Sauer-Danfoss 90 Series High-Pressure Variable Displacement Piston Pumps

Product Overview: The Sauer-Danfoss 90 Series stands as the global premier power source for closed-circuit hydrostatic drive systems in mobile machinery. This selection features core displacements from the compact 55cc (90R055) to the high-capacity 130cc (90R130), engineered to handle the most rigorous high-pressure applications. Featured models include the 90R055MA1AB… (Manual Servo Control) and 90R130EA1B… (Electronic Proportional Control). Renowned for ultimate reliability, exceptional continuous pressure ratings, and an elite power-to-weight ratio, the 90 Series is the premier choice for vibratory rollers, combines, pavers, and heavy-duty material handling equipment.

Key Technical Advantages:

• Extreme High-Pressure Capability: Rated for continuous operation at 420 Bar (6090 PSI) with peak capabilities up to 480 Bar (7000 PSI), ensuring peak performance under heavy duty cycles.

• Versatile Integrated Controls: Offers MA (Manual Servo), EA (Electronic Proportional), and various pressure compensation options for precise flow modulation and directional switching.

• High-Speed Suction Performance: Optimized internal fluid galleries and heavy-duty valve plates support higher continuous RPMs, significantly boosting machine productivity.

• Compact All-in-One Integration: Features highly integrated charge pumps, high-pressure relief valves, and charge relief valves within a single housing, simplifying closed-loop plumbing.

• Rugged Industrial Longevity: Constructed with high-strength cast-iron housings and hardened rotating groups, specifically reinforced for long-term operation in extreme dust and high-vibration field environments.
