Corrosion Conquered: Odour-Free Protection for Monoblock Pumps

About the company

A leading manufacturer of cast iron monoblock pumps, specializing in durable fluid transfer solutions for agricultural and industrial applications.

The Challenge

The manufacturer faced persistent internal cavity corrosion and unpleasant, foul odours on the shop floor when using a conventional mineral oil-based, water-soluble rust preventive in their cast iron pumps. They urgently needed a reliable solution to prevent internal corrosion after the initial pump inspection without compromising the work environment or product quality.

The Solution

Lubeco recommended and provided Lubeco Coroseal 33 – Synthetic Corrosion Inhibitor for a trial. This water-soluble corrosion protection product was applied by filling the internal cavity of the monoblock pumps.

Result

  • No bad odour was reported.
  • The rusting issue was eliminated.
  • The product provided excellent rust protection.
  • It formed a dry-to-touch film.
  • The corrosion protection was sustained for at least 4 months.
  • No oily layers were observed in the valves

Testimonial

Switching to Lubeco Coroseal 33 completely resolved our internal cavity rusting and foul odour issues. The dry-to-touch film provides long-lasting, reliable protection for our cast iron pumps without leaving any oily residue in the valves, making our post-inspection process seamless
