Today’s process industries utilize powders for a variety of purposes. While many processes use similar activities to turn raw materials into finished products, the complexity of handling and transferring powders has earned this material category a particular reputation among process engineers and others involved in the design and operation of …
Power sensors on pumping equipment are a key tool to provide valuable predictive maintenance that protects equipment and delivers cost savings. Monitoring a pump’s power supply provides insight into any changes in the workload of the pump. Fluctuations in power can be set to trigger the equipment to shut down …

The Grundfos MP 204 provides state-of-the-art electronic motor protection for asynchronous motors and can be installed on both single and three-phase motors. The MP 204 unit includes a control …
Our previous posts have discussed what dry running is in the damage that it can cause up to and including complete pump failure. Very costly repairs or total pump replacement may be required if your pump is left dry running even for under a full minute. A possible dry-running situation …
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 …
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 …
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 …
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 …
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 …
Pump cavitation is a serious issue that has a destructive impact on many aspects of a pump, but most likely will destroy the impeller, which leads to poor pumping operation and significantly reduces the lifespan of the pump. Cavitation causes serious damage and erosion to impellers, causing even new impellers …
