To enhance chemical resistance and maintain thermal stability in aggressive chemical environments, fluoropolymer linings are commonly used for pump parts. These linings offer superior protection and durability, making them ideal for handling corrosive substances.

DuFlon manufactures a wide range of components for centrifugal pumps, offering precision-engineered parts lined with high-performance fluoropolymers:

1. Pump Casing
•Acts as the outer shell of the centrifugal pump
•Internally lined with: PFA, PVDF, ETFE or UHMWPE,

2. Casing Cover
•Covers the pump casing and maintains internal pressure
•Lined with: PFA, PVDF, ETFE or UHMWPE,

3. Impeller
•Available in various designs including closed or open impellers
•Customized to suit specific flow and pressure requirements

4. Pump Shaft
•The central rotating component
•Externally lined with PFA for corrosion protection

5. Bearing Holder and Frame
•Houses the bearing and supports the pump shaft
