OEM vs. Aftermarket Parts: Why Choose KLD?
Compare KLD’s aftermarket Durco FlowServe 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 | CD4MCu (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 chemical plant reduced casing replacement frequency by 40% using KLD’s CD4MCu casing vs. OEM, saving $30,000 annually.
About Durco FlowServe Pumps and KLD’s Engineering Role
Durco, now part of FlowServe, has been a pioneer in chemical process pumps since the early 20th century, offering robust designs like the Mark III ([https://www.flowserve.com/](https://www.flowserve.com/)). Models excel in corrosive and high-pressure services. KLD Pumps enhances this legacy with heavy-duty pump parts, using CD4MCu (PREN > 40) to combat wear (50% solids slurry) and corrosion (pH < 3), ensuring longevity and performance.
