Core Components
Gears and Bearings:
Gears are made of carburized and hardened steel (16MnCrS5), offering strong wear resistance;
Optimized tooth profile design reduces pulsation, with operating noise ≤70 dB.
Housing and Seals:
Gray cast iron housing (EN-GJL-250) provides pressure and impact resistance;
Standard FKM fluororubber radial shaft seals are included, with optional mechanical seals available (pressure-resistant up to 25 bar).
Modular Design
Three-part housing structure supports customized interfaces (such as special flanges or threads);
100% interchangeable with the R5 series, reducing spare parts costs.
Operating Principle
The gears mesh to form sealed chambers, enabling continuous and pulsation-free delivery through volume changes;
The short straight flow path design enhances suction efficiency and reduces the risk of cavitation.
