Investment Casting Stainless Steel Pump Bodies Introduction
As a leading investment casting foundry specializing in Investment Casting Stainless Steel Pump Bodies components, we manufacture high-precision pump bodies, pump casings, pump housings, and volute castings through the advanced lost wax casting process.
Our precision casting capabilities cover a comprehensive range of centrifugal pumps, single-suction pumps, multistage pumps, end-suction pumps, split-case pump assemblies, and vertical turbine pumps.
Serving as a trusted OEM pump parts supplier for manufacturers worldwide, Leesh deliver Investment Casting Stainless Steel Pump Bodies that meet demanding performance requirements across water treatment, chemical processing, oil and gas, marine engineering, desalination, food processing, and industrial fluid handling applications.
Leesh Investment Casting Stainless Steel Pump Bodies casings are produced in a wide variety of material grades — including 304 (CF8), 316 (CF8M), 304L (CF3), 316L (CF3M), CA15 410 martensitic, CA6NM, 17-4PH precipitation hardening, duplex 2205 (CD4MCu / 4A), super duplex 2507, and nickel-based alloys — for extreme corrosion resistance, high-temperature service, and abrasive wear environments.
The lost wax investment casting method enables us to produce complex pump component geometries that would be cost-prohibitive through conventional sand casting or machining from solid bar stock. Intricate internal flow passages, volute scrolls, cutwater profiles, wear ring seats, impeller chambers, stuffing box cavities, and integrated mounting flanges are cast directly to finished or near-finished dimensions, significantly reducing secondary CNC machining time and associated tooling costs. Leesh precision casting tolerances consistently achieve CT4 to CT6 per ISO 8062 / GB/T 6414, with as-cast surface roughness as low as Ra 3.2 μm (125 RMS).
