Danfoss H1P Axial Piston Pump
Variable Displacement Power for Demanding Closed-Circuit Applications
Always verify the complete H1P model code before ordering a replacement pump.
Built for High-Performance Mobile Hydraulics
The Danfoss H1P axial piston pump is a variable displacement pump designed for closed-circuit hydraulic systems. It converts mechanical input power into controlled hydraulic flow and pressure, making it a key power source for modern mobile machinery.
The H1P platform is designed around a common architecture with a broad displacement range and multiple control options. This allows machine manufacturers and hydraulic system integrators to configure the pump according to different speed, torque, power and control requirements.
According to Danfoss, the H1P family is suitable for hundreds of mobile applications and is designed to support efficient installation, expanded functionality and reliable operation in demanding off-highway environments.
H1P Performance Range
Technical values are configuration-dependent. The H1P 045/053, 060/068, 069/078, 089/100, 115/130, 147/165/180 and 210/250/280 groups have different operating limits. Always verify the exact model code and current Danfoss technical documentation before selection.

Danfoss H1P FAQ
1. What is the Danfoss H1P?
The Danfoss H1P is a variable displacement axial piston pump designed primarily for closed-circuit mobile hydraulic systems. It provides controlled hydraulic flow for propulsion and other high-power machine functions.
2. What H1P displacement sizes are available?
The current H1P product family covers multiple frame sizes, including 045/053, 060/068, 069/078, 089/100, 115/130, 147/165/180 and 210/250/280 classes. Exact nominal and maximum displacement values vary by frame.
3. What is the maximum pressure of an H1P pump?
Depending on the frame and configuration, maximum working pressure is typically in the approximately 380 to 450 bar range. The exact pressure rating must be confirmed from the specific model documentation.
4. What controls are available for the H1P?
Depending on the selected configuration, H1P pumps can use Electrical Displacement Control (EDC), Hydraulic Displacement Control (HDC), Forward-Neutral-Reverse (FNR), Automotive Control (AC), Fan Drive Control (FDC) and other control solutions.
5. Is the H1P suitable for excavators?
H1P pumps are primarily designed for closed-circuit mobile hydraulic applications. Whether a specific H1P configuration is suitable for an excavator depends on the excavator's hydraulic architecture, duty cycle, pressure requirements and machine design.
6. Can the H1P replace another Danfoss or Rexroth hydraulic pump?
A direct replacement cannot be determined from displacement alone. Port configuration, mounting flange, shaft, rotation, controls, pressure ratings, charge-pump configuration and overall hydraulic circuit must all be checked before selecting a replacement.
7. What information should I provide when purchasing an H1P?
International buyers should provide the complete model code, frame size, displacement, rotation direction, control type, mounting specification and shaft configuration. A clear nameplate photograph can significantly improve model identification.
8. Why is hydraulic cleanliness important for the H1P?
Axial piston pumps operate with close-tolerance components, so hydraulic fluid cleanliness, correct filtration and proper maintenance are important for minimizing wear and maintaining reliable performance.
Need a Danfoss H1P Replacement Pump?
For accurate H1P sourcing, provide the complete pump model code or nameplate information. This allows the supplier to verify displacement, rotation, controls, mounting, shaft, charge pump and pressure configuration before quotation.
