This design feature provides an opportunity to increase operating efficiency in process plants where pumps are used for a series of repeated but intermittent operations.<\/p>\n<p>The constant presence of fluid in the pump body enables the pump to better handle so-called &#8220;air pockets,&#8221; or accumulations of air bubbles in the pump&#8217;s operating mechanism that can impair its proper operation. In practice, self-priming pumps are previously filled with the relevant fluid through a small port located on the pump body (the chamber where the impeller is located). After this operation, the pump can be operated, triggering turbulence that allows the fluid to rise and &#8220;clear&#8221; the piping of air.<\/p>\n<h2>DEBEM&#8217;s self priming pumps<\/h2>\n<p>One of the most common design methods to induce the priming process involves the following steps:<\/p>\n<ul>\n<li>Creating a reservoir parallel to the utility line, with a volume equal to or greater than the amount of liquid needed to fill the suction line. This tank allows the pump to release air from the pump body and suction line during the priming cycle, replacing it with liquid from the tank that is mixed with the remaining air.<\/li>\n<li>Insert a check valve in front of the pump so that filling operations do not have to be repeated each time the pump needs to be operated.<\/li>\n<\/ul>\n<p>The &#8220;self-priming&#8221; capability of this type of centrifugal pump comes from the ability of the tank to hold the liquid after its initial priming. In describing the concept of self-priming, reference has always been made to the centrifugal pump type. However, there are several types of pumps that can be associated with this term, specifically positive displacement diaphragm pumps, <a href=\"https:\/\/www.debem.com\/en\/products\/mixers-and-peristaltic-pumps\/\">peristaltic pumps<\/a>, and lobe pumps.<\/p>\n<p>Debem offers a range of fully air operated double-diaphragm positive displacement pumps capable of complete self-priming features. In the specific case, the operation of the Cubic and Boxer lines of pumps makes the parallel tank inside the pump body unnecessary. This can be considered a tremendous advantage in applications where limited space conditions require the use of a pump with a smaller size than the standard size that characterizes reservoir models.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" src=\"https:\/\/www.debem.com\/wp-content\/uploads\/2022\/03\/autoadescante.png\" alt=\"\" width=\"1021\" height=\"530\" \/><\/p>\n<h2>Main applications of self-priming pumps<\/h2>\n<p><strong>Self-priming pumps<\/strong> are used in many application areas.
