Sauer Danfoss 90 Series Pump | T90R100, 90R100 | Manual Servo Control (MA) | Closed Circuit Piston Pump

Sauer-Danfoss 90 Series T90R100 High-Pressure Closed-Circuit Piston Pumps

Product Overview: The Sauer-Danfoss 90 series (encompassing T90R, T90L, and T90M) stands as the industry standard for hydrostatic drives in mobile machinery worldwide. As a core 100cc model, the T90R100 is engineered specifically for high-pressure closed-circuit systems, integrating charge pumps, high-pressure relief valves, and essential control valve groups. Featured models like the T90R100MADNN… utilize the classic MA (Manual Servo Control), allowing operators to precisely modulate the swashplate angle via mechanical input for smooth, stepless control of machine speed and direction. Its rugged build and superior power density make it the premier choice for asphalt pavers, rotary drilling rigs, and combine harvester drive systems.

Key Technical Advantages:

• Extreme Pressure Durability: Rated for continuous operation at 420 Bar (6090 PSI) with peak capabilities up to 480 Bar (6960 PSI), ensuring consistent power under heavy loads or uneven terrain.

• Responsive Servo Control (MA): Equipped with a manual servo regulator that provides excellent tactile feedback and precision, ensuring machine agility in demanding work environments.

• Highly Integrated Architecture: The pump housing consolidates multi-function valves (circuit protection), charge relief valves, and a charge pump, drastically simplifying external plumbing and saving space.

• Full Lifecycle Reliability: Constructed with high-strength cast-iron and specialized hardened piston groups for ultimate resistance to vibration and fatigue, significantly reducing maintenance intervals.

• Wide Displacement Compatibility: The 90 series offers versatile frame sizes including 042, 055, 075, 100, 130, 180, and 250cc, providing unmatched system flexibility.
