Welcome to the forefront of pump technology at SIMS Pump Company, where innovation, performance, reliability, efficiency and longevity drive our every move. As a recognized leader in advanced Impeller & Pump Engineering Design for Centrifugal Pump technologies, SIMS PUMP is dedicated to engineering solutions that not only meet but exceed global standards of performance, reliability, longevity, efficiency and environmental responsibility.

SIMSITE® Structural Composite Impellers & Casing Rings NEVER CORRODE In Seawater:
SIMSITE® Impellers and Casing Rings NEVER CORRODE in Seawater Brine, Sewage, Chlorine, Scrubbers, or Waste Water!
Our flagship Simsite-impellers & Casing Rings, Manufactured from our patented SIMSITE® Structural Composite from advanced structural composites, offer . SIMSITE® Impellers & Rings are designed and engineered to meet the specific performance requirements of Customer’s needs.
By maximizing the impeller design, the operating point (OP) becomes the best efficiency point (BEP) making the pump much more efficient and eliminating high radial loading which reduces shaft deflection and eliminates cavitation problems! The reduction in shaft deflection combined with the light weight of the SIMSITE® Structural Composite (85% less weight than Bronze or Stainless Steel) enables the bearings, mechanical seals, sleeves, rings and motor to last much longer!
Uniquely, SIMSITE® Impellers & Casing do not corrode in Seawater and are not subject to erosion, cavitation, electrolysis, or performance deterioration like metallic impellers! The exceptional mechanical strength of SIMSITE® Impellers & Casing Rings enables them to outlast and outperform traditional metallic impellers and casing rings!
The advanced design of SIMSITE® Impellers & Casing Rings optimizes fluid dynamics, which reduces vibration, shaft deflection, and cavitation problems, and boosts overall pump efficiency, which is vital for sustaining the longevity, reliability and integrity of the pump and pumping system.
The precision design, machining and engineering of these components reduces noise, and vibration making SIMSITE® Impellers & Casing Rings suitable for many different pump applications. Additionally, their high mechanical strength and reliability ensures consistent performance across various fluids and pump applications, temperatures, and their lightweight reduces shaft deflection and reduces wear on the entire rotating element!
Key Benefits of Using SIMSITE® Impellers & Casing Rings :
• Operational Cost Reduction: The enhanced durability, longevity and efficiency of SIMSITE® Impellers & Casing Rings significantly reduce the need for frequent maintenance and replacement. This translates to lower operational costs and decreased downtime, providing substantial longterm savings.
• Increased System Lifespan: With their ability to maintain structural integrity under harsh corrosive conditions, SIMSITE® Impellers & Casing Rings extend the lifespan of the pump and the entire pumping system. This not only saves on capital expenditures but also ensures continuous performance without unexpected interruptions.
• Energy Efficiency : The improved hydrodynamic design of SIMSITE® Impellers and Casing
Rings reduces energy consumption by minimizing hydraulic losses. This improved efficiency is crucial for reducing the environmental impact of operations and for lowering energy costs, making it an ideal solution for Vessels and Corporations aiming to meet stringent energy regulations and sustainability goals.
Advanced Engineering Design : The ability to design, engineer, and machine each Simsite® Structural Composite Impeller & Casing Ring Set on 5 to 8 Axis machining centers to the Customers specific system requirements not only optimizes performance, reliability and longevity, but also offers the ability to address unique operational challenges. This unique approach enhances the overall pump system efficiency and adapts to changing operational needs without requiring complete system overhauls.
