Advanced Performance Technology
Pressure Stability
Rubber deformation increases wear and reduces holding pressure inside the pump chambers, leading to material backflow inside the stator.
The R8-3 stator is engineered with optimized geometry and uniform rubber wall thickness to ensure stable chamber pressure and reliable conveying performance under demanding operating conditions.
Optimized Operating Temperature
Friction generates heat that negatively affects stator rubber. The optimized rubber compound and precise manufacturing improve heat dissipation and reduce operating temperature during continuous operation.
Uneven rubber wall thickness can reduce heat transfer efficiency and accelerate wear — therefore, precision manufacturing is essential for long-term durability.
Adjustable Tension & Pump Operating Range
The stator tension can be manually adjusted using screws, allowing professional users to fine-tune pump performance according to the material and application.
This enables:
- Optimized pressure control
- Adaptation to different materials
- Extended stator service life through re-tensioning
- Flexible operation across a wide working range

The R8-3 is suitable for:
- Masonry mortar
- Thin screed
- Floor leveling compounds
