Can One Inverter Control Multiple Pumps?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>For standard water treatment and supply systems that use multiple pump motors, stability in pipeline pressure and flow is essential. To meet this requirement, the pump motors need to alternate operation, and a backup pump must be available if any operating pump fails. One solution is to use a PLC to control each pump\u2019s inverter. However, this approach has the drawback of high investment costs, including the PLC controller and numerous inverters.<\/p>\n<p>Understanding these issues, DAT and the international technology group INVT have collaborated to research, develop, and introduce the GD300-16 inverter solution for alternating water pump control and stable pressure. The GD300-16 is a specialized inverter for solutions involving one inverter controlling multiple pumps, also known as multi-pump systems (one inverter controlling two or more pumps). This inverter can control up to 11 pumps.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-12261\" src=\"https:\/\/dattech.com.vn\/wp-content\/uploads\/2021\/10\/1-bien-tan-dieu-khien-nhieu-bom-21910.jpg\" alt=\"1-bien-tan-dieu-khien-nhieu-bom-21910\" width=\"750\" height=\"533\" title=\"\" srcset=\"https:\/\/dattech.com.vn\/wp-content\/uploads\/2021\/10\/1-bien-tan-dieu-khien-nhieu-bom-21910.jpg 750w, https:\/\/dattech.com.vn\/wp-content\/uploads\/2021\/10\/1-bien-tan-dieu-khien-nhieu-bom-21910-300x213.jpg 300w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/p>\n<p><strong>Advantages of Multi-Pump Inverter Control:<\/strong><\/p>\n<ul>\n<li>It meets the requirements for alternating and backup pump control, ensuring stable pressure and flow in pipelines.<\/li>\n<li>The integrated controller within the inverter eliminates the need for a PLC, resulting in a compact and stable control cabinet design.<\/li>\n<li>It incorporates many functions for pump protection and pressure shock prevention to safeguard pipelines.<\/li>\n<li>Lower investment costs are achieved by reducing the number of inverters needed for each pump, as one inverter can control multiple motors without a PLC controller.<\/li>\n<\/ul>\n<h4><span class=\"ez-toc-section\" id=\"5-about-dat\"><\/span>5.
