By Structure / Design Type
We manufacture impellers in a full range of structures to suit different fluids, operating conditions, and efficiency goals.
Open Impeller
Blades are exposed on both sides, making it easy to clean and great for liquids with small amounts of debris.
Semi‑Open Impeller
One side has a cover for extra support, the other is open. Good balance between handling solids and maintaining efficiency.
Закрытое рабочее колесо
Blades are enclosed between two plates. Delivers higher efficiency and better pressure for clean liquids.
Channel Impeller
One or more flow channels guide the fluid through. Handles solids and fibers without clogging.
Screw Impeller
Spiral-shaped blades move fluid smoothly, perfect for thick or delicate materials.
Vortex Impeller
Recessed in the casing, creating a swirling flow. Reduces wear and helps avoid blockage.
По применению
We make impellers and blades for a wide range of uses, from everyday pumps to high-performance turbines.
Лопасти турбины
High-temperature and fatigue-resistant, built for energy and power generation turbine wheels.
Лопатки компрессора
Optimized for aerodynamic efficiency in compressors and HVAC systems.
Mixer & Agitator Blades
Designed for food, chemical, and pharma processing with fluid compatibility in mind.
Лопасти вентилятора
Lightweight and durable for industrial blowers and ventilation systems.
Centrifugal Pump Impellers
The most common type in industrial pumps, smooth, efficient for liquid transfer.
By Flow Direction
Whether your system requires which flow direction, we have the engineering expertise to deliver the right solution.
Radial Flow Impeller
Moves fluid perpendicular to the shaft. Best for high-pressure, low-flow jobs.
Axial Flow Impeller
Moves fluid parallel to the shaft. Ideal for high-flow, low-head systems like mixers or fans.
Mixed Flow (Diagonal) Impeller
Combines radial and axial features. Balances flow rate and pressure, common in wastewater and chemical pumps.
По материалу
We cast in a wide selection of high-performance alloys to meet demanding operational and compliance requirements.
Нержавеющая сталь
Corrosion-resistant and easy to clean. It’s a solid all-round choice.
Алюминиевые сплавы
Lightweight and rust-free, making it great for fans and low-temperature systems.
Bronze & Brass
Excellent wear and seawater resistance. Commonly seen in marine impellers.
Суперсплавы на основе никеля
Withstands extreme heat and stress, perfect for turbines and high-temp compressors.

Часто задаваемые вопросы
We work with stainless steel, carbon steel, aluminum alloys, and nickel-based superalloys like Inconel, covering most industrial needs.
We specialize in OEM and custom designs. Send us your drawings or samples, and we can manufacture to your exact specifications.
For most new designs, a minimum order is required due to mold tooling costs — especially for complex impellers. The specific MOQ needs to be negotiated based on the project.
However, we can produce smaller batches if you’re willing to cover tooling and higher per-unit pricing.
Yes. Investment casting allows us to achieve tight tolerances, and we can also provide CNC machining for critical dimensions.
Standard lead time is 4–6 weeks depending on complexity and order size. Rush orders can be arranged when possible.
We offer polishing, passivation, coating, and other surface treatments to improve performance and durability.
Yes. We regularly export to most countries on earth, including North America, Europe, and Asia, with secure packaging and reliable logistics.
