Overview

• Definition of the intake flow side (downstream flow from impeller)
• Two-part radial diffuser between impeller and volute
• Design specification to PFLEIDERER (constant swirl), STEPANOFF (constant speed) or own radii/surface area progression
• Design of the volute tongue and tongue correction
• Various cross-section forms: rectangle, trapezoidal, symmetrical/asymmetrical circle, free-form (Bezier)
• Tangential or radial diffuser with round or rectangular end cross-section
• 3D representation
