Product Overview
Model ERR100 / ERR130 / ERR147 (ER-R Right-hand / ER-L Left-hand) are heavy-duty variable displacement axial piston pumps designed for open hydraulic circuits, belonging to the ERR & ERL Series. This product line adopts dedicated internal coding systems to distinguish various specification variants. Featuring the mature swash plate variable displacement technology and wear-resistant valve plate structure that effectively prevents cylinder block deflection, these pumps serve as ideal direct aftermarket replacements for original OEM pumps with identical specifications of the ERR/ERL platform.
The ERR & ERL Series are high-performance, high-efficiency piston pumps. They deliver stable large flow and high-pressure output within a compact housing, with 280 bar continuous working pressure and 300 bar intermittent peak pressure (320 bar maximum shock pressure). Operating reliably in harsh working environments including open-pit mining, construction cranes, concrete delivery and road construction projects, the pumps exhibit excellent pressure resistance and long-term operational durability. They are the preferred core hydraulic power units for heavy-duty machinery such as small and medium excavators, roadheaders, crawler cranes, concrete mixer trucks, road rollers and drilling rigs. Equipped with standard SAE heavy-duty mounting specifications and multi-bolt fixed flange layout, the full series can withstand frequent heavy impact loads and continuous mechanical vibration, fully adapting to the rigorous operating conditions of diverse mobile machinery and equipment.
This pump series supports customized structural configurations, including shaftless and semi-shaftless designs for integrated transmission. These tailored versions are specially developed to match customer-assembled planetary gear reducers and integrated hydraulic transmission assemblies. The customized pumps remove the traditional independent output shaft, and connect directly with the gear sets of peripheral drive systems via custom spline sleeves and dedicated tooth profiles. They are perfectly suited for hydraulic systems with limited installation space, as well as mechanical equipment adopting integrated modular and lightweight design concepts. This range is especially applicable to e-Hydraulic power module solutions for modern electrified construction machinery.
Core Advantages
Integrated Structure Design - An Ideal Choice For Integrated Drive & Electrified Systems
Danfoss ERR & ERL Series Hydraulic Piston Pump ERR100 / ERR130 / ERR147 (ER-R Right-hand / ER-L Left-hand) 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 Danfoss Editron drive motor assemblies without additional support bearings or couplings, perfectly matching the eHydraulic power module for electrified machinery; Compact axial dimension: The streamlined cast iron 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 and stable operation during long-term running.
ERR & ERL Series - High Performance Open Circuit Axial Piston Hydraulic Pump
The Danfoss ERR & ERL Series stands for premium high-performance axial piston hydraulic pumps for open circuits in Danfoss' Series 45 product lineup:
High power density: Delivers stable large flow and high-pressure output within a compact housing; Advanced swash plate & cylinder block assembly: Equipped with dual servo piston controlled swash plate and polymer-coated journal bearings, plus reinforced 9-piston cylinder block structure, it achieves higher mechanical efficiency and strong resistance to shock and continuous mechanical vibration; Bi-metallic valve plate flow distribution technology: The proprietary bi-metallic valve plate effectively prevents cylinder block tilting, features automatic wear compensation, maintains excellent volumetric efficiency in long-term operation and reduces internal pressure loss and operating noise effectively; Harsh condition adaptability: Capable of working stably under high continuous pressure (280 bar) and intermittent peak pressure (300 bar, max 320 bar shock pressure), adapting to hydraulic oils with different kinematic viscosities and frequent displacement adjustment. It performs reliably on construction, mining, marine and road machinery under severe working conditions.
