Abstract:

A series of abrasion tests was performed on 21 different commercial air-cured brush-on synthetic coatings to determine their suitability for use in dry-dock pumps which transfer abrasive mixtures. Gaco N-29 Cold Bond Neoprene, a sheetstock bonding agent, was found to be superior to all coatings tested for resistance to abrasion. This coating, applied about .54 inch thick to the internal surfaces of a ballast compartment pump on the AFDL-6, remained soft and resilient after 26-12 months in service, and there was no apparent wear. It is recommended as an abrasionresistant maintenance coating. It is also recommended that the Procedure for the Protection of Salt Water Pumps with Neoprene Coatings, Appendix B, be adopted as a maintenance procedure for AFDL pumps, and that consideration be given to using a similar procedure for Naval shipyard dry-dock drainage pumps.
