Pump Casting Manufacturer
Neocast Alloys is a premier pump casting manufacturer in India. Supplying flawlessly cast impellers, volutes, and casings that maximize hydraulic efficiency for the world's leading pump OEMs.
Complete Wet-End Kits
As an experienced pump casting manufacturer, we utilize soluble wax techniques to cast highly complex internal geometries that are impossible to achieve with traditional methods.
Optimized for Performance
Investment casting is the superior choice for high-performance industrial pumps where internal finish and chemical resistance are paramount.
Hydraulic Efficiency
Smooth internal cavities (Ra 3.2-6.3) drastically reduce friction and turbulence.
Dynamically Balanced
Impellers cast with exceptional symmetry, ready for high-RPM operation.
Corrosion Resistant
Casting in Duplex, Super Duplex, and Hastelloy for aggressive fluid handling.
Pressure Integrity
100% NDT inspection guarantees zero porosity in pressure-retaining casings.
Your Dedicated Pump Partner
Pump performance is entirely dependent on the quality of its castings. Imbalanced impellers cause vibration, and rough internal volutes cause friction. That is why tier-1 OEMs choose Neocast Alloys as their primary pump casting supplier.
We are a comprehensive pump parts casting manufacturer, managing the complete lifecycle. From 3D flow simulation and pattern design to pouring custom alloys and performing 100% NDT inspection, we guarantee zero-defect delivery.
Whether you need a heavy-duty pump housing for municipal water treatment or a super-duplex impeller for offshore oil extraction, our ISO certified foundry is equipped to meet your exacting standards.
Frequently Asked Questions
Q.What pump components do you manufacture?
As a specialized pump casting manufacturer, we produce entire wet-end kits, including closed impellers, open impellers, volute casings, diffusers, submersible bowls, and bearing housings.
Q.How does investment casting improve pump performance?
Investment casting produces a much smoother internal surface finish compared to sand casting. This smooth finish significantly reduces fluid friction and turbulence inside the volute and impeller, directly increasing the pump's hydraulic efficiency.
Q.What alloys do you use for chemical and seawater pumps?
For highly corrosive applications like chemical processing or seawater desalination, we cast pump parts in Duplex Stainless Steel (CD4MCU), Super Duplex (Zeron 100), and Nickel alloys like Hastelloy and Monel.
Q.Are your pump castings machined?
Yes. We operate an advanced in-house CNC machine shop, allowing us to supply pump castings that are fully machined, dynamically balanced, and ready for immediate assembly.
