The three main types of gear pumps are internal gear pumps, external gear pumps and metering pumps. Each of these types has specific properties and areas of application.<\/p>\n<h4>Internal gear pumps<\/h4>\n<p>Internal gear pumps consist of a larger, outer gear wheel and a smaller, inner gear wheel. The inner gear wheel is arranged eccentrically to the outer gear wheel and the tooth spaces of the two gear wheels mesh with each other. This design enables a compact construction and efficient pumping of liquids, especially in applications that require high precision.<\/p>\n<h4>External gear pumps<\/h4>\n<p>External gear pumps consist of two gear wheels of equal size that rotate in a housing. These gears mesh with each other and generate the necessary delivery pressure through their rotary motion. External gear pumps are robust and simple in design, which makes them particularly suitable for industrial applications where large volumes need to be pumped.<\/p>\n<h4>Dosing pumps<\/h4>\n<p>Dosing pumps are special gear pumps that have been developed for the precise dosing of small quantities of liquid. They are often used in the medical and pharmaceutical industries, where exact delivery rates are crucial. Dosing pumps are characterized by their high accuracy and reliability and are often equipped with additional control systems to precisely control the flow rates.<\/p>\n<h4>Comparison<\/h4>\n<p>The different types of gear pumps each have their own advantages and disadvantages. Internal gear pumps offer a compact design and high precision, but are often more expensive to manufacture. External gear pumps are robust and suitable for large flow rates, but can become inefficient at high pressures. Dosing pumps offer maximum precision, but are often only suitable for special applications.<\/p>\n<\/div><\/section><br \/>\n<div  class='hr av-1wot1p-e7f7062be0d20eceb265ee8beaef0459 hr-full  avia-builder-el-4  el_after_av_textblock  avia-builder-el-last  hr-no-shadow'><span class='hr-inner'><span class=\"hr-inner-style\"><\/span><\/span><\/div><\/p><\/div>","protected":false},"excerpt":{"rendered":"<p>Types of gear pumps<\/p>","protected":false},"author":1,"featured_media":0,"parent":1014,"menu_order":0,"comment_status":"open","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-4960","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.3 (Yoast SEO v27.5) -
