The R45/100FL-Z/137L is a high-pressure external gear pump from Germany's RICKMEIER company's R45 series, classified as a positive displacement pump.
Efficient and Low-Loss Performance
Precision Gear Technology: Features a double-circular-arc sinusoidal tooth profile design, ensuring no relative sliding between tooth surfaces during meshing, reducing wear, and achieving an efficiency of over 90%.
High-Pressure Capability: Maximum operating pressure reaches 315 bar (some variants support 350 bar), with a wide flow range (approximately 200 L/min at 2000 rpm).
Low-Noise Operation: Optimized fluid channels and tooth profiles result in noise levels below 75 dB(A), suitable for noise-sensitive environments.
Durability and Low Maintenance
Materials and Processes:
Housing: EN-GJL-250 gray cast iron (GG-25), corrosion-resistant.
Gears: Surface-hardened steel (16MnCrS5), quenched for wear resistance.
Sealing System: Standard NBR radial shaft seals, with optional FKM fluororubber seals (resistant to high temperatures/corrosive media), supporting short-term dry running.
Bearing Technology: P10/DU-type composite plain bearings with special coatings, offering a lifespan increased by over 30%.
Modularity and Compatibility
Standardized Interfaces: Supports SAE flange interfaces (e.g., SAE 2), with a nominal bore diameter of 80mm, compatible with mainstream hydraulic systems.
Optional Functional Modules: Some models integrate pressure relief valves (e.g., DB16), with adjustable pressure settings (e.g., 10–16 Bar) to prevent system overpressure.
