Product Number: 330033-2
The R65/500-FL-Z-W-SAE4-R is a high-pressure external gear pump from Germany's RICKMEIER company, belonging to its R5 series and classified as a positive displacement pump.
Efficient and Low-Loss Performance
Precision Gear Technology: Features a double-circular-arc sinusoidal tooth profile, ensuring no relative sliding between tooth surfaces during meshing, resulting in minimal wear and an efficiency exceeding 90%.
High-Pressure Capability: Maximum operating pressure reaches 315 bar (with some operating conditions supporting 350 bar), and it offers a wide flow range (approximately 105 L/min at 1450 rpm).
Low-Noise Operation: Optimized fluid channels and tooth profiles reduce noise levels to below 75 dB(A), making it suitable for noise-sensitive environments.
Durability and Low Maintenance
Materials and Processes:
Housing: EN-GJL-250 gray cast iron (GG-25), corrosion-resistant.
Gear Shaft: Quenched surface-hardened steel (16MnCrS5), resistant to wear.
Sealing System: Standard radial shaft seals (with NBR/FKM options available), supporting mechanical seals (hard carbon/SiC), and resistant to high-temperature/corrosive media.
Bearing Technology: P10/DU-type composite plain bearings with special coatings support short-term dry running (≤20 minutes) and offer a 30% increase in lifespan.
Modularity and Compatibility
SAE4 Flange Interface: Standardized design for compatibility 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.
