H1P series

Main advantages and scope of application of Sauer-Danfoss H1P series hydraulic pumps

The Sauer-Danfoss H1P axial piston pump series is one of the most advanced solutions for closed-loop hydrostatic transmissions. Designed to meet the high demands of modern mobile applications, these pumps combine high performance, compactness and exceptional flexibility.

Main technical features

Sauer-Danfoss H1P series hydraulic pumps are variable displacement pumps operating on the rotary vane principle. Their design incorporates a number of engineering solutions that define their key characteristics:

• High working pressure: Capable of operating stably at pressures up to 480 bar, which allows transmitting high power with compact dimensions.
• Wide range of working volumes: The H1P line covers a wide range of sizes (from 45 to 280 cm³/rev), which allows you to choose the optimal pump for machines of different power.
• Integrated pumping system: The built-in booster pump ensures stable operation of the closed circuit, its cooling and filtration.
• Flexible control systems: The H1P series supports a variety of control types, including:
  • Electroproportional control (EP): Provides precise and smooth control of the machine's speed and direction.
  • Hydraulic control (HC): A simple and reliable solution for less complex systems.
  • Load sensing control (LS): Allows you to optimize the operation of the hydraulic system, reducing energy losses.
• Modular design: Allows easy integration of additional valves and tandem pumps, creating complex hydraulic systems.
• High specific power: Compact design and optimized construction provide one of the best power-to-weight ratios on the market.

Key benefits for manufacturers and equipment operators

Using Sauer-Danfoss H1P series hydraulic pumps provides a number of significant advantages:

1. Increased productivity and efficiency: High efficiency (up to 95%) reduces energy losses, leading to reduced fuel consumption and increased overall machine performance.
2. Reliability and durability: Robust design, optimized bearing units and an improved lubrication system ensure a long service life even in the most difficult operating conditions.
3. Compactness and ease of integration: The small dimensions of the pump simplify its layout in the limited space of the engine compartment, and standardized mounting flanges and ports facilitate installation.
4. Precision and control: Modern control systems provide excellent machine response to operator actions, which increases work accuracy and comfort.
5. Global platform: The H1P series is designed as a global product, simplifying logistics and servicing of equipment sold in different markets.

Scope of application
