I. Product Overview
RICKMEIER is a century-old German brand specializing in hydraulic technology, with a focus on the research and development of high-performance gear pumps. The R46/160-FL-Z-W-SAE2 1/2-R-SO belongs to the R46 series and is an industrial gear pump featuring a modular design. Its core advantages include high efficiency, low noise, and a compact structure, making it suitable for high-pressure and high-flow applications.
II. Core Parameters and Performance
Displacement and Pressure
Displacement range: 112–230 cm³/rev (with a typical displacement of 160 cm³/rev for the R46/160 model).
Operating pressure: The maximum continuous operating pressure is 25 bar, with short-term pressure resistance at the suction port of -0.6 bar (e.g., during startup).
Flow rate: The maximum delivery volume is 690 L/min (dependent on matching rotational speed).
Structure and Materials
Housing: Made of gray cast iron (EN-GJL-250/GG-25), it offers high strength and corrosion resistance, with a two-component RAL 7021 anti-corrosion coating applied to the surface.
Gears and shafts: Constructed from surface-carburized hardened steel (16MnCrS5), they exhibit excellent wear resistance and a long service life.
Bearings and seals:
Lead-free composite sliding bearings support short-term dry running, being environmentally friendly and durable.
Standard FKM material radial shaft seals are included, with options for NBR, HNBR, etc., to adapt to different media.
Environmental Adaptability
Temperature range: The operating temperature for conventional media is ≤80℃. For high-temperature scenarios, heat-resistant seals (e.g., PTFE) are required as options.
Media compatibility: It is compatible with non-strongly corrosive fluids such as lubricating oils, hydraulic oils, diesel fuels, and emulsions.

III. Technical Highlights
Efficient and Low-Noise Design
Optimized tooth profile and flow path: The double-circular-arc sine gear structure reduces trapped oil phenomena, combined with special housing noise reduction treatment, resulting in significantly lower operating noise compared to industry standards.
Anti-cavitation capability: The improved suction flow path design reduces cavitation sensitivity, enhancing stability at high rotational speeds.
Compact and Lightweight
Compared to its predecessor, the R5 series, the R6 series is 30% smaller in volume and 30% lighter in weight for the same displacement, facilitating integration into space-constrained equipment.
Modularity and Compatibility
It is 100% interchangeable with the R5 series, supporting rapid upgrades; expandable seal materials (NBR, PTFE, etc.) and heat-resistant couplings are available to adapt to special operating conditions.
