The 11029934 gear pump belongs to the GearMe Pumps series and is produced by Danfoss for fixed-flow hydraulic automation. Its displacement of 4.0 cc defines the volume of oil delivered per revolution, allowing flow calculations for system design. The pump turns clockwise, matching prime movers that rotate in that direction. Power is transmitted through a DIN 5482 B17 × 14 L = 10 drive gear so the spline mates with common shafts. Fluid enters through a 1/2 GAS inlet and exits through a 1/2 GAS outlet, which keeps suction and pressure fittings uniform. A rear tang sized 8 × 17.46 × L = 6.5 provides an auxiliary mechanical connection for additional components.
Four mounting holes accept bolts to secure the housing, and a 36.5 mm mounting pilot diameter centers the unit to reduce misalignment. An intermediate flange acts as the rear cover, giving structural support and permitting modular stacking. Standard seals contain hydraulic fluid under pressure, while standard screws allow servicing with common tools. The pump is supplied without a valve setting so external circuitry can handle pressure regulation. Ports follow the standard catalogue layout, enabling direct replacement in existing lines. A standard marking is placed on the top relative to the drive gear for quick identification during maintenance.
