Three- or Four-Vane Axial Flow Propeller is hydraulically balanced via pressure equalizing balance holes and a top propeller hub wear ring to reduced axial down thrust.
Outer Flanged Columns are bolted together with through bolts for ease in assembly. Alignment is maintained via centering fits on all parts
Flared Suction Bell provides a smooth waterway entrance to the impeller and has integral splitters to reduce inlet swirl and entrance losses
Stator Case With Integral Diffuser Vanes may be either a single-piece casting or a fabrication.
Discharge Elbow may be located above or below ground and at any outlet orientation.
Seal Chamber accepts packing or mechanical seal to suit service requirements.
• Flows to 181700 m3/h (800 000 gpm)
• Heads to 11 m (35 ft)
• Speeds to 1770 rpm
• Sizes 200 mm (8 in) to 3.1 m (123 in)
• Settings to 8 m (25 ft)
The VAF is a vertical high efficiency, axial flow impeller pump together. we have a complete range of this type of pumps which are suited for applications that require large quantities of flow with low head.
