PTFE AODD Pump — Chemical Duty Air-Operated Double Diaphragm Pump
PTFE (polytetrafluoroethylene) is the benchmark material for aggressive chemical transfer. A PTFE AODD pump handles nearly the full pH range — strong acids, caustics, solvents, plating solutions — without corrosion, swelling or degradation. For chemical plants, plating lines and dosing applications, PTFE wetted parts deliver the widest chemical compatibility of any pump material.
PTFE AODD Pumps — Key Specifications
| Port Size | 1/4" – 2" (BSP / NPT) |
| Flow Range | 0 – 300 L/min (0 – 80 GPM) |
| Max Air Pressure | 8.4 bar (120 psi) |
| Wetted Materials | PTFE body, PTFE diaphragms |
| Temperature Range | -60°C to +260°C |
| Chemical Resistance | Excellent — nearly full pH range, acids, solvents, aromatics |
⚠️ PTFE diaphragms are typically overmolded or backed by a secondary elastomer for flexibility. Confirm the pump model and diaphragm construction with our team before ordering.
Applications
Diaphragm & Elastomer Options
Match the elastomer to your media — the diaphragm is the highest-wear component and its material must be compatible with the fluid.
