Hansheng Automation (Dongguan) Co., Ltd.

The impeller is a critical component of any centrifugal pump system, converting mechanical energy into fluid pressure and velocity. Hansheng Automation (Dongguan) Co., Ltd. combines precision casting with advanced multi-axis CNC machining to manufacture custom pump impellers tailored to your technical drawings.

By applying our expertise in precision machinery, we deliver impellers that help optimize fluid system efficiency, lower energy consumption, and extend the operating life of your pumps under demanding industrial conditions.

[Key Features & Capabilities]

Precision CNC Machining: Utilizing advanced machining centers, we can achieve tolerances down to ±0.002 mm and a surface roughness up to Ra 0.2. This smooth finish helps minimize friction loss within the flow channels.
Accurate Geometry Replication: Our 5-axis CNC equipment accurately reproduces complex blade curves and spatial surfaces according to your 2D or 3D engineering designs.
Strict Dynamic Balancing: Every impeller undergoes dynamic balancing testing to meet up to ISO G2.5 standards, helping reduce vibration and noise while protecting bearings and mechanical seals.
Quality Assurance & Material Traceability: We offer multiple casting processes (sand casting, investment casting, etc.) and support material certifications. Pre-furnace spectral analysis and third-party test reports are available upon request to ensure material compliance.
