Rotoʼs external gear pump with its innovative design is compact, efficient and ensures longer service life. These gear pumps are having simple four piece construction, specially designed to handle thinner to thicker & even corrosive liquids with lesser or no lubrication. Rotoʼs external gear pumps are available in various materials and can also be customized for high pressure applications.
Gear pumps are one of the most common types of positive displacement pump. These pumps operate by an unchanging volume of fluid passing between the teeth of two meshing gears and their casing at a constant rate. As the gears rotate and the meshed teeth separate, a partial vacuum is formed that fills with fluid. As the gears continue to rotate, they trap the liquid and move it around the casing from the suction to the discharge point.
