Variable frequency drives (VFDs) adjust the pressure or flow on pumps to meet the actual demand. VFDs control the frequency of electricity delivered to pumps and fans. VFDs can provide significant power savings by controlling the rotational speed and frequency of electrical power supplied to the pump motor. VFDs are …
Diaphragm metering pumps provide precision and accurate dosing to many applications that require consistent flow. While precision and accuracy are very similar definitions referring to the quality of a measurement, they provide different indications. Precision refers to the degree to which a process or instrument will repeat the same value, …
Industrial wastewater treatment management programs are required to meet national guidelines established by the Environmental Protection Agency, EPA, regarding the discharge of industrial wastewater and the level of contaminants allowed. The EPA established Effluent Limitation Guidelines (ELGs) as part of the Clean Water Act of 1972 which limits the maximum …
Sealless, magnetic drive pumps offer many benefits over sealed, traditional pumps even those with costly and complex seal support systems. These traditional, sealed pumps can often experience leaks which can be a serious safety concern in many applications as well as causing costly repairs and cleanup efforts. In many applications, …
The design of a pump system significantly impacts the overall value that it provides in many different areas such as configurations and features as well as material and operating parameters and expenses. Design to Value is a term that describes a multidimensional, fact-based approach that allows companies to improve margins …
It is important to partner with the right service provider for process pumps and equipment operations and maintenance. Choosing the right process equipment service provider can be challenging and there are many factors to consider to mitigate risk and improve reliability in your plant. The right service provider will provide …
A metering pump is a type of pump that is used to precisely transfer a volume of liquid with accurate control of the flow rate over a specified period of time. Metering pumps are sometimes also used for dosing or injecting various liquids and are used in different industries. Metering …
Precise and accurate control of dosing flavorings, essence, fragrances, or any other food additive is key to high product quality. Any slight alteration of a flavorant can significantly alter the characteristics of a food or beverage product causing it to become too sour, sweet, or tangy. Different additives can change …
One of the most important aspects in commercial cultivation is the need for farmers to get nutrients to their crops. A nutrient dosing or delivery system that injects fertilizers or other water-soluble solutions into large batch tanks or irrigation lines is known as fertigation. Some automated systems manage only the …
Water cooling towers are used in various industrial processes to cool process equipment such as machinery and presses, chillers, and air-conditioners to prevent overheating and maintain an ambient air temperature. Water leaves the cooling tower in a few different ways, mostly through evaporation. A small amount of water may leave …
