Sauer Danfoss MPT044 & MPV046 Pump | MPT044DC, MPV046CB | 210 Bar Hydrostatic Piston Pump

Sauer-Danfoss MPT044 & MPV046 Series Hydrostatic Variable Piston Pump

Product Overview: The Sauer-Danfoss MPT/MPV series is a high-efficiency axial piston variable pump specifically engineered for Closed Circuit hydrostatic transmissions in mid-sized mobile machinery. This series covers two core displacements: 44 cm³/rev (MPT044) and 46 cm³/rev (MPV046). MPT pumps typically feature integrated charge pumps and various control mechanisms, delivering smooth and precise power output under a continuous operating pressure of 210 Bar. Models like the MPT044DC and MPV046CB are the preferred power sources for vibratory rollers, agricultural harvesters, and auxiliary circuits in construction equipment due to their compact housing and superior power-to-weight ratio.

Key Technical Advantages:

• Efficient Closed-Loop Architecture: Fluid circulates directly between the pump and motor, offering high energy efficiency, rapid reversal response, and powerful hydrostatic braking capabilities.

• Integrated Compact Design: Internally houses the charge pump, high-pressure relief valves, and charge pressure regulators, drastically simplifying external plumbing and minimizing leak points.

• Versatile Control Options (DC/CB):

  • Electro-Hydraulic Proportional Control: Enables integration with microprocessors for smart travel and constant speed management.

  • Hydraulic & Manual Controls: Provide intuitive operator feedback, ideal for simple and robust travel systems.

• Optimized for Harsh Environments: Reinforced rotating groups and heavy-duty bearing designs ensure stable, long-term operation in high-heat, high-dust agricultural and construction sites.

• Highly Customized Suffix Codes: Long codes such as MPT044DC4AZNN… represent precise configurations for specific OEMs (shafts, flanges, charge pump sizes), ensuring 100% “plug-and-play” replacement compatibility.
