The 11028920 hydraulic gear pump belongs to the GearMe Pumps series and is produced by Danfoss for fluid power automation. It delivers 6.0 cm³ per revolution, establishing a fixed flow rate for compact machinery. Counterclockwise shaft rotation defines motor orientation and circuit routing. Torque is transferred through a tang drive gear sized 8 × 17.8 mm with a 6.5 mm length, while a rear tang of 8 × 17.46 mm and the same length supports auxiliary coupling. A 52 mm pilot diameter centers the body inside the mounting cavity for precise alignment. Standard catalog port positioning simplifies hose layout in equipment designs. The unit contains no internal valve, so pressure control must be provided by external components.
Installation relies on four through holes that clamp the housing securely to the support surface. An O-ring mounting seal sits between the pump face and the mating pad to block oil escape at the interface. The inlet opening measures 15 × 40 mm with M6 threads to accept the suction connector, and the outlet opening measures 15 × 35 mm with M6 threads for the pressure line. An intermediate flange forms the rear cover, permitting stack mounting with compatible accessories. All dynamic sealing elements are manufactured from NBR to resist common hydraulic oils, and burnished screw finish protects fasteners against corrosion during prolonged service. These features combine to provide a compact, reliable pumping element for automated hydraulic circuits.
