Brand Background: Founded in 1914, Rickmeier is a long-established German industrial pump and valve manufacturer specializing in the research and development of gear pumps, valves, and fluid oil supply systems, renowned for its high reliability and precision craftsmanship.
Model Positioning: The R45/80 FL-Z belongs to the medium-displacement gear pump series, featuring efficient transmission and long-life design, suitable for medium- to high-pressure operating conditions.
Core Innovation: It adopts a double-circular-arc sine curve tooth profile (unlike traditional involute gears), eliminating relative sliding between tooth surfaces during meshing, reducing wear, and achieving low-noise, high-stability operation.
Structural Design
Compact and Simple: Without suction/discharge valve structures, it ensures uniform flow and low failure rates.
Optimized Sealing: Supports two types of shaft end seals—mechanical seals or packing seals—to accommodate different media requirements.
Safety Protection: Integrated with a differential pressure safety valve (overload pressure set at 1.5 times the rated value) to prevent overload damage.
Performance Characteristics
Efficient and Stable: Flow range of 0.045–30 m³/h, maximum working pressure of 25 bar, and rotational speed up to 3000 rpm.
Media Compatibility: Suitable for waste oil, diesel, gear lubricants, emulsions, etc., with a viscosity range of 5–20,000 mm²/s.
Strong Self-Priming Capability: Effectively sucks in fluids under negative pressure conditions, reducing the risk of cavitation.
Enhanced Durability
The drive components undergo carburizing and hardening treatment, and the bearings feature dry-running characteristics, extending service life by over 30%.
Seals are available in NBR (-25°C to 80°C) or FKM (-25°C to 150°C) to withstand extreme temperatures.
