The Rickmeier R65/630FL-Z is a high-performance external gear pump manufactured by RICKMEIER, a German company established in 1914. It belongs to the category of rotary positive displacement pumps. Its core function is to achieve continuous delivery of liquid media through gear meshing, making it suitable for high-viscosity fluids and high-pressure applications. The series employs a helical gear design, significantly reducing the risk of cavitation and enhancing operational stability.
Structural Optimization
Double-circular arc sinusoidal curve tooth profile: Compared to traditional involute gears, this design reduces tooth surface wear and liquid trapping, achieving low noise (noise reduction design), long service life, and high efficiency.
Application of helical gears: The enclosed volume remains almost unchanged during meshing, preventing cavitation caused by local vacuum and protecting the gear surfaces.
Compact and lightweight design: Dimensional optimization reduces weight by up to 30% while increasing displacement by 40%.
Performance Advantages
High-pressure and high-viscosity resistance: The maximum operating pressure reaches medium-pressure levels (4–32 MPa), accommodating high-viscosity media such as waste oil, hydraulic oil, and diesel fuel (the viscosity range is not disclosed but supports heavy oils and polyethylene glycol, among others).
Strong self-priming capability: It can automatically exhaust air and quickly fill the pipeline with liquid.
High efficiency and energy saving: Optimized gear design improves volumetric and mechanical efficiency, reducing energy consumption.
Reliability Design
Flexible coupling: Compensates for installation errors, requiring motor-pump coaxiality to be <0.1mm and a tilt angle ≤1°.
Wear-resistant materials: The housing is specially treated to enhance durability, and the worn drive shaft can be repaired by replacing the bushing.
