Stainless Impeller

Corrosion Resistance as a Core Advantage

A Stainless Impeller is specifically designed for pumping applications where corrosion resistance, durability, and chemical compatibility are critical.

Manufactured from high-grade stainless steel (304, 316, or duplex grades), the impeller provides long-term stability in acidic, alkaline, or saline media.

Key material benefits:

High corrosion and oxidation resistance

Long-term dimensional stability under varying temperature and chemical conditions

Low maintenance requirements due to reduced fouling and pitting

Frequently Asked Questions (FAQ)

Q1: Which stainless grade should I choose?

A: 304 is suitable for general corrosion resistance, 316 for higher chloride tolerance, and 2205 duplex for highly aggressive or seawater environments.

Q2: Can the impeller be customized for solids-containing fluids?

A: Yes. Semi-open or open stainless designs are available for moderate solid content.

Q3: How is corrosion resistance verified?

A: Each batch is tested according to ASTM or ISO corrosion testing standards.

Q4: Can surface treatment improve durability?

A: Yes. Polishing, passivation, or electropolishing can enhance corrosion and wear resistance.

Q5: Are Stainless Impellers suitable for food and pharmaceutical applications?

A: Yes. Materials and surface finish can meet hygienic and regulatory requirements.
