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 …

Agricultural Irrigation Part 2: Pumping Different Water Sources

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, …

Commercial Agricultural Irrigation Part 1: Selecting the Right Pump

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 Centrifugal Pump Solutions

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 …

Grundfos SMART Dosing Pumps for All Dosing Applications

Many industrial and commercial processes require the use of dosing pumps to transfer fluids with precise accuracy and consistency. Some processes where dosing pumps deliver a consistent, metered amount of fluids or chemicals include water treatment applications such as groundwater, recreational water, and process water for recycling and reuse. Common …
