The R65/500 FL-Z-DB-SO is a high-performance external gear pump developed by Germany's RICKMEIER company, specifically designed for industrial hydraulic systems and demanding operating conditions. Its core advantages lie in its low-noise operation, high durability, and modular compatibility, making it particularly suitable for applications with stringent reliability requirements, such as in marine and heavy industry settings.
Low Noise and Efficient Fluid Guidance
Noise Reduction Technology: The special tooth profile structure combined with a short, straight fluid channel design significantly reduces eddy currents and cavitation, resulting in operating noise levels below industry standards (especially suitable for sensitive environments such as ship cabins).
Suction Performance: The optimized gearbox structure ensures stable liquid suction capabilities under high vacuum conditions, with an inlet pressure adaptation range of -0.4 to +0.5 bar.
Adaptability to Extreme Operating Conditions
Material Strength: The gear shaft undergoes carburizing and hardening treatment, while the plain bearings are coated with a special layer, supporting dry running (lubrication-free startup) and high-pressure shocks.
Media Compatibility: It is compatible with mineral oils, synthetic hydraulic fluids, and low-lubricity media (such as certain fuels or coolants).
Modularity and Maintenance Convenience
Three-part housing structure supports SAE standard interfaces (e.g., SAE 4"), facilitating easy integration into existing hydraulic circuits.
Seals can be flexibly replaced (standard radial seals, with optional slip ring seals for corrosive media).
Long-Life Design
The composite material plain bearings offer a service life of tens of thousands of hours, while the gray cast iron housing provides excellent corrosion resistance, reducing maintenance costs throughout the entire lifecycle.
