Pump Failure Due To Dry Running

Dry running is a common and potentially expensive issue that many pump operators can experience in a variety of applications. In any process where variable or constant torque pumps are distributing liquid, such as in water treatment or distribution, chemical processing, grinding, mixing, or other liquid distribution applications it is …

What is Pump Dry-Running?

Dry running is exactly what it sounds like, running a pump dry without enough or any liquid. When a pump is dry running, it is pushing only air around instead of circulating fluid, which leads to potentially expensive damage and worsens pump longevity. Pumps should never be operated running dry …

Predictive Maintenance for Pump Systems

Pump managers interested in protecting their investment realize the benefits that power sensing provides to cost-efficient pumping system management. Power sensing provides quick, maintenance-free, and economic feedback on pump equipment status and operations. Pump Monitoring: Proactive, Predictive Maintenance Well-maintained and managed pumps contribute to an efficient manufacturing operation with a …

What Are Sine Wave Filters?

In our last blog, we discussed AC power, frequency, and sine waves. Sine wave filters are critical when running VFD pumps and provide valuable benefits such as eliminating heating, audible noise, and problems with motor/cable insulation failures. Sine Wave Filters and dV/dt Sine wave filters also eliminate high dV/dt, the …

What are Sine Waves?

When dealing with supply power and motors, frequency is a predetermined factor. A basic understanding of frequency properties helps engineers and operators to understand motor frequency issues, variable frequency drives (VFDs), as well as voltage and power phase. AC Power and Frequency In electric circuits, the time rate of energy …
