Investment Cast Impellers

One of the biggest differences between the Ameriflo product line and all others is the excrutiating attention to detail that they make as a primary focus.  The heart of the pump, the impellers, determine overall performance and slope of the performance curve.  Ameriflo is the ONLY pump manufacturer that standardizes on investment cast impellers for standard construction in all manufactured fire protection product lines.  These impellers have very smooth fluid passageways which have a direct effect of increased  efficiency which can be seen on all published performance curves.

Ameriflo uses very complex Computational Fluid Dynamics (CFD) software to engineer the maximum efficiency and hydraulic performance from every impeller that they manufacture.  Solid Works software allows for the most efficient designing process currently available today.  End suction (ES), vertical inline (VI), split case (SC) and vertical turbine (VT) product lines use these impellers as standard construction.  The advantages of this engineering design and casting process are visible when you look at the performance curves offered by Ameriflo.  Ameriflo leverages technology not available in the past to design and develop the most advanced product lines available in the market today.

This casting process requires more expensive patterns, coreboxes and tooling but the advantages in the manufacturing process far outweigh the cost.  These impellers are cast to nearly finished dimensions with minimal matching and balancing required prior to assembly.  The standard material that Ameriflo uses is
304 stainless steel, a significant upgrade over bronze.  In applications where high levels of chlorine are present in the pumped fluid, highly zincified bronze impellers can be chemically attacked weakening there construction and minimizing overall life.  De-zincification is not an issue with 304 stainless steel impellers.

Other major components on the rotor group are also constructed out of 304 stainless steel material including the shaft sleeves, lantern rings and packing gland assemblies.  These materials ensure that your highly engineered piece of equipment will last decades in service and always perform as was originally intended.
