About Wilfley Pumps and KLD’s Engineering Role
Since 1919, A.R. Wilfley & Sons has led with packingless centrifugal pumps featuring dynamic expeller technology ([https://www.wilfley.com/](https://www.wilfley.com/)). Models like Kpro and AG (4,500 gpm, 450 ft heads) excel in abrasive and corrosive services. KLD Pumps enhances this with heavy-duty pump parts, combating wear (40% solids slurry), corrosion (pH < 3), and obsolescence using CD4MCuN (PREN > 40) and heat treatments for 20% higher fatigue strength.How to Order
