The R45/80 FL-Z-R-SO is a high-pressure gear pump representing a century of technological expertise from Germany's Rickmeier, specifically engineered for the conveyance of high-viscosity media and heavy-duty lubrication systems. Its core values lie in the following aspects:
High-Flow Efficient Conveyance: With a displacement of 80 cm³/rev and a flow rate of up to 45 m³/h, it meets the centralized oil supply demands of large-scale equipment in mining, wind power, and other industries.
Industrial-Grade Pressure Resistance: It sustains a continuous working pressure of 250 bar and a peak pressure of 350 bar. The built-in safety valve (denoted by the model suffix -SO) provides overpressure protection (set at 65.4 MPa).
Low-Noise, Long-Life Design: The double-circular-arc sine curve tooth profile achieves zero sliding wear on tooth surfaces. Combined with optimized relief grooves, it ensures pressure pulsation < ±2%, noise ≤ 70 dB(A), and a service life exceeding 20,000 hours.
Triple Anti-Damage Structure:
Hardened Gear Set: The carburized steel surface has a hardness of HRC 60+, resisting abrasion from impurities.
Wide-Area Bearings: Special-coated plain bearings increase the load-bearing area by 40%, ensuring even pressure distribution.
Modular Seal Chamber: The split front cover design allows for shaft seal replacement without disassembling the pump body.
Intelligent Efficiency Optimization:
Self-Priming and Air Exhaust Capability: It automatically empties the suction line, quickly establishing a stable flow rate.
Low-Pressure-Loss Flow Path: The straight-through suction chamber design offers vacuum resistance ≥ 0.3 bar, reducing the risk of cavitation.
