Description

The pump impeller is the rotating component in the pump that directly transfers the energy from the motor into the fluid being pumped. Pump impellers are classified as one of three types: Open impeller, semi-open impeller, or closed impeller. Their classification is based on whether they have a protective shroud or not.

Impellers are casted in a variety of materials, including stainless steel, cast iron, bronze, aluminum, austenitic stainless steel, titanium, etc. When you choose the suitable material for pump impeller, you should think about the following several factors, strength, fluid compatibility, abrasion resistance, environmental conditions, type of liquid being pumped, casting and machining properties, etc.

Baoding Guokun can offer you the most suitable material as per your pump’s requirements. And with 25 years casting experience, we can produce the custom pump impellers with the suitable cast metal and casting process. The most common material for industrial pump impeller is 300 series stainless steel, for example, SAE 304 stainless steel, SAE 316 stainless steel, ASTM A351 CF8, ASTM A351 CF8M, etc

Product name Material Casting process
Pump impeller 300 series Stainless steel, 400 series stainless steel, low-carbon steel, alloy steel, mild steel, cast steel Investment casting ( lost wax casting)
Cast iron, ductile iron, grey iron Sand casting, lost foam casting
Bronze, Nickel-aluminum bronze, brass, aluminum, etc. Sand casting or gravity casting for aluminum pump impeller

Casting process of cast steel impeller

Investment casting is an industrial metal casting process based on lost-wax precision casting, generally used for producing complex-shaped metal components that require tighter tolerances, thinner walls and better surface finish than other sand cast parts. Baoding Guokun can produce various investment casting parts in low-carbon steel, mild steel, alloy steel, stainless steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.

Investment Casting Process Steps

The process of Baoding Guokun Investment casting involves several steps after producing a professional tool or mold in high-grade aluminum alloy, including:

No. Steps Details
1 Patterns Makings Hot wax is poured into the mold patten and allowed to harden, and then adding sprues to the wax model to create a tree-like structure.
2 Shell Building Coating the wax pattern with a layer of fire-resistant paint, and then to be sprinkled with sand, so after a period of hardening, the surface will form a layer of fire-resistant thin shell.
3 Dewaxing Removing the wax, the shell is placed into an oven, melting the wax so that it can run out of the shell.
4 Pouring Pouring the molten stainless steel into the shell, and waiting for solidification under room temperature.
5 Post treatment After cooling, knock the shell and cut the sprue gate by grinding machinery to achieve net shape impeller castings. Then shot blasting to move mill scales to assure the smooth casting surface.
6 Machining CNC Machining
