The R65/500 FL-Z-W-SAE4-R-P is a high-performance external gear pump manufactured by Germany's RICKMEIER company, specifically designed for industrial fluid transfer applications. Its core advantages lie in its structural robustness, low-noise operation, and high adaptability, making it suitable for demanding operating conditions such as lubrication systems, hydraulic power units, and fuel transfer. The pump features a modular design and supports customized interfaces to meet the special requirements of industries such as marine, energy, and chemical engineering.
Optimized Structure and Materials
• Housing: Cast from gray cast iron, it is corrosion-resistant and impact-resistant, with the option of stainless steel coating to enhance media compatibility.
• Drive Components: Carburized steel hardened and surface-nitrided for improved wear resistance, with an expected service life of ≥18,000 hours.
• Bearing System: Large-sized composite material sliding bearings with special coatings provide excellent dry running characteristics, reducing the risk of sudden failures.
Fluid Performance Optimization
• Low-Noise Design: Short straight flow passages and a 17° pressure angle-corrected tooth profile reduce fluid turbulence, resulting in noise levels 15%-20% lower than comparable products, particularly suitable for foam oil transfer.
• High-Efficiency Self-Priming Capability: A suction vacuum of up to -0.6 bar (instantaneous at startup) eliminates the need for pre-filling and accommodates complex piping layouts.
Sealing and Safety
• Shaft Seal Options: Standard radial shaft seals (pressure-resistant ≤6 bar), with optional mechanical seals supporting high-pressure conditions up to 25 bar; fluororubber material compatible with mineral oils, water-glycol, and synthetic lubricants.
• Integrated Pressure Limiting Valve: Optional spring-loaded pressure limiting valves (e.g., models with the "-P" suffix) prevent system overload and protect the pump structure.
