The 11002066 pump belongs to the H1P Axial Piston Single Pumps series from Danfoss and supplies variable hydraulic flow to mobile machinery where electronic control and compact mounting are required. It delivers a maximum displacement of 78 cc per revolution so the system can match flow to load demand. Electrical displacement control varies the swashplate angle without mechanical linkages, and a 24 V input powers this circuit. A sealed Deutsch DT04-2P connector carries the control wiring and resists moisture and vibration. Counterclockwise rotation aligns the pump with engines that turn in the same direction, preventing cross-shaft stresses. A 14-tooth, 12/24 spline input shaft transfers torque from the prime mover while maintaining positive engagement under high load. The SAE C 4-bolt mounting flange secures the housing to standard bell housings, and the twin-port endcap that uses a Code 62 metric 4-bolt flange simplifies routing of high-pressure and case-drain lines.
An internal charge pump displaces 17 cc per revolution to replenish the closed loop, and a charge relief valve set at 24 bar protects low-pressure components from overload. The main circuit high-pressure setting is 420 bar, providing the margin needed for demanding propel functions while staying within fatigue limits. Suction filtration on the inlet side removes particulate contamination and extends bearing life. A calibrated 1.3 mm orifice labeled A+b meters cooling flow through the rotating group to stabilize temperature during continuous operation. Main ports follow the ANSI O-ring boss pattern for reliable sealing under cyclical pressure. There is no auxiliary pad, so the pump occupies less axial space in confined engine compartments, and displacement limiters are omitted, allowing the electronic controller to use the full stroke range when maximum vehicle acceleration is required.
