SIMSITE® NON-CLOGGING IMPELLERS

Simsite® Structural Composite Non-Clogging Impellers are Superior to Metallic Impellers, because they are light weight, easy to install, and engineered to last as well as pass more particulate, eliminate corrosion, electrolysis, and cavitation problems that are inherent in metallic impellers!  Simsite® Composite Non-Clogging Impellers have excellent lubricity with a low coefficient of friction, which prevents material sticking and clogging. SIMS PUMP is able to offer such superior impellers because 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.

Simsite® Non-Clogging Impellers enable more particulates to pass through the vanes and their design prevents clogging of the particulate in the fluid being pumped. Fortunately, Simsite® Impellers are engineered to reduce, or eliminate the effects of clogging, corrosion, erosion and 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 a 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 lightweight, reducing start-up load and shaft deflection. The result is an increase in the lifetime of Bearings, Seals, Rings, and Sleeves!

SIMSITE® Products are patented and completely different from any other Impellers & Casing rings in the marketplace because they are fully machined from solid blocks of SIMSITE®,  which never corrodes in seawater, brackishwater, river water, chlorinated water, sewage, waste water, and many other chemicals.

Our SIMSITE® Impellers and Casing Rings are truly unique because they are completely (100%) machined on the inside as well as the outside. The 5-axis to 8-axis precision machining makes our SIMSITE® impellers perfectly balanced both mechanically, and hydraulically – if an impeller is machined from one center position, there is NO Imbalance!

Furthermore, because our impellers do not corrode in seawater, brackish water, river water, wastewater, and many chemicals, they do not go into an imbalance and therefore they do not experience performance degradation like metallic products.

SIMSITE® Impellers and Rings are excellent for new, upgrade, repair, or retrofit applications.  They are lightweight and virtually indestructible. Wear of other pump parts including the pump casing are greatly reduced because of the SIMSITE® Impeller’s perfect balance, lightweight, self-lubricating, sealing, and corrosion, erosion, & cavitation resistance. This means far less expense for the replacement of parts, downtime, and years of trouble-free performance.

Simsite® Impellers and Casing Rings are designed for Superior Hydraulic Performance because the Impellers are computer engineered, designed, and precision machined. The impeller vane geometry can be engineered to maximize effciency and performance. Problems such as recirculation, radial thrust, and cavitation can be minimized, or eliminated by upgrading to Simsite®  Impellers   &  Casing Rings.   Impeller vane shapes can easily be modified to provide the best vane shape for specific applications and performance requests.

  1. Simsite® Impellers & Casing Rings are superior to all metallic Products in Salt Water, Brackish Water, River Water, Waste Water, Chlorinated Water, and many Chemical services, because they do not corrode and because they are machined as opposed to being cast, or molded.
  2. Simsite® Impellers & Casing Rings NEVER CORRODE in Seawater,   Sewage,   Waste Water,    Brackish Water, or Chlorinated Water! One of the most important advantages of Simsite® structural composite products in comparison to metal is its ability in resistance to both corrosion and erosion in corrosive environments!

Lower Costs, Increased Performance Sims Simsite® impellers, and rings are excellent for new, repair, or retrofit applications. They are lightweight and virtually indestructible. Wear of other pump parts including the pump casing is greatly reduced because of the Simsite® impeller’s perfect balance, lightweight, self-lubricating, sealing, and corrosion, erosion, and cavitation resistance.  This means far less expense for the replacement of parts, downtime, and years of trouble-free performance.

DESIGNED FOR SUPERIOR HYDRAULIC PERFORMANCE

Because Simsite® impellers are computer engineered, designed, and precision machined, the impeller vane geometry can be engineered to maximize efficiency and performance. Problems such as re-circulation, radial thrust, and cavitation can be minimized, or eliminated by upgrading to Simsite® impellers and rings. Impeller vane shapes can easily be modified to provide the best vane shape for specific applications and performance requests.

OPTIMIZATION

It is all too common a problem — you purchased a pump for one specific performance and when you put the pump into service in your plant or ship, the pump operates at another point completely different from the original design point (BEP or best efficiency point) of the pump because of your system requirements. In addition to being very inefficient, when you operate the pump away from the original design point or BEP, it causes a multitude of problems. These problems include excessive noise and vibration, shaft oscillation, cavitation, premature wear, and failure of the mechanical seals, bearings, rings, sleeves, and impellers. In extreme cases, the shaft will break.

SIMSITE® IMPELLERS — PERFECT FOR RETROFIT & REPLACEMENT APPLICATIONS

  1. LIGHTWEIGHT — The exceptional high strength-to-weight ratio of Simsite® permits a much lighter weight This means a substantial reduction in start-up load, longer bearing and mechanical seal life, and less shaft deflection.
  2. REDUCES NOISE AND VIBRATION — Because of the high efficiency design of the Simsite® Impeller, its light weight, its noise-absorbing characteristics, and its precision machined design, noise and vibration are reduced in the pump
  3. ELIMINATES CORROSION, AND BALANCE PROBLEMS — Simsite® Impellers are an ideal replacement for metallic impellers, especially in corrosive pumping applications. Because Simsite® is an inert product, electrolysis within the pump is reduced or When Metallic Impellers corrode, they become unbalanced, causing premature wear on all other rotating parts. By replacing worn out parts with Simsite®, the pump lasts longer and costs are reduced!
