Danfoss heavy-duty agricultural transporter H1P heavy-duty pump
Danfoss H1P Heavy-Duty Pump for Heavy Agricultural Transport Vehicles
As a core member of Danfoss’ H1 product family, the H1P heavy-duty closed-circuit axial piston pump is specifically engineered to meet the rigorous demands of heavy agricultural transport vehicles. Leveraging decades of Danfoss’ expertise in mobile hydraulics, this pump sets the standard for quality, reliability, and efficiency in high-power agricultural applications, providing robust hydraulic power support for heavy-duty operations such as crop transportation, fertilizer hauling, and farm equipment towing.
Core Advantages for Heavy Agricultural Applications
- Exceptional Power and Pressure Capacity: With a maximum operating pressure of up to 480 bar (6962 psi) and a wide displacement range from 45 cm³ to 280 cm³ per revolution, the H1P pump delivers superior power density to handle the high-load requirements of heavy agricultural transport vehicles, even in harsh field conditions.
- Optimized Efficiency for Reduced Operating Costs: The integrated electro-hydraulic servo system precisely controls hydraulic flow rate and direction with minimal servo pressure, ensuring maximum operational efficiency. Its integrated gerotor charge pump design and pressure-balanced port plates minimize volumetric losses, significantly reducing fuel consumption and total cost of ownership for agricultural operations.
- Compact and Robust Design: Featuring a single swash plate structure and no T-bar, the H1P pump has fewer components, resulting in a compact and lightweight design. This not only simplifies installation in the limited space of agricultural transport vehicles but also enhances durability, capable of withstanding dust, vibration, and temperature fluctuations typical in farm environments.
- Precise Control and High Reliability: Equipped with high-current solenoids, the pump achieves lower control losses and higher resolution, ensuring stable and predictable operation of heavy agricultural transport vehicles. A variety of control options, including Electrical Displacement Control (EDC), Non-Feedback Proportional Electric Control (NFPE), and Forward-Neutral-Reverse (FNR) control, adapt to different operational needs of agricultural transport scenarios.
- Flexible Compatibility: The 280 cc new model maintains the same footprint as the 210 cc and 250 cc versions, enabling easy upgrade and replacement. Standardized connector interfaces and a true clean-side design allow flexible component placement, simplifying integration with the hydraulic systems of various heavy agricultural transport vehicle models.

Application in Heavy Agricultural Transport Vehicles
The Danfoss H1P heavy-duty pump is ideally suited for heavy agricultural transport vehicles, such as large-scale grain transporters, fertilizer transport trucks, and farm equipment carriers. In these applications, the pump often forms a hydrostatic drive system with Danfoss H1B motors (e.g., one pump with four motors configuration), providing powerful and stable driving force for vehicles with full load weights exceeding 30 tons.
Key application advantages in agricultural transport:
- The integrated ISL anti-engine overspeed device effectively controls low-side pressure during downhill or braking, preventing engine overspeed and ensuring driving safety in hilly farmland areas.
- The pump’s high power density and efficient operation ensure sufficient power output even when vehicles are transporting heavy loads on uneven farm roads, improving transportation efficiency.
- Compatibility with Danfoss PLUS+1® electronic control system enables precise control of vehicle speed and auxiliary functions, reducing operator fatigue and enhancing operational accuracy.
- Robust construction and excellent environmental adaptability ensure reliable performance in dusty, humid, and extreme temperature conditions commonly encountered in agricultural operations.
