Optimum Product Conveyance

Large rectangular hopper, trumpet-shaped extrusion chamber, and horizontal screw feeder ensure efficient material transfer into the rotor-stator cavity.

Flexible Drive Configuration

Available in two variants: direct-flanged drive system (compact block design) or traditional bearing housing with free bare shaft for plug-in versatility.

Adaptable Intake Design

Rectangular hopper length adjustable to align with upstream components, ensuring seamless integration into existing systems.

Robust & Corrosion-Resistant

Engineered for abrasive and corrosive media; coupling rod with feeding blades forces materials into sealed conveying chambers.

Modular Scalability

Variable modular system enables tailored solutions for cutting, mixing, or high-precision conveyance.

Easy Maintenance

Large inspection openings and quick-access designs minimize downtime, supported by modular components for swift replacements.
