Product Description

Sauer Series 20 Hydraulic Pumps & Motors for Road Rollers

Product Overview: The Sauer-Danfoss Series 20 is a legendary benchmark in hydrostatic transmissions, specifically engineered for heavy-duty machinery such as road rollers, excavators, and pavers. This featured selection includes core high-performance models: PV21 and PV22 Variable Displacement Pumps, paired with MF21 and MF22 Fixed Displacement Motors, specifically tailored for equipment like the CA25 and CA30 road rollers. Utilizing a classic axial piston swashplate design, these units allow for infinite displacement adjustment by varying the swashplate angle, delivering precise and powerful drive for the harshest environments.

Key Technical Advantages:

  • Classic Swashplate Design: Simple yet extremely robust construction capable of withstanding frequent reversals and high-frequency shock loads, drastically reducing maintenance needs.

  • High Power Density: The compact housing integrates the charge pump and control valve manifolds, optimizing the chassis layout for road rollers and compact machinery.

  • Excellent Self-Priming Capability: Optimized for both open and closed circuits, ensuring the motor delivers smooth, high-torque output even at ultra-low speeds.

  • Superior Compatibility: Widely utilized in world-renowned road rollers (e.g., Dynapac CA25/CA30 series), ensuring seamless interchangeability with original equipment parts.

  • Target Applications: Vibratory roller travel drives, excavator hydraulic systems, asphalt pavers, and material handling equipment.

Detailed Models & Parameters:

  • Core Series: Sauer-Danfoss Series 20 (Axial Piston Units).

  • Model Keywords: PV21, PV22, MF21, MF22, CA25, CA30.

  • Technical Specs Decoding:

    • PV21/PV22: Variable displacement axial piston pumps with support for manual or hydraulic proportional control.

    • MF21/MF22: Fixed displacement axial piston motors for constant high-torque output.

  • Pressure Specs: Continuous operating pressure up to 21 MPa (210 Bar), with resilience against peak load cycles.

  • Rated Speed: Engineered to meet the full RPM spectrum from crawling operations to high-speed transit.
