Description

Premium Quality Stainless Steel Pump Impellers – Manufacturer & Exporter

Stainless Steel Fittings India is a leading manufacturer, supplier, and exporter of Stainless Steel Pump Impellers engineered for exceptional hydraulic performance, corrosion resistance, and durability. Our pump impellers are precision-cast and machined from high-grade stainless steel alloys to meet the rigorous demands of industrial, marine, chemical, and water treatment applications worldwide.

A pump impeller is the rotating component within a centrifugal pump that transfers energy from the motor to the fluid being pumped. Stainless steel impellers are the preferred choice where corrosion resistance, hygiene, and long service life are critical requirements. At Stainless Steel Fittings India, every impeller is manufactured to exact dimensional tolerances and undergoes stringent quality checks before dispatch.

Types of Stainless Steel Pump Impellers We Manufacture

We offer a comprehensive range of stainless steel pump impellers designed for different flow requirements and applications:

• Open Impellers – Suitable for handling liquids with suspended solids; easy to clean and inspect.
• Semi-Open Impellers – Ideal for moderately clean fluids; provides a balance between efficiency and solids-handling capability.
• Closed (Shrouded) Impellers – Highest efficiency for clean fluid applications; enclosed vanes reduce turbulence and improve flow.
• Mixed Flow Impellers – Designed for medium-head, high-flow applications in water supply and drainage systems.
• Axial Flow Impellers – Used in low-head, high-volume pumping applications such as irrigation and flood control.
• Vortex Impellers – Non-clogging design for waste water and slurry applications.

Stainless Steel Grades Available

Our pump impellers are manufactured in a variety of stainless steel grades to suit diverse service conditions:

• SS 304 / CF8 – General-purpose grade; excellent corrosion resistance in mild environments.
• SS 316 / CF8M – Enhanced resistance to chlorides and acids; ideal for chemical and marine applications.
• SS 316L / CF3M – Low carbon variant; preferred for welding-intensive assemblies.
• SS 317L – Higher molybdenum content for superior corrosion resistance in aggressive media.
• Duplex SS 2205 (CD3MN) – Combines strength of ferritic and austenitic steels; excellent pitting resistance.
• Super Duplex SS 2507 (CD3MWCuN) – Outstanding resistance to chloride stress corrosion cracking and erosion.
• SS 904L – High alloy austenitic grade for sulfuric acid and phosphoric acid services.

Manufacturing Process – Investment Casting & Precision Machining

Our stainless steel pump impellers are produced through a state-of-the-art investment casting (lost-wax casting) process followed by CNC precision machining:

• Wax Pattern Preparation: High-precision wax patterns are created to exact dimensional requirements.
• Shell Building: Ceramic shells are built around wax patterns for mold creation.
• Dewaxing & Firing: Wax is melted out and ceramic molds are fired to achieve structural integrity.
• Pouring: Molten stainless steel is poured into the prepared molds.
• Knockout & Cleaning: Castings are removed, cleaned, and inspected.
• CNC Machining: Precision machining ensures hydraulic surfaces, bore, and keyways meet exact tolerances.
• Dynamic Balancing: Each impeller is dynamically balanced to minimize vibration in service.
• Quality Inspection & Testing: Dimensional, visual, NDT, and hydrostatic testing before dispatch.
