Dongguan HydroBlue Co., Ltd. supplies replacement impellers engineered for FLYGT submersible sewage pumps, covering the full range of impeller types including open, semi-open, closed, and vortex designs. Our team of eight engineers specialises in pump hydraulics, casting metallurgy, and precision machining, with research collaborations at Jiangsu University, Chinese Academy of Sciences, and Guangdong University of Technology. Beyond impellers, we supply complete pump spares, mechanical seal assemblies, motor control enclosures, and offer overseas field engineering support including 3D scanning of worn parts.
Send us your pump model and impeller specifications for a material recommendation and quotation.
Selecting the correct impeller type is the first step in ensuring pump performance and service life. FLYGT submersible pumps use several impeller designs depending on the application:
|
Impeller Type |
Solids Handling |
Efficiency |
Typical FLYGT Application |
|---|---|---|---|
|
Closed (shrouded) |
Small solids only (< 50 mm) |
Highest |
Clean water, drainage, high-head pumping |
|
Semi-open |
Moderate solids (50–75 mm) |
Medium |
Municipal sewage, fibrous media |
|
Open (non-clog) |
Large solids (> 75 mm) |
Medium |
Raw sewage, sludge, heavy debris |
|
Channel / vortex |
Very large or stringy solids |
Lower |
Wet-well solids handling, food processing waste |
The material choice directly affects impeller life in your specific media. We offer the following standard grades:

Every impeller we supply is produced under a documented quality plan covering the following stages:
Impeller wear is progressive and does not always cause immediate pump failure, but it reduces efficiency and increases energy consumption over time. The following indicators suggest replacement is needed:
Q1: What material do you recommend for standard municipal sewage?
HT250 cast iron is the most cost-effective choice for general sewage. For pumps handling abrasive sand or grit, upgrade to hi-chrome iron (500+ HB) which delivers 3–5 times longer wear life.
Q2: Can you match an existing impeller without drawings?
Yes. We reverse-engineer from a worn sample or high-quality photographs using FARO 3D laser scanning, and produce a CAD model for your approval before manufacturing.
Q3: Do you supply balanced impellers as standard?
Static balancing is standard on all impellers. Dynamic balancing (ISO 1940-1 G6.3 or G2.5) is available on request for high-speed pumps or critical installations.
Q4: What is the lead time for a duplex stainless steel impeller?
Duplex 2205 impellers require dedicated casting and heat treatment. Typical lead time is 45–60 days from deposit. Express service available with priority scheduling.
Q5: What warranty applies?
12 months from commissioning or 18 months from shipment. Covers material defects, dimensional non-conformance, and casting quality. Wear from abrasive media is application-dependent.
