Advanced Performance Technology
Pressure Stability
Rubber deformation increases wear and reduces holding pressure inside the pump chambers, which can cause material backflow in the stator.
The D7-2.5 stator features optimized geometry and uniform rubber wall thickness for stable chamber pressure and reliable conveying performance.
Optimized Operating Temperature
Friction generates heat that negatively affects stator rubber. The carefully selected rubber compounds and efficient heat dissipation reduce operating temperature and help extend service life.
Maintenance-Free Ready-to-Go System
The stator is supplied with pre-set tension, allowing immediate use after installation without additional adjustment. This minimizes downtime and simplifies operation on site.
Applications
The D7-2.5 is suitable for:
- Gypsum / gypsum-lime plaster
