The R45/125 FL-Z-DB16-W-SAE2.1/2-L-P is a high-performance internal gear pump manufactured by Germany's RICKMEIER company, specifically designed for industrial lubrication systems and hydraulic power transmission. Operating on the positive displacement principle, it generates vacuum suction and high-pressure discharge through the rotation of a pair of precisely meshing gears within the pump chamber, ensuring stable and continuous media delivery.
Item Number: 474436
• L-P: Configuration Features (integrated pressure limiting valve, fluororubber seals).
Core Technical Characteristics
Efficient and Compact Design
• Offers a 40% increase in displacement and a 30% reduction in weight compared to similar-sized pumps, making it ideal for installation in space-constrained industrial equipment.
• Optimized gear tooth profile (double-circular arc sine curve) eliminates relative sliding between tooth surfaces, reducing wear and noise while extending service life.
Intelligent Safety Protection
• Integrated Pressure Limiting Valve: Automatically opens a return channel when the discharge pressure exceeds the rated value (default 8-10 Bar) to prevent system overload (customizable opening pressure).
• Double-End Seal (DB16): Supports mechanical seals or packing seals, adapting to high-temperature, high-pressure, and corrosive media environments to eliminate leakage risks.
Outstanding Performance Parameters
• Flow Rate: Up to 5000 L/min (depending on media viscosity).
• Operating Pressure: 25 Bar (peak pressure support up to 35 Bar).
• Speed Range: 1200–4000 rpm, with a recommended continuous operating speed of 1800 rpm.
• Media Compatibility: Lubricating oils, hydraulic oils, and vegetable oils (temperature ≤70℃).
