The Sauer Danfoss 45 series FRR074 FRR090 FRL074 FRL090 hydraulic pump is a compact axial-piston unit engineered for sustained high-pressure service in mobile and industrial hydraulics. Models FRR074, FRR090, FRL074 and FRL090 offer predictable displacement, low internal leakage and stable volumetric efficiency—qualities needed where uptime and repeatable control matter most.
Built features include reinforced housings, hardened swash plates, high-integrity seals and optional explosion-proof configurations, making the FRR/FRL family resistant to pressure spikes, contamination and extreme temperatures. Each pump is supplied with a one-year warranty and is tested for transient pressure tolerance and long-term thermal stability.

Where they fit
These pumps are commonly applied as main or pilot pumps on machines that demand high flow and durability:
- Agricultural tractors and combines — e.g., John Deere implements: www.deere.com
- Crawler and wheeled excavators — e.g., Caterpillar medium excavators: www.cat.com
- Wheel loaders and material handlers — e.g., Komatsu loaders and Liebherr machines: www.komatsu.com, www.liebherr.com
- Mining and quarry systems — conveyors, crushers and shuttle drives on Sandvik and Volvo platforms: www.rocktechnology.sandvik, www.volvoce.com
Integration tips
Match pump displacement to system flow, verify shaft/mounting orientation (FRR vs FRL), use ISO-rated hydraulic fluid and β10≥75 filtration, and add accumulators or dampeners to smooth transients. Cooling circuits increase continuous-duty life on hot-climate jobs.
FAQ
Q1: What is the difference between FRR and FRL?
A1: FRR vs FRL denotes mounting/shaft and porting configuration; performance envelopes are similar—select per machine layout.
Q2: Are explosion-proof variants available?
A2: Yes—specify explosion-proof options and special coatings for offshore, mining or petrochemical environments.
Q3: Where to get PDFs and technical support?
