Double Suction Impeller and Heavy-Duty Double Volute Casing inherently result in optimum axial and radial thrust balance over the full operating range.

Hydraulically Balanced Double Suction Impeller reduces NPSH requirements and ensures smooth, efficient operation over a wide range of conditions.

Dynamically Balanced Impellers to ISO 1940 tolerances.

Independent Cast Seal Chamber housing for packing or mechanical seal.

Shaft conservatively designed to minimize deflection and reduce maintenance costs caused by wear.
