1,Product Overview

The Sauer Danfoss 42R28 is a high-performance variable displacement axial piston pump under the 42 Series hydrostatic product line. Adopting a classic swash plate design, it is tailored for medium-power hydraulic systems, with a displacement of 28 cm³ (1.71 in³) and a maximum operating pressure of 345-350 bar (5000 psi). It is widely recognized for its stable performance and strong adaptability in mobile machinery applications.

2,Core Technologies & Advantages

. Flexible Control Modes: Supports multiple control options, including mechanical/electric feedback control, hydraulic/electric proportional control, and three-position electric control, ensuring low hysteresis and rapid response to system commands.

. Efficient Speed Regulation: The cradle-type swash plate with a hydraulic servo cylinder enables infinite variable speed adjustment (0 to maximum) and bidirectional operation (forward/reverse) by changing the swash plate angle.

. Compact & High-Density Design: Features small size and high power density, allowing easy integration into space-constrained hydraulic systems while delivering strong power output.

. Quiet & Reliable Operation: Optimized internal structure reduces operating noise; mature manufacturing processes ensure long-term stable performance even in harsh working conditions.

3,Application Scope

The Sauer Danfoss 42R28 is mainly applied in mobile construction machinery and industrial equipment that requires medium-power hydraulic drive. Typical application scenarios include:

• Road construction: Road rollers, asphalt pavers

• Earthmoving machinery: Small to medium excavators

• Special engineering: Horizontal directional drills

• Marine equipment: Ship cranes
