D5-2.5 Rotor Stator Set

Maintenance-Free Screw Pump for Plaster & Mortar – 22 l/min

The D5-2.5 Rotor Stator Set is a professional progressive cavity pump designed for reliable performance in plastering, mortar, and material pumping applications.

The D5-2.5 features a maintenance-free stator with preset tension, allowing the pump to be installed and used without manual stator adjustment. This makes it a practical ready-to-use solution for professional construction equipment.

With a flow rate of 22 l/min at 400 RPM, a maximum grain size of 3 mm, and a 73 Shore stator, the D5-2.5 provides controlled material delivery for a wide range of compatible plaster and mortar applications.

The matching rotor is manufactured from high-alloy tool steel, while the maintenance-free stator is supplied in grey.

Maintenance-Free Design

The D5-2.5 stator is designed as a maintenance-free pump component with preset tension.

Unlike adjustable stators, no external or integrated clamp needs to be manually adjusted during normal operation.

This provides a straightforward pump setup:

• No manual tension adjustment
• Preset pump configuration
• Ready for use after installation
• Consistent setup without operator adjustment

For users looking for a simple and reliable D-series screw pump, the maintenance-free design makes the D5-2.5 particularly practical.

Benefits

22 l/min Material Output

The D5-2.5 provides:

• 22 l/min at 400 RPM
• 11 l/min at 200 RPM

This controlled material output makes the pump suitable for professional plaster, mortar, and similar material pumping applications.

Up to 3 mm Grain Size

The D5-2.5 is suitable for compatible pumpable materials with a maximum grain size of 3 mm.

73 Shore Stator

The matching stator uses a 73 Shore rubber compound and measures 89 mm in diameter and 270 mm in length.

High-Alloy Tool Steel Rotor

The D5-2.5 rotor is manufactured from high-alloy tool steel for professional use in progressive cavity pumping applications.

Preset Stator Tension

The stator tension is preset, eliminating the need for manual adjustment during normal operation.

This makes installation and operation particularly straightforward compared with adjustable stator systems.

Complete Rotor Stator Set

The D5-2.5 is supplied as a complete rotor and stator combination, providing the two primary pump components as a matched set.

Applications

The D5-2.5 is suitable for compatible:

• Plaster
• Render
