Danfoss Series 45 Open Circuit Axial Piston Variable Pumps

Product Overview: The Danfoss Series 45 is a comprehensive range of high-performance axial piston variable pumps specifically engineered for open-circuit hydraulic systems in agriculture, forestry, construction, and material handling. Known for exceptional reliability and efficiency, this series includes the ERR (Frame J) and ERL (Frame L) specifications. Featured models like the ERR100B, ERR130B, ERL147C, and their Load Sensing variants ERR130BLS and ERL147CLS (e.g., Part No. 11083468) provide precise flow control. Series 45 pumps are designed to maximize machine productivity by minimizing power loss and system heat generation.

Key Technical Advantages:

• Precision Load-Sensing (LS) Technology: Automatically modulates output flow to match actuator demand, eliminating unnecessary relief losses and significantly optimizing fuel efficiency.

• High Power Density Design: Achieves massive displacement outputs (up to 147cc) within a compact cast-iron footprint, ideal for mobile machinery with constrained engine compartments.

• Robust Industrial Construction: Features a single-piece cast-iron housing and reinforced rotating groups, capable of sustained operation under high-pressure conditions for lower total cost of ownership.

• Low Noise & Low Pulsation: Hydrodynamically optimized valve plates effectively suppress hydraulic shocks and mechanical noise, creating a more comfortable operator environment.

• Flexible Configuration Options: Supports various shaft types, mounting flanges, and through-drive capabilities, facilitating the tandem mounting of multiple pumps for complex hydraulic circuits.
