What Is Impeller Casting?
An impeller casting is a precision metal component used in pumps to transfer energy from the motor to the fluid. Through rotation, the impeller increases fluid velocity and pressure, making it a critical part of centrifugal pumps, water pumps, chemical pumps, and industrial fluid systems.
Compared with forged or machined impellers, casting allows:
- More complex blade geometry
- Better material utilization
- Lower cost for medium and large batches
- Wider material selection
Impeller casting is widely used in industries where flow efficiency, wear resistance, and corrosion resistance are essential.
The Function of the Impeller:The main function of the impeller is to convert mechanical energy into fluid energy. For example, in a pump, the rotation of the impeller can generate centrifugal force. It sucks the fluid into the pump and accelerates it outward. Thus increasing the fluid’s speed and pressure.
The types of Impeller Casting
Different types of impeller has different features and applications. For more info, kindly check the article:
Impeller Casting Material Types
We understand that different applications need specific material properties. So, we offer a variety of materials for impeller castings.The right impeller material is crucial for the performance and longevity of the pump system.

- bronze impeller casting, brass impeller casting
Titanium Alloy Impeller Casting
- For high-temperature applications.
- Such as power generation turbines and aero engines.
Aluminum Impeller Casting
- light weight, high strength and good corrosion resistance.
- Reduce the load of equipment.
- Used in aerospace and automotive industries.
Marine Industry Case:A shipbuilding company’s seawater cooling system required an impeller. The impeller was made of duplex stainless steel. It can withstand the harsh marine environment. The corrosion resistance and erosion resistance of the impeller ensured long-term and reliable operation, reduced the need for frequent replacements, and minimized the ship’s downtime. The shipbuilding company was deeply impressed by the performance of the impeller and has continued to purchase impellers from us for their new ship projects ever since.
Impeller Casting Processes We Use
Choosing the right impeller casting process is critical for performance, accuracy, and cost. JC Casting provides multiple options to ensure your impeller castings meet the highest standards.

CNC Machining & Balancing
After casting, impellers can be fully machined and dynamically balanced to ensure:
- Stable rotation
- Reduced vibration
- Longer bearing life
Size Range
Our manufacturing capabilities enable us to produce impellers within a wide range of sizes. We can produce small impellers with a diameter as small as a few centimeters. They are suitable for medical equipment, small pumps, and precision machinery. We also have the expertise and equipment to handle large impellers with a diameter of more than several meters. These impellers are usually used in power plants, large industrial pumps, and marine applications.
Small Precision Case
A microfluidic pump of a laboratory equipment supplier required an impeller with a diameter of only 3 centimeters. Using our precision machining and investment casting technologies, we were able to produce an impeller with extremely small tolerances. The impeller had precise dimensions and a smooth surface, enabling it to handle fluids efficiently at the micron scale and meet the high standards of the laboratory equipment.
Large Industrial Example
A large power plant required an impeller with a diameter of 3.5 meters for their water treatment equipment.
