Understanding the Nature of Corrosion​​

Three common corrosion types affect hydraulic pumps:

General corrosion: Uniform surface degradation from moisture or chemicals.

Pitting corrosion: Localized pits that penetrate deeply into materials.

Galvanic corrosion: Accelerated corrosion when dissimilar metals contact in corrosive environments.

Selecting the Right Material​

ERL130BFG2820NNN3S1BPA1NNNNNNNNNN hydraulic pump.Choosing corrosion-resistant materials is vital. Stainless steels (high chromium/nickel) offer excellent resistance. Titanium and specialized alloys provide alternatives for extreme conditions.

Applying Protective Coatings​

Coatings enhance pump corrosion resistance. Options include:

Epoxy coatings: Tough moisture/chemical barriers for diverse applications.

Polyurethane coatings: Flexible chemical-resistant films for moving parts.

Zinc coatings: Galvanization uses sacrificial zinc layers to protect base metals.
