Sauer Danfoss 90 Series Pump | 90R055, 90L075, 90R100, 90R130, 90L250 | High Pressure Piston Pump

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

Product Overview: The Sauer-Danfoss (now Danfoss Power Solutions) 90 Series serves as the premier power source for closed-circuit hydrostatic drive systems in mobile machinery worldwide. This selection covers a full displacement spectrum from the compact 42cc (90R042) to the ultra-high capacity 250cc (90L250). Engineered for the most demanding high-pressure environments, the 90 Series integrates charge pumps, relief valves, and diverse control modalities to provide peak performance for rollers, pavers, harvesters, and heavy-duty travel drives. Whether you require 90R (Clockwise) or 90L (Counter-clockwise) configurations, this series delivers industry-leading power density.

Key Technical Advantages:

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

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

• Versatile Control Modalities: Offers Manual Servo (MA), Electric Proportional (EA), Hydraulic Proportional (HA), and more for precise speed and direction modulation.

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

• Robust Through-Drive Capability: Supports powerful through-drive designs, allowing for easy tandem mounting of secondary pumps to enhance system integration.
