R7-1.5 Stator Design
The standard R7-1.5 stator features a grooved design, requiring an external clamp system for operation.
Alternative versions are also available:
- Maintenance-free stator (without grooves)
- Integrated clamp stator
The standard stator is supplied in brown.
Please contact us if you require a customized configuration for specific materials or applications.
Pressure Stability
Rubber deformation increases wear and reduces holding pressure inside the pump chambers, leading to material backflow within the stator.
The R7-1.5 is engineered for stable chamber pressure and reliable conveying performance, even under high load and with abrasive materials.
Optimized Operating Temperature
Friction generates heat that negatively affects the stator rubber. The optimized rubber compound and precise geometry 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.
Adjustable Tension System
The grooved R7-1.5 stator allows manual tension adjustment using external clamping screws.
This enables professional operators to:
- Adjust pump pressure to specific materials
- Optimize performance for different applications
- Extend stator service life through controlled tension adjustment
