Product Description
Sauer-Danfoss 90 Series Hydraulic Pump & Motor for Concrete Mixers
Product Overview: The Sauer-Danfoss 90 series is a line of high-pressure axial piston variable displacement pumps designed specifically for closed-circuit systems. It is the global benchmark for drive systems in concrete mixer trucks, tank trucks, and heavy-duty construction machinery. Renowned for its exceptional reliability and power density, the 90 series ensures smooth and continuous drum rotation under varying loads. Core models such as the 90R075 and 90L042 integrate advanced charge pumps and control valve groups, serving as critical components for job-site productivity.
Key Technical Advantages:
Heavy-Duty Closed-Loop Design: Optimized for bi-directional flow and high-pressure environments. Models like the 90R075M81BC60P3C7D03GBA424224 feature high rated pressures, easily handling start-up shocks and frequent reversals during mixing cycles.
Compact & Highly Integrated: The 90 series integrates a charge pump and high-pressure relief valves within the pump housing, simplifying hydraulic plumbing on mixer truck chassis and reducing potential leakage points.
Precise Displacement Control: Models like the 90L042KA1NN80D3C3L03NNN424224 offer millisecond-fast variable response, allowing operators to precisely control drum RPMs and prevent concrete segregation.
Extended Service Life: Engineered for the dusty and humid environments of batching plants. The 90 series utilizes reinforced bearing supports and high-performance seals, significantly reducing downtime and maintenance intervals.
Specific Models & Technical Parameters: This product line features core configurations: 90R075M81BC60P3C7D03GBA424224, 90L042KA1NN80D3C3L03NNN424224, and the full 90R, 90L, 90M range.
Displacement Range: Covers mainstream sizes from 42cc up to 130cc.
Max Pressure: Rated at 420 Bar (42 MPa); Peak cycles up to 480 Bar.
Rotation Options: Available in Clockwise (R) and Counter-Clockwise (L) configurations.
Applications: Concrete mixer trucks, pavers, road rollers, and off-highway vehicles.
