Danfoss 42 Series High-Pressure Closed Circuit Variable Piston Pumps

Product Overview: The Danfoss Series 42 is the global standard for high-performance closed-circuit hydraulic drive systems in medium-duty applications. Designed as a balanced axial piston variable displacement pump, this series is engineered to meet the demands of compact mobile machinery and vibration drives. Featured models like the 42R41CANN502ANA2CNA2028NDDNNNNGJ and 42R41DE1A602B3G2CNB2525NNNNNN provide a geometric displacement of 41 cm³/rev. With rated pressure capabilities up to 350 Bar, the 42R41 is the premier choice for road paver travel systems, tandem roller vibration drives, mowers, and compact loaders.

Key Technical Advantages:

• Precision Control Flexibility: Supports diverse control logics including CANN (Hydraulic Proportional) and DE1A (Electrical Displacement Control), ensuring agile response to load changes and superior operational accuracy.

• High Power Density Architecture: Delivers massive torque output within a minimal footprint, ideal for installation in tight engine compartments of compact construction equipment.

• Extreme High-Pressure Durability: Rated for continuous operation at 350 Bar (5100 PSI), specifically optimized to withstand frequent start-stop cycles and heavy-duty shock loads.

• Highly Integrated Design: Features a high-performance integrated charge pump and high-pressure relief valves to keep the main loop primed at high RPMs, preventing cavitation and managing system heat.

• Quiet & Efficient Performance: The optimized 9-piston rotating group minimizes hydraulic ripples and operational noise while maintaining peak volumetric efficiency.
