SIMSITE® Structural Composite Open Faced Pump Impellers are Superior to Metallic Impellers, because they are engineered to last as well as eliminate electrolysis, vortexing and cavitation problems that are inherent in metallic impellers! ImpellerStore is able to do this because our SIMSITE® Impellers are machined from solid blocks of SIMSITE® Structural Graphite Composite. SIMSITE® Impellers are machined on the outside as well as the inside on 5 to 8 axis machining centers.

Fortunately, SIMSITE® Impellers are engineered to reduce or eliminate the effects of cavitation. Because SIMSITE® Impellers are precision machined from solid blocks of the structural composite, the impeller vane geometry can be engineered utilizing CFD (Computerized Fluid Dynamics) techniques and programs to eliminate the vortexing and cavitation problems experienced by cast or molded metallic impellers.
SIMSITE® Engineered composite impellers & Casing Rings offer even greater savings, because they can be engineered to make the pump operating point the Best Efficiency Point (BEP) which significantly increases efficiency! (The farther away the pump operates from BEP, the lower the efficiency, and the higher the radial loading, movement and vibration.) The machined vane surfaces provide smoother surface finishes, which allows for a lower coefficient of friction with self-lubricating qualities. Machined Structural Composite Impellers & Rings are 5 to 6 times lighter than metallic impellers and run on tighter wear ring to casing ring clearances.
This provides reduction in mechanical losses as well as volumetric losses. Since machined composite impellers are perfectly balanced, both hydraulically and mechanically, and maintain this balance throughout the life of the pump, this reduces vibration, and allows the pump to operate more efficiently which reduces downtime and operational costs. Engineered structural composite products also prove light weight, reducing start-up load and shaft deflection. The result is an increase in the lifetime of Bearings, Seals, Rings and Sleeves!
