PFT Rotor Stator Twister D6-3 Set

Maintenance-Free D6-3 Screw Pump – Pressure-Stable & Ready to Use

Made in Germany

The PFT Twister D6-3 Rotor Stator Set is a high-quality screw pump designed for professional plastering and mortar applications. The set combines the D6-3 rotor with the maintenance-free PFT Twister stator to provide reliable material delivery, stable pumping pressure, and long service life.

The Twister stator features a maintenance-free, ready-to-use design with pre-set tension. No additional adjustment of the stator is required before operation – install the rotor stator set and the pump is ready for use.

With a pump size of 89 × 270 mm, a flow rate of 20 l/min at 400 RPM and 10 l/min at 200 RPM, the D6-3 Twister is designed for professional processing of plaster, mortar, and other compatible materials with a maximum grain size of 3 mm.

Key Advantages

• Complete D6-3 rotor stator set
• Made in Germany
• Maintenance-free PFT Twister stator
• Pre-set tension – no stator adjustment required
• Ready to use after installation
• Designed for low operating temperature
• High pressure stability
• Uniform stator wall thickness
• Durable rotor made from high-alloy tool steel
• Designed for professional and continuous construction-site use

Maintenance-Free Twister Stator

Unlike adjustable stators, the D6-3 Twister stator does not require tension adjustment.

The stator is manufactured with pre-set tension, providing the correct rotor-stator fit from the beginning. This simplifies installation and eliminates the need to regularly adjust the stator during operation.

The result is a straightforward ready-to-use screw pump system for professional plastering equipment.

Low Operating Temperature

Heat is an important factor in rotor stator wear. Friction between the rotor and rubber stator generates heat during operation, which can accelerate rubber deterioration.

The Twister stator uses an optimized rubber compound and uniform wall thickness designed to improve heat dissipation and keep operating temperatures low.

Reduced thermal stress helps limit wear and supports a longer stator service life.

Pressure-Stable Pumping Performance

The consistent rubber wall thickness of the Twister stator helps distribute mechanical stress evenly throughout the pump.

This supports:

• Stable chamber pressure
• Consistent material delivery
• Reduced backflow
• Reliable pumping performance
• Uniform operation under changing working conditions

The result is a rotor stator pump designed to maintain consistent performance during professional plastering and mortar applications.

High-Alloy Tool Steel Rotor

The matching D6-3 rotor is manufactured from high-alloy tool steel for high wear resistance and durability.

The rotor is designed for continuous interaction with the Twister stator and forms a precisely matched rotor-stator combination for demanding professional applications.

Applications

The PFT Twister D6-3 is suitable for compatible materials including:

• Gypsum plaster
• Gypsum-lime plaster
• Lightweight plaster
• Lime-cement render with grain sizes below 3 mm
• Adhesive mortar
• Reinforcing mortar
• Frame grouting mortar
• Mineral finishing coats
• Pasty finishing coats
• Dry loam plaster
• Fire protection mortar
• Concrete repair mortar

Material suitability always depends on the formulation and the specifications of the machine and material manufacturer.
