Product Description
Danfoss MMF044 & MMF035 Series Variable Hydraulic Piston Pump for Road Rollers
Product Overview: The Sauer-Danfoss MMF series is a range of high-pressure axial piston variable pumps/motors specifically engineered for Closed Circuit systems in road construction machinery, such as rollers, pavers, and cold planers. Renowned for its superior power density and compact footprint, the MMF range—featuring core models MMF044 and MMF035—delivers precise and smooth power for travel drives and vibration systems through highly integrated control logic.
Key Technical Advantages:
High Dynamic Response Control: Models like the MMF044DAFHCDNNN are equipped with advanced variable mechanisms that respond instantaneously to operator commands, ensuring the roller maintains smooth motion during start-up, steering, and vibration transitions to prevent surface marking.
Optimized for Road Machinery Duty Cycles: Specifically reinforced for the frequent reversals and high-frequency vibrations typical of compaction work. Models such as the MMF044DANUABNNN offer exceptional shock resistance, significantly extending service life in high-temperature operating environments.
Compact Integrated Design: The MMF series integrates charge control and relief protection within the pump housing, simplifying the hydraulic plumbing on roller chassis. This not only eases maintenance but also effectively minimizes potential leakage points.
100% Industrial Reliability: Engineered for high-pressure cycles with precision-ground piston groups and port plates. It maintains maximum volumetric efficiency even under full-load operation, contributing to fuel savings and reduced emissions.
Specific Models & Technical Parameters:
Machine Compatibility: Single-drum rollers, tandem rollers, and asphalt pavers.
Core Series: MMF044, MMF035, MMF044D, MMF035D.
Detailed Config Codes: MMF044DAFHCDNNN, MMF044DANUABNNN.
