When rotated, the wings of the impeller are deformed by an eccentric inner contour of the housing and return to their original position, creating chambers that are filled and emptied. On the suction side, the space between the wings becomes larger and the medium is sucked in. On the pressure side, it becomes smaller and pushes the medium out. The pump is therefore inherently self-priming, promotes virtually pulsation-free flow, and treats the medium particularly gently. Because the delivery medium lubricates and cools the impeller, the pump should only run briefly dry.<\/p>\n<p>Compared to rotary or <a href=\"https:\/\/linn-pumpen.de\/en\/gear-pumps\/\">Gear pumps<\/a> Impeller pumps combine several features in one pump. They self-priming, circulate in both directions, are gentle on sensitive products and tolerate small amounts of gas. This makes them well suited for transfer operations, viscous media and for hygienic processes in the food, beverage and cosmetics industries.<\/p>\n<\/div><\/section><\/p><\/div><div
