Stainless Steel Casting

Typical products of stainless steel castings
Pump components: pump body, pump casing, impeller, pump cover, pump base
Valve castings: valve body, valve cover, valve disc, flange
Fluid accessories: pipe fittings, flanges, three-way joints, elbows
Mechanical structural components: supports, bases, non-standard parts, etc.

Stainless steel casting is the premier manufacturing process for high-performance pump components, widely used for pump housing, impeller, pump casing, pump cover, and pump base. Precision investment casting (lost wax casting) is the most adopted solution for centrifugal pumps, chemical pumps, sewage pumps, seawater pumps, and sanitary pumps.

Key Advantages

High Precision & Complex Geometry
Silica sol investment casting delivers tight tolerances (CT5-6) and smooth surface finish (Ra1.6-Ra3.2), ideal for intricate flow passages and thin-wall structures, greatly reducing machining work.
Premium Corrosion-Resistant Materials
Common grades include 304 (CF8), 316L (CF8M), and duplex stainless steel 2205/2507. They offer excellent resistance to corrosion, cavitation, and high temperature, suitable for seawater, chemical fluids, and harsh operating conditions.
Strong Structure & Long Service Life
Uniform internal structure, high mechanical strength, and reliable sealing lower leakage and wear, extending pump service life and reducing maintenance costs.
OEM & Custom Production
Custom casting services based on drawings or samples, supporting both small-batch precision parts and mass industrial production, compliant with ISO, ASTM, DIN, JIS standards.

Typical Applications

Water treatment, petrochemical, seawater desalination, food & beverage, pharmaceutical, power, metallurgy, and HVAC systems, providing durable, corrosion-resistant stainless steel castings for reliable pump performance.
