Investment Casting Supplier for Pump Components
Neocast Alloys is your dedicated investment casting supplier for pump components. Near-net shape manufacturing with ±0.1mm accuracy, 50+ alloy grades, and fully machined, balanced parts for global OEM assembly lines.
Complete Pump Casting Range
As a comprehensive pump parts casting manufacturer, we investment cast the full range of rotating and stationary pump components.

The Investment Casting Advantage for Pumps
Pump OEMs choosing an investment casting supplier for pump components gain a decisive engineering advantage. The near-net shape process delivers smooth internal hydraulic passages that dramatically improve pump efficiency compared to rough sand castings.
We cast precision impellers with complex closed-vane geometries using soluble wax cores, produce pressure-tight casings, and manufacture alloy steel pump components in abrasion-resistant grades that would be prohibitively expensive to machine from billet.
Our ISO certified foundry provides a complete end-to-end supply chain: from custom alloy casting to CNC machining and dynamic balancing. Whether you need chemical process pumps or power plant pump parts, we deliver.
Frequently Asked Questions
Q.Why use investment casting for pump components?
Investment casting produces pump parts with smooth internal flow paths (Ra 3.2-6.3), tight dimensional tolerances (±0.1mm), and complex geometries impossible with sand casting. This directly improves pump efficiency and reduces costly machining.
Q.Can you cast closed impellers with internal vanes?
Yes. Using soluble wax and ceramic core technology, we cast fully enclosed impellers with complex overlapping vane geometries. These are impossible to machine conventionally and very difficult to produce via traditional sand casting.
Q.What alloys do you cast for pump components?
We cast 50+ alloy grades including CF8M (316), CD4MCU (Duplex), CA15 (Martensitic), WCB (Carbon Steel), high-chrome abrasion-resistant alloys, and nickel-based superalloys for extreme temperature and corrosion applications.
Q.Do you supply dynamically balanced, CNC-finished pump parts?
Absolutely. Our facility includes in-house CNC turning, milling, and dynamic balancing equipment. Every rotating component ships balanced and ready for direct OEM assembly, eliminating the need for secondary processing.
