Danfoss MPT-046 Series Pump | MPT-046-C-E-C-C-D | Axial Piston Variable Pump

Danfoss MPT-046 Series Axial Piston Variable Displacement Pump

Product Overview: The Danfoss MPT-046 series is an axial piston variable displacement pump specifically engineered for mid-power hydrostatic transmission systems. As a benchmark in the 46cc (46cm³/rev) displacement class, it integrates a charge pump, high-pressure relief valves, and sophisticated control mechanisms into a single unit. Featured models like the MPT-046-C-E-C-C-D… provide stepless speed regulation and smooth directional reversal for mobile machinery. With its highly modular design, this pump can be precision-configured for various control requirements (mechanical or hydraulic), making it the premier choice for road roller drives, auxiliary systems in drilling rigs, and specialized agricultural equipment.

Key Technical Advantages:

• Fully Integrated Closed-Circuit Design: Built-in charge pump and charge relief valves simplify hydraulic plumbing, enhancing overall power density and system response.

• Precision Bi-Directional Flow Control:

  • MPT-046 allows for seamless flow transition from forward to reverse by adjusting the swashplate angle.

  • The BHH-AB-D-DD specs represent factory-optimized settings for threshold points, centering springs, and damping orifices.

• Compact High-Pressure Reliability: Rated for continuous operation at 210 Bar with peak capabilities reaching 350 Bar (5075 PSI), ensuring structural integrity in a lightweight envelope.

• Outstanding Durability & Low Maintenance: Features reinforced bearing systems and low-friction rotating groups, specifically designed for harsh outdoor environments characterized by high vibration and frequent duty cycles.

• 100% OEM-Standard Compatibility (Smart Code):

  • The complex MPT-046-C-E…ANN configuration code ensures that flanges, shafts, charge displacements, and control response times perfectly match original OEM equipment.
