D8-1.5 Rotor Stator Set
Description
D8-1.5 Rotor Stator Set – High Output Performance with Integrated Clamp
The D8-1.5 rotor stator set, also known as the D5 Short with integrated clamp, is a powerful screw pump solution designed for demanding plastering, mortar, and screed applications requiring high conveying capacity and adjustable stator tension.
With its integrated clamping system, robust construction, and high output performance, the D8-1.5 is ideal for professional users who require maximum flexibility and reliable operation under varying material conditions.
Made in Germany – engineered for durability, precision, and professional construction site performance.
Compatible Machine Types
The D8-1.5 is compatible with:
- PFT G4
- PFT Ritmo XL
- PFT Swing L
Key Features
- Also known as the D5 Short with integrated clamp
- High conveying performance up to 38 l/min
- Integrated clamping system for adjustable tension
- Available with green or brown stator
- Suitable for demanding and abrasive materials
- Rotor available in cast iron or high-alloy tool steel
- Ideal for professional plastering and screed applications
Integrated Clamp System
The D8-1.5 stator features an integrated clamping mechanism, allowing the stator tension to be adjusted manually using screws.
This enables professional users to:
- Fine-tune pump pressure for specific materials
- Adjust performance based on application requirements
- Extend stator service life through controlled tension adjustment
Unlike maintenance-free systems, the D8-1.5 offers maximum flexibility for experienced operators.
Pressure Stability
Rubber deformation increases wear and reduces chamber pressure, which can lead to backflow inside the stator.
The optimized stator geometry and adjustable tension system help maintain stable pressure and reliable conveying performance even under demanding conditions.
Optimized Operating Temperature
Friction generates heat that negatively affects stator rubber. The carefully selected rubber compound and optimized heat dissipation help reduce operating temperature and minimize wear during continuous operation.
Uneven rubber wall thickness can prevent efficient heat dissipation — therefore, precision manufacturing is essential for durability and consistent performance.
