Product Description
Danfoss 45 Series ERL & ERR High-Efficiency Axial Piston Variable Pump
Product Overview: The Danfoss 45 series (covering ERL and ERR configurations) is a range of industrial-grade variable pumps engineered for open-circuit mobile hydraulic systems. This series excels in high-displacement segments (100cc and 130cc), delivering robust power output at a rated pressure of 310 Bar. Featuring advanced LS (Load Sensing) control technology, the 45 series pumps sense load demand in real-time and modulate flow precisely, significantly reducing system heat and engine fuel consumption. Whether the ERL100B or ERR130, these pumps set the industry standard for power-to-weight ratio and long-term durability.
Key Technical Advantages:
Intelligent Load Sensing (LS) Control: Models like the ERL100BLS feature high-sensitivity load-sensing compensators, ensuring pump flow output is perfectly synchronized with actuator demand to maximize overall system efficiency.
Heavy-Duty Mobile Application Design: Specifically built for harsh off-road environments. Rated for an operating pressure of 310 Bar (4500 PSI) with peak cycles up to 400 Bar, ensuring structural stability under frequent reversal and high-frequency shock loads.
Robust Thru-Drive Capability (A1N): Features superior thru-drive interfaces (e.g., codes A1N or 3S4C), allowing for tandem mounting of secondary pumps to streamline the power layout of complex multi-circuit systems.
Low Noise & Silent Operation: Optimized valve plate discharge grooves effectively suppress fluid pulsations, maintaining excellent operational quietness even during high-speed operation at displacements exceeding 100cc.
Flexible Housing & Shaft Configurations: Offers a vast array of spline shafts and flange options, ensuring seamless compatibility with various major mobile machinery powertrains.
