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 …
Pump efficiency can hugely impact overall lifecycle costs. A Grundfos pump energy audit helps companies to determine potential savings and provides suggestions to improve performance and efficiency. Switching to energy-efficient pumps helps companies to reduce CO2 emissions as well as energy expenses, often with a quick return on investment. Benefits …
Irrigation solutions for agricultural farmers rely on a variety of factors forcing growers to have in-depth knowledge in many areas, including soil properties, climatology, botany, and the quality and quantity of water sources. An understanding of engineering and hydraulics is also necessary to choose the right type of pump system, …
There are several different types of irrigation, with some definitions being quite broad and others very specific such as agricultural irrigation. Irrigation enhances both the quality and quantity of agricultural crops and has been practiced for thousands of years. With the right combination of soil, sun, temperature, and water, plant …
End suction pumps are one of the most common classes of centrifugal pumps, with a simple design providing tried-and-true reliable pumping solutions for centuries. The most common type of end suction pump is single stage and operates on the basic principle of fluid flowing into the inlet of the pump …
