Danfoss MPV Series Hydraulic Pump | MPV046, MPV044, MPV035, MPV025 | Variable Piston Pump

Danfoss MPV Series Closed Circuit Axial Piston Variable Displacement Pump

Product Overview: The Sauer-Danfoss MPV series is a line of high-performance axial piston variable pumps specifically engineered for Closed Circuit hydrostatic transmissions. This series is widely utilized in road construction machinery, agricultural equipment, material handling vehicles, and various mid-sized mobile applications. Renowned for its compact installation envelope and highly reliable displacement control, the MPV range—from the specialized MPV046CBAJSBBAAGBBDDABUYGANNN to the standard MPV023—provides precise power distribution in demanding environments.

Key Technical Advantages:

• Highly Integrated Closed-Loop Design: The MPV series integrates a charge pump and system relief valves within the pump housing, significantly simplifying external hydraulic plumbing. This reduces overall vehicle weight and enhances leak-proof security.

• Precise Displacement Modulation: Featuring a swashplate design, the MPV supports multiple control methods. Models like the MPV044 and MPV046 achieve millisecond-fast response times via hydraulic or electronic signals, ensuring smooth transitions between travel and implement functions.

• Optimized for Heavy-Duty Cycles: Engineered for the frequent reversals and high-pressure start-ups typical of mobile machinery. Precision-ground piston groups and port plates maintain exceptional volumetric efficiency even at rated pressures of 350 Bar.

• Flexible Modular Configuration: Offers a vast array of control logic options. Specific configurations, such as the MPV046C…GANNN, are optimized with specialized valve blocks and shaft specifications to ensure 100% compatibility with OEM mounting, minimizing maintenance downtime.

Specific Models & Technical Parameters:

• Core Series: MPV023, MPV025, MPV035, MPV044, MPV046.

• Detailed Configurations: Supports complex codes like MPV046CBAJSBBAAGBBDDABUYGANNN.

• Displacement Range: 23 cm³/rev to 46.3 cm³/rev.

• Pressure Specifications: Rated operating pressure 350 Bar (35 MPa); Peak pressure up to 420 Bar.

• Applications: Road roller travel pumps, paver drives, harvester hydraulic systems, and industrial power units.
