Iron and Resin Sand Cast Chemical Pump Body Custom Casting Services Product

Our specialized iron and resin sand casting services deliver precision-engineered chemical pump bodies designed for demanding industrial applications. Utilizing advanced resin sand molding techniques combined with high-quality iron alloys, we produce pump bodies that offer exceptional corrosion resistance, mechanical strength, and long-term reliability in aggressive chemical environments.

Material Excellence
We employ premium iron alloys specifically formulated for chemical applications:

• Gray Iron (GG25/GG30): Excellent vibration damping characteristics with tensile strength of 250-300 MPa

• Ductile Iron (GGG40/GGG50): Enhanced impact resistance and pressure tightness through spherical graphite structure

• Ni-Resist Iron: Superior corrosion resistance for acidic and alkaline environments

• Special Alloy Irons: Chromium and nickel-alloyed variants for extreme chemical exposure
