The Danfoss LR Series represents the ultra-compact segment of the renowned Series 45 open-circuit hydraulic pump family, specifically optimized within the lightweight Frame L housing. Delivering a precise 25cc displacement per revolution, this variable pump utilizes a single-servo piston design combined with a cradle-type swashplate running on polymer-coated bearings. It provides outstanding power density and exceptional self-priming speeds, making it an excellent fluid power choice for modern compact industrial machinery.
We support precision aftermarket replacement units and comprehensive flow alignment for the entire LR25 framework:
* LRR025 Configuration: Right-Hand / Clockwise (CW) rotation input shaft orientation.
* LRL025 Configuration: Left-Hand / Counter-Clockwise (CCW) rotation input shaft orientation.
* Control Valve Adaptation: Fully configurable with original Load Sensing with Pressure Limiter (LS+PC) dual-spool controls or direct Pressure Compensator (PC) single-spool regulators.
Application Information：
This compact open-circuit hydraulic pump series acts as the reliable power generator across diverse global mobile fleets:
* Independent Fan Drive Systems: Primary high-flow drive pump for independent radiator cooling fans in large mining trucks and earthmovers.
* Compact Construction Equipment: Specialized hydraulic implement loops for skid steer loaders (e.g., matching Bobcat systems) and mini-excavators.
* Aerial Work Platforms: Direct hydraulic power source for boom lifts and scissor lifts (e.g., matching JLG and Genie systems).
* Municipal Vehicles: Core hydraulic supply for asphalt rollers, small trenchers, and street sweeping vehicles.
