1,Product Overview

Sauer-Danfoss JRR hydraulic pump belongs to the proven Series 45 open-circuit axial-piston family. It packages swash-plate technology into an ultra-compact body that delivers up to 310 bar continuous (400 bar peak) pressure while maintaining high volumetric and mechanical efficiency. With displacements ranging from 25 cm³ to 75 cm³/rev, the JRR frame covers the most common medium-duty power bands requested by mobile-equipment builders. A through-drive housing, multiple control options (pressure-compensated, load-sense, electric proportional, electro-displacement, three-position), and SAE/ISO mounting interfaces let one pump core serve dozens of machine architectures—from skid-steer loaders and telehandlers to drilling rigs and municipal trucks—without re-engineering surrounding components.

2, Key Advantages

•  High Power Density – Up to 92 % overall efficiency lowers fuel burn and heats less.
•  Built-in Contamination Resistance – Steel-backed, PTFE-coated slippers and bronze-plated cylinder block extend life in 22/19/16 ISO oil.
•  Service-Friendly – Cartridge-style control valve and external swash-plate angle indicator enable 15-minute on-site calibration.
•  Modular Through-Drive – Accepts 100 % tandem pumps or fixed gear pump piggy-back for auxiliary functions, saving engine PTO ports.
•  Global Parts & Support – Same cartridge kits fit JRR, KRR and LRR frames, reducing aftermarket inventory.

3,Typical Applications

•  Skid-steer & compact track loaders
•  Telescopic handlers & aerial lifts
•  Mini excavators < 8 t
•  Road sweepers & salt spreaders
•  Drilling & foundation rigs
•  Forestry mulchers & harvesters
