OEM vs. Aftermarket Parts: Why Choose KLD?
Compare KLD’s aftermarket Wilfley pump parts to OEM options:
Feature | KLD Aftermarket | OEM |
---|---|---|
Cost | 20-30% less than OEM, same quality. | Higher due to branding and overhead. |
Lead Time | 2-4 weeks, fast production. | 6-8 weeks, supply chain delays. |
Materials | CD4MCuN (PREN > 40), Duplex SS. | Standard alloys, less optimized. |
Customization | 3D scanning for legacy/upgraded parts. | Limited to current models. |
Support | Engineer-led, 24-hr quote response. | Generic support, slower response. |
Case Study: A phosphoric acid plant cut downtime 50% (from 20 to 10 days/year) using KLD’s CD4MCuN impeller vs. OEM, saving $50,000 annually.
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.
