The R65/400 FL-Z-DB25-W-SAE4-R is a high-displacement external gear pump from RICKMEIER in Germany, specifically designed for conveying high-viscosity media such as lubricating oils and fuels. Its core advantage lies in its modular three-part housing structure, which supports flexible customization of interfaces and sealing solutions, making it suitable for medium- to high-pressure applications in industrial hydraulics and lubrication systems.
Item Number: 330272-6
Core Features
High-Strength Structure and Durability
Housing Material: Gray cast iron housing paired with a hardened steel gearbox, offering wear and corrosion resistance.
Bearing Design: Multi-component plain bearings with a special coating support brief dry running, extending service life.
Sealing System: Standard radial shaft seal (pressure-resistant up to ≤6 bar), with optional mechanical seal (pressure-resistant up to ≤25 bar).
High-Efficiency Fluid Performance
Displacement and Flow Rate: Displacement ranges from 112–230 cm³ per revolution, with a maximum flow rate of 690 L/min (requires matching rotational speed).
Low-Noise Operation: Optimized gear tooth profiles and fluid channels reduce cavitation and vibration.
Self-Venting Capability: Automatically expels gas from the suction line, reducing the risk of idle running.
Modular Configuration
Interface Standard: SAE4 flange (high-pressure compatible), ensuring pipeline sealing integrity.
Drive Shaft Type: Straight spline shaft (Z-type), compatible with standard motors.
Special Suffixes:
DB25: Integrated pressure relief valve (pressure set at 25 bar) to prevent overloading.
W: May indicate high-temperature-resistant seals or special materials (requires confirmation).
Environmental Adaptability
Temperature Range: The standard version supports continuous operation at 80°C, with momentary tolerance up to 120°C; for high-temperature scenarios, heat-resistant seals or couplings are required.
Media Compatibility: Suitable for heavy oils, diesel, and lubricating oils (with a wide viscosity range), avoiding strongly corrosive or media containing hard particles.
