motors.
In the food industry, stainless steel performs more productively and efficiently.
Energy efficiency may not always mean total efficiency.
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 - often indicates motor deficiencies in his diaphragm pump.
Advanced motor protective relays provide superior protection for motors and pumps. pump system optimization
When 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.
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.
