Oberdorfer™
Oberdorfer™ Pumps has been making world-class quality industrial pumps since 1890. Starting by designing and manufacturing bronze gear pumps, Oberdorfer has since become the leader in pump innovation and extended its product portfolio with centrifugal pumps, flexible impeller pumps, and CHEMSTEEL™ pumps that are available in different materials to match almost any application.
Every pump undergoes rigorous manufacturing processes to ensure that all units meet industrial standards. Constructed and assembled in a state-of-the-art facility, Oberdorfer’s reputation as one of the best makers of industrial pumps cannot be refuted.
PRINCIPLE OF OPERATION
A gear pump develops flow by carrying fluid between the teeth of two meshed gears. One gear is driven by the drive shaft and turns the other. The pumping chambers formed between the gear teeth are enclosed by the pump’s housing and the side plates.
A partial vacuum is created at the inlet as the gear teeth unmesh. Fluid flows in to fill the space and is carried around the outside of the gears. As the teeth mesh again at the outlet, the fluid is forced out. High pressure at the pump’s outlet imposes an unbalanced load on the gears and their bearing support structure.
