The Rickmeier R25/20 FL-Z-DB16-W-G1-R is a German-original gear-type positive displacement pump, specifically designed for conveying lubricating oils, fuels, and high-viscosity industrial fluids.
Structure and Materials
Housing: Cast from gray cast iron, featuring high pressure resistance and suitability for industrial environments.
Gears and Drive Shaft: Carburized steel quenched for high hardness and strong wear resistance.
Bearings: Designed with multi-component sliding bearings that support dry running (short-term), extending service life.
Performance Parameters
Operating Pressure: Standard version has an upper limit of 25 bar (high-pressure versions available as options).
Flow Rate Range: Depends on rotational speed, reaching up to 400 L/min (requires matching motor speed).
Media Temperature: Continuous operation ≤80°C, with instantaneous peak values ≤120°C.
Sealing Options: Standard radial shaft seals (NBR material), with mechanical seals (e.g., fluororubber FPM) available as options.
Low Noise and High Efficiency
The straight-through flow channel design reduces flow resistance and the risk of cavitation, with operating noise lower than the industry average.
Volumetric efficiency exceeds 95%, making it suitable for high-viscosity media (such as heavy oil and hydraulic oil).
