Double Suction (First Stage) Impeller features large passageways and produces balanced hydraulic thrust for a stable performance curve with low shut-off pressure.  The double-suction design on multistage pumps permits higher head and orating speed than vertical turbine models while maintaining excellent suction attributes.

Heavy Walled, Twin Volute Casing with robust transition diffuser moves liquid from casing to column through large waterways at low liquid velocity, minimizing corrosion, erosion and radial loads on bearings.

Suction Bells efficiently direct liquid into the impeller inlets with minimum resistance.

Bottom Liquid End Bearing is sealed for life with grease.

Optional Impeller Wear Rings enable restoration of original clearances for increased efficiency.
