The Danfoss KRR Series represents the high-efficiency, compact displacement segment within the professional Series 45 (K Frame Platform) family of variable displacement axial piston pumps. Engineered explicitly for space-constrained mobile loops, boom lifts, and high-pressure auxiliary systems, these Right-Hand (Clockwise) rotating pumps deliver excellent power-to-weight density. Built with specialized low-noise end caps and optimized valve plates, the KRR series ensures quiet, smooth performance underconstant cycling.
We support precision aftermarket replacement units and comprehensive flow alignment for the entire KRR framework:
* KRR038 Model: 38 cm³/rev displacement, optimized for precise auxiliary lift lines and compact aerial platforms.
* KRR045 Model: 45 cm³/rev displacement, engineered for mini-excavator main oil lines and municipal sweepers.
* Control Valve Adaptation: Fully configurable with original Load Sensing (LS) 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 vocational fleets:
* Aerial Work Platforms: Direct hydraulic source for boom lifts and scissor lifts (e.g., matching JLG and Genie systems).
* Compact Construction Equipment: Specialized hydraulic implement loops for mini-excavators, small wheel loaders, and skid steers.
* Municipal & Road Maintenance: Primary drive unit for asphalt pavers, trenchers, and street sweeping vehicles.
* Industrial Fan Drives: Dedicated fluid power source for independent radiator fan cooling systems on mobile machinery.
