Marine Seawater Pump Refurbishment Solution

Resimac’s Marine Seawater Pump Refurbishment Solution.

Resimac’s Marine Seawater Pump Refurbishment Solution was implemented in Portugal to address significant internal abrasion and external corrosion on a seawater pump. The customer sought a cost-effective solution to restore both the internal and external surfaces of the pump, ensuring long-lasting protection and avoiding the expensive replacement of the pump. This solution not only extends the pump’s operational life but also helps minimize future maintenance costs.

Resimac’s Stainless Steel Seawater Pump and Pipe Protection Solution:

Abrasive blasting of internal and external surfaces to ISO 8501/4 SA 2.5 (SSPC SP 10/NACE 2) standards to ensure an optimal surface profile.
Rebuilding internal pitted sections with Resimac 201 Ceramic Repair Paste.
Applying two coats of Resimac 202 Ceramic Repair Fluid to protect internal surfaces from future abrasion and erosion.
Treating external surfaces with two coats of 501 CRSG to provide long lasting corrosion resistance.

Application Details Marine Seawater Pump Refurbishment Solution:

The internal and external surfaces of the marine seawater pump were abrasive blasted to create a 75-micron surface profile. Damaged internal pitted steel areas were rebuilt using Resimac 201 Ceramic Repair Paste, which was applied to repair and restore the affected sections. After the repair, two coats of Resimac 202 Ceramic Repair Fluid were brushed onto the internal surfaces, each with a nominal thickness of 350 microns, offering strong abrasion resistance. To protect against external corrosion, two coats of Resimac 501 CRSG were applied to the pump’s exterior, providing durable protection in demanding marine environments.
