Anti-corrosive Cooling Tower Pumps

Engineered to withstand aggressive water chemistry and harsh environments.
Anti-corrosive cooling tower pumps are specifically constructed from materials that resist degradation from scale, chlorides, sulfates, and water treatment chemicals common in open-loop tower systems. EKG Malaysia supplies and installs these durable pumps, ensuring long service life and reliable performance in demanding industrial and commercial cooling applications.

Key Corrosion-Resistant Materials & Their Applications:

• Bronze-Fitted Construction: Standard upgrade; bronze impeller, wear rings, and shaft sleeve for improved resistance to general corrosion.

• Stainless Steel (AISI 304/316):

  • 304: Good for general tower water with moderate chloride levels.

  • 316/L: The standard for harsh duty; superior resistance to chlorides, acids, and coastal/saline environments.

• Duplex & Super Duplex Stainless Steels: For extreme chloride exposure or aggressive chemical treatment programs.

• Specialized Coatings & Linings: Epoxy, rubber, or thermoplastic linings for severe erosion-corrosion or specific chemical resistance.

• Non-Metallic Pumps: Constructed from CPVC, PVDF, or FRP for highly aggressive chemical or acidic cooling waters.

Why Standard Cast Iron Pumps Fail in Tower Service:

• Galvanic Corrosion: Dissimilar metals in contact accelerate decay.

• Erosion-Corrosion: High-velocity water and suspended solids wear away protective layers.

• Chemical Attack: Oxidizing biocides (e.g., chlorine, bromine) and pH adjusters degrade materials.

• Crevice & Pitting Corrosion: Under deposits or in stagnant areas.

Our Material Selection Process:
We analyze your water chemistry report (pH, chloride concentration, LSI/RSI, treatment chemicals) to recommend the most cost-effective, durable material for your specific conditions.

Common Applications for Anti-corrosive Pumps:

• Coastal or marine installations (high salt aerosols)

• Industrial plants with process contamination in cooling water

• Systems using aggressive water treatment (high chlorine, acid feed)

• Brackish or seawater cooling towers

• Towers with poor water quality control

Our Anti-corrosive Pump Services:

1. Water Quality Review & Material Recommendation: We advise on the optimal construction material.

2. Pump Selection & Supply: Providing pumps from manufacturers specializing in corrosion-resistant designs.

3. Professional Installation: Ensuring proper grounding/isolation to prevent galvanic corrosion with connected piping.

4. Preventive Maintenance Plans: Scheduled inspections and parts replacement to maximize service life.

Specify for the water, build for longevity.
The right materials prevent premature failure and protect your cooling system investment.
