Series 90 Axial piston pump

Series 90 Axial Piston Pump – High-Performance Variable Displacement Hydraulic Pump

The Series 90 Axial Piston Pump is a family of variable displacement hydraulic pumps designed for closed circuit hydrostatic transmissions. Developed by Danfoss (formerly Sauer-Danfoss), these pumps are widely used in mobile off-highway applications, including construction equipment, agricultural machinery, and industrial vehicles.

Key Features:

1. Closed Circuit Design
   Ideal for closed-loop hydrostatic systems, allowing for efficient fluid circulation between pump and motor.

2. Axial Piston Swashplate Technology
   Utilizes a swashplate mechanism to control variable flow output, offering precise speed and torque control.

3. High Mechanical and Volumetric Efficiency
   Optimized for energy efficiency, reduced fuel consumption, and lower heat generation in hydraulic systems.

4. Wide Displacement Range
   Available in multiple sizes: S90-042, S90-055, S90-075, S90-100, and S90-130, ranging from 10 cc to 130 cc/rev.

5. Multiple Control Options
   Supports manual, electro-hydraulic, pressure compensating, and load sensing controls for flexible system integration.

6. Integrated Charge Pump
   Ensures positive system pressure and supports cooling and filtration functions.

7. High Pressure Capability
   Continuous operating pressure rated up to 420 bar (6,100 psi), depending on model.

8. Compact, Lightweight Design
   Suited for applications with space and weight limitations.

9. Standard Mounting Interfaces
   Compatible with SAE and ISO flanges and shaft configurations for seamless installation.

10. Long Service Life
    Engineered for rugged environments with excellent contamination resistance and shock load durability.
