Overview
Vapor bubbles collapsing against the trailing edge of pump impellers, turbine runners, and rudder surfaces drive cyclic micro-jet impacts that pit the substrate and accelerate fatigue cracking. Belzona 2141 (ACR-Fluid Elastomer) is the cold-applied polyurethane lining engineered for this duty, with documented water-velocity tolerance to 115 knots; it pairs with Belzona 1341 (Supermetalglide) for the smooth, hydrophobic finish that restores hydraulic efficiency on volute and runner surfaces. Application happens in the existing tear-down window with no welding, no post-machining, and no return trip to the OEM.

About Pumps
Cavitation pitting on impellers, abrasive wear on volute liners, and corrosion of pump casings drive most pump downtime in industrial service. Belzona repair composites and coatings let plants restore lost wall thickness and add an erosion-resistant finish without removing the pump from foundation.
