Belzona 1341 super metal glide reduces skin friction. (drag) Liquid conveying systems are built of metal materials which do not have optimum smoothness and become even more rough in service. Moving bodies of fluid encounter frictional drag that reduces the operational efficiency of the system. Additionally, many substances have a strong affinity to metal from the attractive forces between for example, water and steel, being greater than the cohesive forces between water molecules. A properly formulated coating can be installed that will have a very weak if not hydrophobic, attraction.
A naked metal pump or pipe will create a boundary layer of fluids interacting with the substarate that become stationary and the molecules flowing over this layer will slow down due to viscous shearing, and the layer flowing over it will slow and so on...
A proprietary technology has emerged that stands up to erosive forces(cavitation, impact, and sliding abraision) while preventing frictional drag by being hydrophobic(low electronic affinity to water molecules), induces slip at the boundary layer, eliminates turbulent flow, and thus reduces skin friction.

Over time the main cause of lost efficiency in water pumps is from the deterioration in surface finish. 1341 from Belzona Polymerics resists impingement and erosion/corrosion, thus keeping the pump operation in its ideal peak efficiency for an extended lifespan.
