The RICKMEIER R65/400FL-Z-W-SAE4-R 330032-4 is an external gear pump manufactured in Germany, belonging to the standard product line of the R5 series. Its design balances high efficiency, durability, and modular adaptability, making it suitable for industrial hydraulic systems, lubrication engineering, and fluid transfer applications. Its core advantage lies in its stable output under a working pressure of 25 bar, with a displacement range covering 2.5–2400 cm³/r and a maximum flow rate of up to 4000 L/min (depending on rotational speed and medium viscosity).
Item Number: 330032-4
Structural Optimization
Three-part Housing Design: Composed of a gray cast iron housing (corrosion-resistant), hardened steel gear shafts, and composite material sliding bearings, it supports rapid customization of interfaces (such as SAE flanges, threaded connections) to meet specific customer piping requirements.
Wear-Resistant Components: The gears are hardened and paired with low-friction radial shaft seals, extending service life and reducing the risk of dry running.
Lightweight Improvements: 30% smaller in volume and 70% lighter in weight compared to previous models, facilitating easy installation and maintenance.
Performance Parameters
Pressure and Flow: Continuous working pressure ≤ 25 bar, with strong peak pressure tolerance; when matched with a rotational speed of 1450 min⁻¹, it efficiently transfers viscous media (such as lubricating oil, fuel).
Medium Compatibility:
Oils: Heavy oil, diesel, lubricating oil, gasoline (requiring copper gears), hydraulic oil, waste oil, etc.
Operating Conditions: Temperature resistance ≤ 300℃ (heat-resistant models required for high temperatures), tolerance for media containing particles/fibers (such as cutting oil, emulsions).
Low-Noise Operation: Optimized gear meshing design ensures sound pressure levels comply with industrial environmental standards (measured ≤ 70 dB at a distance of 1m).
Modular Expansion
Supports multiple sealing options (standard radial shaft seals, optional mechanical seals);
Integrated pressure-limiting valve (optional DBV series) to prevent overload damage.
