11033087

The 11033087 gear pump is part of the GearMe Pumps series manufactured by Danfoss. Intended for hydraulic automation, the unit converts mechanical input into a steady oil flow for actuators and steering circuits. It delivers a fixed displacement of 17 cc per revolution, giving consistent volumetric output whenever the drive turns. The pump is configured for counter-clockwise rotation when viewed from the shaft end, so direction must match the prime mover. A 1:5 tapered drive shaft transmits torque efficiently, and an M12 × 1.25 thread at the tip accepts standard locking hardware. The 50 mm pilot diameter centers the body in mating brackets to limit vibration and misalignment. Static seals are formed from Viton to withstand elevated oil temperatures and aggressive additives. The unit is supplied without a valve setting, leaving pressure regulation to external components and supporting predictable circuit behavior.

Installation is simplified by two mounting holes that pass through the housing; these through-body bolts draw the pump securely against the engine or adapter plate and eliminate separate clamps. The rectangular inlet port measures 20 × 40 mm and is tapped for M6 screws, offering ample cross-section for low-restriction suction flow. Discharge leaves through a 15 × 35 mm outlet, also prepared for M6 fasteners to keep hardware uniform across connections. A BABSL lip seal is fitted around the shaft to contain pressure oil while accommodating minor axial movement generated during load changes. The compact port pattern keeps hoses close to the casing, supporting tight packaging in mobile machines where space is limited. Together, the through-body mounting and matched inlet and outlet sizes reduce installation time and help maintain stable hydraulic performance over extended service intervals.
