Model D1P130 / D1P145 / D1P193 / D1P260 are heavy-duty variable displacement axial piston pumps for open circuits, belonging to the D1P Series, with customizable internal production coding for different specification variants. Adopting the D1P Series proprietary swash plate piston displacement technology and the robust spherical valve plate design that prevents cylinder block tilting, these pumps serve as direct aftermarket replacements for original OEM pumps of the same D1P specifications.

The D1P Series represents premium high-efficiency piston pumps, delivering stable high flow and high-pressure output (350 bar continuous working pressure, 400 bar peak pressure) within a compact casing size. Under severe service environments including open-pit mining, construction cranes, concrete pumping, and road construction projects, these pumps feature outstanding pressure resistance and long-term operational durability, acting as the preferred core hydraulic power source for heavy-duty machinery such as small and medium excavators, roadheaders, crawler cranes, and concrete pump trucks. Designed with standard SAE heavy-duty mounting standards and multi-bolt fixed flange layout, the entire series can withstand frequent heavy shock loads and continuous mechanical vibration, adapting to the harsh operating conditions of various mobile equipment.

This pump range supports customized structural variants (such as shaftless/semi-shaftless configurations for integrated transmission), purpose-built to pair with customer-assembled planetary gear reducers and integrated hydraulic transmission assemblies. The customized version eliminates the conventional independent output shaft, and directly engages with the matched gear set of peripheral drive systems through custom spline sleeves and dedicated tooth profiles. It is ideal for hydraulic systems restricted by narrow installation space or mechanical equipment adopting integrated modular and lightweight design concepts, especially suitable for eHydraulic power module applications in electrified construction machinery.

1. Integrated Structure Design - An Ideal Choice For Integrated Drive & Electrified Systems

Danfoss D1P Series Hydraulic Piston Pump D1P130 / D1P145 / D1P193 / D1P260 adopts optimized integrated structure design, which is a dedicated configuration for integrated drive and electrified hydraulic systems:

Integrated connecting structure: Custom spline and shaft end design are adopted. External radial loads are shared by the matching motor or reducer assembly on the user's equipment; Direct integration with gear reducers & drive motors: The pump can be directly mounted to planetary gearboxes or Editron drive motor assemblies without additional support bearings or couplings, perfectly matching the eHydraulic power module; Compact axial dimension: The streamlined pump body greatly shortens the overall axial length, making it particularly suitable for equipment with extremely limited installation space; Easy installation: Standard SAE heavy-duty mounting dimensions and multi-bolt fixed flange layout enable seamless matching with user equipment and ensure excellent concentricity during operation.

2. D1P Series - High Performance Open Circuit Axial Piston Hydraulic Pump

The Danfoss D1P Series stands for premium high-performance axial piston hydraulic pumps for open circuits in Danfoss' product lineup:

High power density: Delivers stable high flow and high-pressure output within a compact housing; Advanced swash plate & cylinder block assembly: Equipped with optimized swash plate bearings and reinforced cylinder block structure, it achieves higher mechanical efficiency and strong resistance to shock and vibration; Spherical valve plate flow distribution technology: The proprietary spherical valve plate prevents cylinder block tilting, features automatic wear compensation, maintains excellent volumetric efficiency in long-term operation and reduces pressure loss effectively; Harsh condition adaptability: Capable of working stably under high continuous pressure (350 bar) and peak pressure (400 bar), adapting to different viscosity hydraulic oils and frequent displacement adjustment. It performs reliably on construction, mining, marine and road machinery under severe working conditions.
