In the demanding world of fluid handling, the integrity of a pump is only as good as its internal components. At iCast Alloys LLP, we specialize in high-precision investment casting (lost-wax process) to produce pump components that offer superior hydraulic efficiency, structural integrity, and corrosion resistance.
By utilizing advanced metallurgical techniques and rigorous quality control, we provide global pump manufacturers with the reliable parts they need for oil and gas, chemical processing, water treatment, and power generation.
Investment casting is the preferred manufacturing method for complex pump geometries because it offers:
Near-Net Shape Accuracy: Minimizes the need for expensive secondary machining.
Smooth Surface Finish: Essential for reducing friction losses and improving the Flow Coefficient ($C_v$).
Design Freedom: Allows for intricate internal vanes and cooling passages that are impossible to achieve with traditional sand casting.
The impeller is the most critical component of any centrifugal pump. At iCast Alloys LLP, we provide tailored casting solutions for various impeller designs to suit specific industrial applications:
Designed with vanes attached only to the central hub, open impellers are ideal for pumps handling solids, slurries, and stringy materials.
Our Advantage: We cast open impellers with high structural wall thickness to withstand the abrasive nature of suspended solids, ensuring a longer service life in harsh environments.
Featuring shrouds on both sides of the vanes, closed impellers are the standard for high-efficiency clear liquid transport.
Our Advantage: The investment casting process excels here by creating smooth, precise internal channels. This reduces "skin friction" and ensures the pump maintains peak performance with minimal energy consumption.
iCast Alloys LLP works with a diverse range of alloys specifically selected for pump longevity:
Stainless Steel (304/316/316L): For general corrosion resistance.
Duplex & Super Duplex Steel: For high-pressure desalination and offshore applications.
Nickel-Based Superalloys: For handling aggressive acids and high-temperature fluids.
Carbon Steels: For cost-effective, high-strength structural pump housings.
Hydraulic Precision: Our castings ensure that the vane profiles match your CAD designs perfectly, preventing cavitation and turbulence.
Dynamic Balance Support: We produce castings with uniform density, making the final dynamic balancing process faster and more effective.
Non-Destructive Testing (NDT): Every pump component undergoes rigorous testing—including X-ray, Dye Penetrant (DP), and Hydro-testing—to ensure zero porosity and leak-proof performance.
Whether you are designing a vertical turbine pump or a standard end-suction centrifugal pump, iCast Alloys LLP is your partner for excellence in investment casting.
