Core Advantages
Lost Wax Precision Casting Craftsmanship
Adopt full lost wax investment casting process, eliminating rough machining defects. Complex curved blade profiles, integrated hub and vane structures are formed in one casting, with minimal post-processing required. The intricate radial fan blade design you see in the picture ensures stable hydraulic performance and balanced rotation during pump operation.
Premium Stainless Steel Material Options
Available in 304, 316, CF8M, CD4MCU and other stainless-steel grades. Excellent resistance to water, weak acid, alkali and salt corrosion, ideal for water pumps, chemical transfer pumps, sewage pumps and food-grade fluid processing pumps. High tensile strength and wear resistance extend service life under continuous high-speed rotation.
Stainless steel has many properties, including corrosion resistance, durability, temperature resistance, recyclability, maintenance, modern appearance, high tensile strength, good ductility and high hardness. The stainless steel can be used in many different industries, such as automotive, aircraft, construction, marine, medical, food, etc.
The common stainless steel grades
| stainless steel alloys | |||||||
| Grades | Chemical Composition | Mechanical Properties | |||||
| C | Cr | Ni | Mo | Tensile Strength MPa | Yield strength Mpa | Elongation % | |
| 304 | ≤0.08 | 18 ~ 20 | 8 ~ 11 | – | ≥520 | ≥205 | ≥45 |
| 304L | ≤0.03 | 18 ~ 20 | 8 ~ 12 | – | ≥480 | ≥175 | ≥45 |
| 316 | ≤0.08 | 16 ~ 18 | 10 ~ 14 | 2 ~ 3 | ≥520 | ≥205 | ≥45 |
| 316L | ≤0.03 | 16 ~ 18 | 10 ~ 14 | 2 ~ 3 | ≥480 | ≥175 | ≥45 |
| 410 | ≤0.12 | 11.5 ~ 13.5 | ≤0.75 | – | ≥440 | ≥205 | ≥20 |
| 430 | ≤0.12 | 16 ~ 18 | ≤0.75 | – | ≥450 | ≥205 | ≥22 |
The most common stainless steel alloy is austenitic stainless steel, particularly Grade 304 and Grade 316, which is a mixture primarily composed of Cr and Ni, offering good corrosion resistance and excellent formability, making them widely used in various applications.
Strict Dimensional & Surface Control
Precision casting tolerances meet ISO casting standards. Smooth as-cast surfaces reduce flow resistance inside pumps, improving pump efficiency and lowering energy consumption. Customizable hub bore sizes, blade quantities and outer diameters to match your pump motor assemblies perfectly.
Wide Industrial Application Scenarios
These stainless-steel cast impellers are widely used in clean water pumps, industrial chemical pumps, wastewater treatment pumps, agricultural irrigation pumps, and food & beverage processing pump systems. The integrated monoblock casting structure guarantees structural rigidity, avoiding blade deformation or fracture under high pressure fluid circulation.
