Customized Iron Gear Pump Parts OEM Lost Wax Foundry Type Gravity Casting Casting Services Product Category

In the fluid handling industry, customized iron gear pump parts represent critical components where precision engineering meets advanced foundry technology. Our specialized OEM lost wax investment casting and gravity casting services produce gear pump components that deliver exceptional performance, durability, and reliability in demanding pumping applications across multiple industries.

Advanced Iron Material Specifications

Our gear pump parts utilize premium gray iron and ductile iron formulations specifically engineered for fluid handling applications. Gray iron grades G2500-G3500 provide excellent vibration damping characteristics and natural lubricity from the graphite flake structure, with tensile strength reaching 35,000 psi . For applications requiring enhanced mechanical properties, we employ ductile iron grades 65-45-12 and 80-55-06, delivering tensile strength from 65,000 to 80,000 psi with elongation up to 12% for improved impact resistance . All materials undergo rigorous spectrographic analysis to ensure consistent chemical composition, with carbon content typically ranging from 3.2-3.6% and silicon content of 1.8-2.5% to optimize casting characteristics and mechanical performance.

Precision Manufacturing Processes

Our comprehensive foundry services integrate multiple advanced casting technologies:

Lost Wax Investment Casting
