Product Description
Sauer-Danfoss Series 45 (KRL/KRR) Axial Piston Variable Pumps
Product Overview: The Sauer-Danfoss Series 45 variable axial piston pumps are high-performance solutions tailor-made for open-circuit systems. As the core members of the 45cc displacement range, the KRL045 (CCW) and KRR045 (CW) are widely utilized in applications demanding maximum operational efficiency and precise control. Featured models include the KRL045DLB18…. Utilizing a precision swashplate design coupled with advanced LS (Load Sensing) and PC (Pressure Compensation) logic, these pumps sense actuator demand in real-time. By delivering only the required flow and pressure, they drastically reduce energy waste and heat generation, making them the premier power source for excavators, forklifts, and agricultural machinery.
Key Technical Advantages:
Advanced Load Sensing (LS) Control: Dynamically matches system flow requirements, eliminating unnecessary overflow losses and significantly boosting the fuel economy of the entire machine.
Superior Power Density: The compact housing integrates large-volume rotating groups, maintaining exceptional structural stability even under a continuous 310 Bar workload.
Low Noise & Vibration: Optimized 9-piston rotating groups and suction port designs dampen fluid ripples, ensuring superior quiet-running performance in factory or mobile cabin environments.
Full Lifecycle Reliability: Critical wear components undergo specialized hardening, optimized for longevity in harsh construction and mining environments characterized by high dust and vibration.
Flexible Installation: Supports diverse shaft specifications (Splined/Keyed) and flange options, including Through Drive capability for tandem mounting of auxiliary pumps.
Detailed Models & Parameters:
Core Series: Sauer-Danfoss Series 45 (Frame K).
Model Keywords: KRL045, KRR045, KRL038, KRR025.
