Material Options for Water Treatment Environments
Depending on the application and exposure conditions, Shivam Engineering & Fabrication offers different construction materials:
- Cast Aluminum (LM-6 / LM-25) – Standard for aeration blower impellers. Lightweight, corrosion-resistant, high efficiency.
- Stainless Steel SS304 – For pump impellers, mixer impellers, and special blower applications. Good corrosion resistance for most water treatment environments.
- Stainless Steel SS316 / SS316L – For highly corrosive environments – coastal STPs, high chloride water, chemical ETPs, saltwater intake.
- Epoxy-Coated Cast Iron – For less corrosive applications (sludge pumps in non-aggressive environments).
- Hardox / AR Plate – For abrasive applications (grit handling, sand-laden water).
High-Efficiency Impellers for Energy Savings

Frequently Asked Questions – Impeller for Water Treatment
1. What is the best impeller type for STP aeration blowers?
For STP aeration blowers, backward curved impellers are the most common choice, offering 80-85% efficiency with non-overloading power characteristics. For large plants (5,000 CFM), airfoil impellers (85-90% efficiency) are recommended for maximum energy savings.
2. What material is best for impellers in coastal STPs (high salt exposure)?
For coastal STPs with high salt exposure, we recommend SS316 stainless steel for pump and mixer impellers, and specially coated cast aluminum or SS304 for blower impellers. SS316 offers superior pitting and crevice corrosion resistance in chloride-rich environments.
3. Can you manufacture replacement impellers for imported aeration blowers?
Yes. Shivam Engineering & Fabrication manufactures exact replacement impellers for all major blower brands including Howden, Gardner Denver, Atlas Copco, Aerzen, and others. We can work from samples, drawings, or 3D scans.
4. Do you provide high-efficiency impellers to retrofit existing blowers?
Absolutely. We can design and manufacture high-efficiency impellers (backward curved or airfoil) to retrofit your existing blower. Many customers achieve 5-15% energy savings with a simple impeller replacement, providing excellent ROI.
