FLYGT High Performance Industrial Centrifugal Pump Impeller

Introducing the brand we created to provide professional overall technical solutions in fluid machinery and engineering. Industrial control and drive equipment, mechanical seals, overseas field engineering solutions, etc.

We have a series of professional technologies and product brands that can provide you with leading technical services, sales support and product supporting solutions - empowering you with pumps, frequency converters, servo drives, PLC servo drives HMI, industrial control cabinets, motors, Reduced motors, mechanical seals and systems, couplings, gearboxes and engineering solutions (overseas on-site service of 3D scanning reverse molding of pump replacement parts to your satisfaction, and on-site equipment debugging services by overseas dispatched engineers).

• Reverse-Engineered Precision — FARO 3D laser scanning captures OEM hydraulic geometry with ±0.05mm accuracy; no original drawings required
• Material Flexibility — Duplex SS, 316L, alloy steel options to match your media corrosivity and abrasiveness
• CNC-Machined Interchangeability — Machined to tolerances that guarantee direct fit with FLYGT original pump assemblies
• Full Traceability — Material certificates, inspection reports, and NDT documentation provided with every shipment
• Dynamic Balancing — Every impeller is statically and dynamically balanced to ISO 1940-1 Grade G6.3 to minimize vibration
• Proven Track Record — Supplied to municipal wastewater plants and industrial facilities across 15+ countries

We operate both investment casting and sand casting lines to accommodate different impeller sizes, geometries, and material requirements:

All castings are heat-treated to relieve stress and achieve specified mechanical properties. Method of casting is selected based on impeller size, material, and quantity — our engineering team will recommend the optimal process for your order.

Precision machining is performed on 3-axis and 4-axis CNC centers to ensure hydraulic profile accuracy and mounting dimensional compliance:

• CNC Machining — Primary machining of hydraulic passages, hub, and shaft bore
• Auto Lathe Machining — High-efficiency rough machining of rotational surfaces
• Wire Cutting (EDM) — Precision cutting of keyways and complex internal profiles
• Grinding — Shaft bore and seal fit surfaces to <Ra 1.6µm finish
• Milling & Drilling — Mounting holes, set-screw holes, and secondary features
• Dynamic Balancing — Two-plane balancing to ISO 1940-1 Grade G6.3

All machining is performed to CAD model tolerances with in-process inspection at key stages.

Surface treatment options are selected based on material and operating environment:

• Blacking (Oxide Coating) — Cast iron and steel; mild corrosion protection
• Polishing — Stainless steel; improves surface finish and cleanability
• Anodizing — Aluminum components; enhanced corrosion resistance
• Chrome Plating — Wear surfaces; increased hardness and abrasion resistance
• Zinc Plating — Carbon steel fasteners and small parts; sacrificial corrosion protection
• Nickel Plating — Corrosion-resistant coating for aggressive chemical environments
• Custom Coating — Epoxy, PTFE, or ceramic coating available upon request (in cooperation with Chinese Academy of Sciences special coating technology)

Every impeller undergoes comprehensive quality inspection throughout the manufacturing process:

1. Material Certificate — Full traceability for all raw materials against ASTM, DIN, EN, ISO, TOCT standards
2. Hardness & Roughness Testing — Verifies material hardness and surface finish quality of hydraulic surfaces
3. Dimensional Inspection — 3D coordinate measuring against CAD model tolerances; shaft bore diameter, hub runout, blade profile
4. Non-Destructive Testing — PT (Penetrant), RT (Radiographic), UT (Ultrasonic), MT (Magnetic) for cast and machined components
5. Hydrostatic Pressure Testing — Pressurized leak test to confirm structural integrity before delivery
6. Static & Dynamic Balancing — Balancing test for rotating impeller components to minimize vibration at operating speed

Certifications: ISO9001:2015, ISO14001:2004, API Specification Q1.
