Product Overview
▔▔RICKMEIER Gear Pumps operate on the proven external gear principle. As the gear set rotates inside the housing, vacuum is created at the suction side, pulling liquid into the pump. The medium is transported along the housing walls in the gaps between the gear teeth and discharged under pressure at the outlet side.
Key Advantages
▔▔-
Exceptional Operational Reliability: Engineered for long service life with minimal maintenance downtime, even under continuous industrial operation.
Low Noise Emissions: Advanced tooth geometry and precision casing design significantly reduce noise and pulsation levels.
High Efficiency: Optimized gear profiles ensure maximum volumetric and mechanical efficiency, reducing energy consumption.
Flexible Customization: Available with multiple sealing options (e.g., shaft seal rings, mechanical seals, magnetic couplings) and integrated pressure relief valves.
Wide Viscosity Range: Capable of handling fluids across a broad range of viscosity classes, from light oils to heavy synthetic lubricants.
