The Rickmeier R45/100 FL-Z-W-SAE2-R is a high-pressure gear pump manufactured by Germany's RICKMEIER company, representing a large-displacement model (with a displacement of 100 cm³/rev) within its R45 series. The pump features a modular design optimized for industrial hydraulic systems, lubrication systems, and scenarios involving the transfer of high-viscosity media. It is compatible with a variety of media, including mineral oils, synthetic oils, diesel fuel, and cutting fluids, and is suitable for demanding operating conditions involving high temperatures, high pressures, and prolonged continuous operation.
Efficient and Stable Delivery
• Gear Technology: Utilizes carburized and hardened steel gear shafts paired with composite material plain bearings, combined with a double-circular-arc sinusoidal tooth profile to achieve meshing without relative sliding. This significantly reduces wear and noise (sound pressure level ≤87 dB(A)), extending service life.
• Flow Accuracy: A short, straight flow channel design enhances oil suction efficiency, maintaining stable flow output even under a working pressure of 25 bar, with a volumetric efficiency exceeding 95%.
Resistance to Harsh Environments
• Materials and Sealing:
◦ Housing Material: Gray cast iron EN-GJL-250 (with an optional ductile iron EN-GJS-400-15 option).
◦ Sealing Options: Standard radial shaft seals (RWDR), with optional slip ring seals (GLRD) or magnetic couplings (MK) for zero leakage; supports FKM seals for temperature resistance up to 150°C.
• Pressure Range: Inlet pressure support ranges from -0.4 to 0.5 bar (RWDR), with a maximum outlet pressure of 25 bar, accommodating media containing gas (gas content ≤10%).
Modularity and Compatibility
• Standardized Interfaces: SAE2-R flange connections enable rapid integration into hydraulic piping systems, compatible with SAE, DIN, and imperial thread interfaces.
• Functional Expansion: Optional integrated pressure-limiting valves (with a pressure range of 1–25 bar) prevent damage from overpressure; supports bidirectional rotation (R/L/C-UNI) configurations.
