1. Comprehensive Overview: PTFE Block AODD Pumps

What is a PTFE Block AODD Pump? A PTFE Block AODD Pump is a specialized positive displacement pump constructed by machining the fluid chambers and manifolds out of a solid, virgin (or conductive) PTFE block, rather than using molded plastic or cast metal.

Driven by compressed air, dual diaphragms move back and forth to create vacuum and pressure, transferring fluids safely without electrical hazard or dynamic seals. Machining the pump body from a solid PTFE block provides unmatched structural integrity, chemical resistance, and longevity when handling aggressive or ultra-pure chemicals.

Key Technical Advantages Ultimate Chemical Resistance: PTFE is nearly inert to virtually all acids, bases, solvents, and reactive chemicals across a broad temperature range.

Heavy-Duty Structural Integrity: Machined block construction eliminates molded stress points, porosity, and weak seams, making the pump highly resistant to thermal expansion, mechanical stress, and pipe.
