Investment Casting for Valves, Pumps, and Process Equipment
Leak-Tight, Chemically Resistant Castings for Flow Control and Fluid Handling Applications
Investment casting ? also known as lost wax casting ? is the process of choice for valve bodies, pump housings, and flow-control parts where leak-tight accuracy and chemical resistance cannot be compromised.
Pahwa MetalTech supplies valve bodies, pump components, impellers, and fittings to chemical, petrochemical, and process industries where corrosion resistance and dimensional flow integrity are non-negotiable.
Stainless steel 316/316L, duplex grades, and Hastelloy alloys form our core process equipment portfolio ? chosen for resistance to aggressive chemicals, elevated operating temperatures, and erosive process media.
Investment Cast Parts for Flow Control and Fluid Handling Systems
Our castings are specified for globe valves, gate valves, check valves, centrifugal pump housings, and process manifolds. Every component is dimensionally verified to confirm seat integrity and leak-free assembly.
- Globe valve, gate valve, and check valve bodies
- Centrifugal and positive displacement pump housings
- Impellers and wear rings
- Process manifold blocks and fittings
- Pressure vessel and reactor components
- Pipe fittings and flanged connections
- Instrumentation housings for flow and pressure systems
If Your Process Fluid Won't Forgive, Your Casting Supplier Shouldn't Either
Pahwa MetalTech has built its process equipment programme around one principle: a rejected valve body costs more than the casting. We invest in getting alloy selection and tolerances right the first time.
Submit your valve or process component drawing. We'll review wall sections, passage geometry, and alloy compatibility ? and return a quote covering all casting and inspection requirements for your specification.
