Pump manufacturers have a narrower problem than most industrial buyers when it comes to sourcing forged components — pump shafts, impeller hubs, and casing parts need to hold concentricity and fit tolerances exactly, because even a small deviation shows up as vibration or premature bearing wear once the pump is running. Sharma Technocast forges these parts using whichever process actually suits the geometry — open die for larger shafts and structural components, closed die where a smaller part needs to be produced at volume, roll forging where a shaft needs to taper along its length. Material selection follows the same logic: carbon steel where it’s enough, alloy steel where the pump runs at higher pressure or temperature, stainless steel where corrosion resistance is non-negotiable. What actually finishes the job, though, is machining — a forged shaft or hub still needs to land on its final bearing fit and bore dimensions before it goes anywhere near assembly. That happens here too, alongside casting and fabrication for pump components that need a mix of processes rather than just forging.
