Advanced Performance Technology
Pressure Stability
Rubber deformation increases wear and reduces holding pressure inside the pump chambers, which can lead to material backflow inside the stator.
The R7-3 stator is engineered with optimized geometry and uniform rubber wall thickness to ensure stable chamber pressure and reliable conveying performance.
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 service life.
Maintenance-Free Ready-to-Go System
The R7-3 stator is supplied with pre-set tension, allowing immediate use after installation without additional adjustment.
This ensures:
- Fast installation
- Reduced maintenance requirements
- Stable pumping performance across a wide operating range
Applications
The R7-3 is suitable for:
- Earth-moist loam plaster
- Masonry mortar
- Floor leveling compounds
