Danfoss MPV Series Pump | MPV046, MPV044, MPV035 | Hydraulic Vibration Pump

Danfoss MPV Series High-Pressure Hydraulic Vibration Pump

Product Overview: The Danfoss MPV series represents a premier line of axial piston variable displacement pumps specifically engineered for medium-power closed-circuit hydraulic systems. This series is the industry standard for vibratory systems in single and double drum road rollers. Covering displacements from MPV025 to the flagship MPV046, including specialized configurations like MPV046CBBKSB… and MPV046CBAJSB…, these pumps deliver exceptional hydrostatic performance. Designed for high-frequency start-stop cycles, the MPV series provides a superior power-to-weight ratio and compact footprint, making it the preferred choice for top OEMs such as Bomag, Dynapac, and SANY.

Key Technical Advantages:

• Precision Variable Control: Features the classic slipper-type axial piston design, supporting various control options (MDC or EDC) to ensure smooth vibration ramp-up and frequency stability.

• Closed-Circuit Optimization: Rated for continuous operation at 350 Bar with peak capabilities up to 400 Bar, easily handling the massive load spikes encountered during initial vibration activation.

• Integrated Component Architecture: Includes built-in charge pumps, high-pressure relief valves, and charge check valves within the main housing, simplifying system plumbing and reducing leak points.

• Heavy-Duty Bearing System: Specially reinforced for the high-vibration and high-impact environments typical of road construction, significantly extending service life under heavy-duty cycles.

• 100% OEM System Compatibility:

  • Extensive smart codes (e.g., MPV046…ABJJAB) define exact displacement limits, charge pump sizes, and pressure settings, ensuring a seamless “plug-and-play” replacement for original equipment.
