R8-1.5 Rotor Stator Set
Description
R8-1.5 Rotor Stator Set – High-Capacity Pump for Heavy-Duty Applications
The R8-1.5 rotor stator set is a powerful heavy-duty screw pump engineered for applications requiring extremely high conveying capacity, stable pressure performance, and reliable operation with coarse materials.
Designed for professional construction environments, the R8-1.5 delivers outstanding durability, adjustable pressure control, and optimized pumping efficiency even under continuous heavy load.
Made in Germany – built for maximum precision, reliability, and long service life.
Key Features
- Extremely high conveying capacity up to 80 l/min
- Suitable for materials with up to 8 mm grain size
- High wear-resistant high-alloy tool steel rotor
- Rotor with slotted design for optimized performance
- Stator with integrated clamp and 6-way slit
- Adjustable tension system for application-specific setup
- Designed for demanding continuous operation
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 R8-1.5 is engineered for stable chamber pressure and reliable conveying performance, even under high pressure and with abrasive materials.
Optimized Operating Temperature
Friction generates heat that negatively affects stator rubber. The optimized rubber compound and precise stator 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-term durability.
Adjustable Tension & Pump Operating Range
The integrated clamp system allows the stator tension to be manually adjusted using screws.
This enables professional users to:
- Fine-tune pressure performance for specific materials
- Adjust conveying characteristics to application requirements
- Extend stator service life through controlled re-tensioning
The adjustable design makes the R8-1.5 highly versatile for different operating conditions and material types.
