Gear Pump

摘要

A gear pump comprises a casing (1) and gear rotors (2, 3) disposed therein. The gear rotors (2, 3) are lodged in bearing sections (15 to 18) of plain bearings (11 to 14) that are lubricated by the pumping medium. They have at least one cooling duct (39) which is embodied such that cooling varies along the circumference and/or in the longitudinal direction and/or in the radial direction of the plain bearing (11 to 14).
