Danfoss ERR & ERL Series Medium-Heavy Duty Variable Piston Pumps

Product Overview: The Danfoss ERR and ERL series are high-performance axial piston variable displacement pumps engineered for the most demanding medium-to-heavy duty open-circuit hydraulic systems. This robust lineup features three primary displacements: 100cc (100B), 130cc (130B), and 147cc (147C). Featured models like the ER-R-130B-LS-28-25-NN-N-3-S1CP deliver unmatched precision. Renowned for its superior power density and accurate control, the ER series is equipped with advanced LS (Load Sensing) and PC (Pressure Compensator) regulators. Its rugged design makes it the premier power source for large road machinery (e.g., pavers), oil exploration drilling heads, and heavy-duty industrial presses.

Key Technical Advantages:

• Intelligent LS Load Sensing Control: Precisely detects load pressure variations and delivers only the required flow and pressure, significantly minimizing energy waste, reducing system heat, and boosting overall operational efficiency.

• Superior Suction Capability: Fluid-dynamically optimized intake channels ensure the pump maintains excellent self-priming performance at high speeds or high altitudes, effectively reducing cavitation risks.

• High-Pressure Durability: Rated for continuous operation at 310 Bar (4500 PSI) with peak capability up to 400 Bar, designed to handle instantaneous shock loads in complex industrial environments.

• Flexible Integration: Available in both ERR (Clockwise/CW) and ERL (Counter-clockwise/CCW) rotations, with standard SAE flange compatibility for seamless integration into various drivetrains.

• Heavy-Duty Bearing Life: Utilizing reinforced bearing groups and high-strength swashplate designs, the ER series is optimized for 24/7 high-load industrial environments, ensuring extended service intervals.
